 Nifty Bits

 
  • How do I make SketchUp run faster?  There are enough of these tips to have its own page.
  • Camera > Previous restores your last camera positions.  It's so useful that it deserves to be added as a keyboard shortcut.
    • Use it if the camera gets 'trapped' inside a model while orbiting to go back to the last good location
    • It's also good to set the identical camera position for multiple Scenes.  Adjust the camera and save/update the first Scene in the Scene palette.  Select the next Scene tab.  If the camera moves to some other location, select Camera > Previous to restore the camera position of the first Scene.  And be certain to update the Scene to save.
  • Use Section Cuts to examine the inside of a model for unnecessary geometry to delete.
  • If a text leader needs to be repositioned, select it and switch to the Move tool.  The Scale tool also can be used.  Tug on the bounding box handles to reposition the leader.
  • While working with any tool, move the tool over any geometry you want in the middle of the workspace and double-click the middle button - the scroll wheel.  
  • Convert your SketchUp models to PDF format using free software  DigitalThumb - Group discussion on making PDFs for the SketchUp free crowd.
  • To soften harsh shading, open the Shadow Setting window and move the Light slider to a darker value and the Dark slider to a light value.
  • Group a Line - You cannot make a group or component by selecting a line, right-clicking and choosing the option on the context menu.  But you can use the Edit menu option or a keyboard shortcut for making a group or component.
    • Make an image, like a landscaping element transparent PNG, a component by selecting a line with the image.  Go into edit the component to remove or hide the line.  An image does not have edges, so this will help lower model geometry.
  • How do I open skb files  Four ways to open the backup file in SketchUp. xxxx [dead link]




Change Thumbnails

 


Add Geographic Locations to Model Info

  • TaffGoch - The default longitude/latitude data is stored in a DAT file in the program directory.  In Windows, open the DAT file in Wordpad (Notepad will not work) to add more default city location data.  In Mac, open the DAT in TextEdit.
    • Windows - C:\Program Files\Google\Google SketchUp 6\Resources\en-US\locations.dat
    • Mac - /Applications/Google\ SketchUp\ 7/SketchUp.app/Contents/Resources/English.lproj/locations.dat

 Attribute Reporting  

Within SketchUp...
  • Note that the report generated by the Model info>Statistics window can be copied and pasted into another program like Excel as a tabbed list.
  • You can check "Components only" to get a list of components - check Show Nested Components, if your items are buried in other components or groups.
  • SketchUp 7 Pro added Dynamic Components, which among other things will allows a variety of attributes to be added to a component.  Along with that feature is ability to send model attribute to a CSV or HTML file for Pro users through File > Generate Report.  

There are several other ways to write and generate attributes:

 Back to the Basics

 
 

Plain Jane, Patent drawing-like Style
  • Enjoy 3D modeling in SketchUp with whatever style is comfortable.  Using a style with some face shading, like the default Architectural style may even help you 'see' and execute the model.  and set up Scenes with specific camera projections and style attributes for final presentation.
  • Eliminate shading/shadow
    • Open Shadow Settings: Window > Shadow
    • Shadows off
    • Use sun for shading
    • Putting the Light slider to 0 and the Dark slider to something like 80 seems to make the materials come nearest to the Materials browser swatches. It may depend slightly on your screen. The Light slider flattens the lighting and then the overall brightness is adjusted with the Dark slider.





  • Save a Template: If this set-up is done often, save these settings (everything: shadows, Styles, Scenes, Layers...) as a Template through File > Save as Template.  Access templates through Window > Preferences > Templates.  Of course, you should delete/purge all models/components, styles, layers, materials you do not want to clutter up your next project before making the template.  To purge: Window > Model Info > Statistics > Purge Unused.
  • If you do not want to bother with a template, save most of the settings (sans shadow settings) as a custom Style.  Open the Style browser, Window > Styles.  Create a new style by clicking on .  A new style will appear In Model,  In Model .  After any changes/adjustments, update the style,  Refresh .  To save the Style for future use, open the second Styles browser, , and drag the new Style to one of the existing Styles through the collections drop down list or create and save a new collection through the options under the details menu, .
  • Axo + Iso View  TIG - Plugin to change current view to the axo/iso format desired and model-extents are zoomed.
  • For more on hatch patterns, variety of line weights and dashes, try SketchUp Pro's LayOut.  For more CAD-like options and useful plugins for SketchUp, including dashes and line options see more below...  xx

For a true, isometric drawing use LayOut, a companion program which comes with SketchUp Pro.
To get an 1:100 iso view where the axis directions are to scale, you must use 1:81.6497 as the scale. See the attached isoscale.skp for why.


 
 

 Modeling Methods

Dynamic Components

 


"Drafting"

General Tips

Plugins
  • Axo + Iso View  TIG - Plugin to change current view to the axo/iso format desired and model-extents are zoomed.
  • Eneroth Axonometric Projection  Eneroth3 - Distorts a group or component to resemble an axonometric projection when viewed from above.

Face Me Components

Shadow Studies

Determine building height from Google Earth satellite images
  • Highness of Buildings  Determine building height from images. 
  • The energy analysis plugin OpenStudio has a tool to help calculate the effect of shadows from surrounding buildings. 

Depicting Shadows

  • Exporting just shadows from 3d city  Anssi goes over some internal SU settings in order to export only shadows.
  • Exporting shadows without lines
  • Another method is to paint the model with a completely transparent material. Make a model with default colors. Paint only the faces you want to see, like the building footprint, a color. Make the model a group. Paint the group with the completely transparent material. To turn off edges: toggle off Display edges and Profiles in the Styles palette, Window (SketchUp in Mac) > Styles > Edit > Edges.
  • The World Clock  A good internet site for finding time zones.

Dynamic Components (DC)

  • SunTracker  Requires the plugin scenes.rb to see the component change orientation during an animation with scene changes.  (Open a plain text file, on Windows use a text editor like Notepad, and paste in the text.  Name the plugin scenes.rb and install in SketchUp's Plugins directory.)
    • TIP:  The code snippet for scene.rb needs to be added and saved in a plain text editor (like Notepad, Notepad++ [Windows]). Add the file to SketchUp's Plugin directory. Reload the program if SketchUp was already running. This plugin runs in the background, it will not be listed in any menu. The main value of this plugin is if a scene animation video was created with SketchUp.
    • TIP:  A DC needs to be added to SketchUp without losing its outer component wrapper. Try downloading the DC to the desktop then importing it into an active SketchUp workspace if there are any problems with the DC working as expected.
    • To make this DC react to time/date changes, use the DC Interact tool,.  First make sure the DC extension is active. Go to Window > Preferences > Extensions and enable Dynamic Components. Select the DC in the workspace. Switch to the Interact tool through the DC toolbar (View > Toolbars > Dynamic Components or Tools > Interact. Change the time/date through the   Shadow Settings window or toolbar, then click on the DC with the Interact tool to update the component's position.
  • True dynamic sun tracker  Also requires the plugin scenes.rb to react to scene changes.

                  Cars - and other fast stuff


                  Tips
                  • With so many body style options only limited by the imagination, take advantage of making custom, component libraries.  For example, with a car, model a body half to a good stopping point.  Make it a component and drag that component into a custom library.  That way, when you want to make a new - but similar - car body style, bring in that original component body and rework it.  It saves a lot of time by eliminating the initial modeling set-up steps.
                  • To rework the same component in the same file, right-click the component and select Make Unique.
                  • Scroll down this section to the Organic - Sculpture sub-section for another list of useful plugins.

                     Match Photo / Advanced Camera Tools


                    Bit of SketchUp History




                      Tutorials




                      Photogrammetry

                        (Pardon the mess.  This is a new topic under construction after 2014 SketchUp Basecamp conference session.)

                        General, introductory instructions for Match Photo and Advanced Camera Tools (Google Doc) - a SketchUp Pro extension from the SketchUp team - do not cover all possible uses of these two powerful tools.  ACT can be used for more things than the film and television industry.

                        Photogrammetry is the term used to measure physical space from photographs.  


                        Joshua Cohen of Fat Pencil Studio presented his company's use of used both Match Photo Match and Advanced Camera Tools (ACT) to recreate a time-stamped accident scene during SketchUp Basecamp 2014 showcasing his SketchUp photogrammetry work to help TriMet Case Settles.   The 2014 SketchUp Basecamp Photogrammetry Workshop files to examine (note that the football field example has less reference lines in the image and relies more on setting the scene with Advanced Camera Tools.)  Fat Pencil Studio YouTube home with more examples.



                        Setting up a custom camera in Advanced Camera Tools:
                        Note, to obtain accurate information from digital photograph meta data is to use the unaltered (uncropped) size of the digital image being used.  A cropped images should not be used as that may adversely affect the results.  Meta data is information 
                        Finding the data

                        Focal Length is found in the image meta data.  In the viewer IrfranView, look for Focal Length under Image > Information > EXIF Info.




                        Camera Sensor width in mm is the value to use as the Image Width in the ACT custom camera properties.  Depending on the camera, it can take more effort to find this measurement.  Most common camera sensor sizes can be found on Wikipedia.  Find the camera model under the EXIF meta data.  Look for comparative charts of real sensor size, like this one for the Nikon that took this picture.



                        From Wikipedia

                         Entering the data

                        Add a camera.  




                        With a Scene selected, r-click on the workspace to open the edit camera menu.





                        TIP:  If you plan on using the same camera often, add the camera specs to ACT by editing the cameras.csv file.





                         

                         LayOut



                        Tip: controlling the extension overruns
                        It's not easy to find, but here's how you can control the length of the extension overrun (from the SketchUp developers):
                          1. With the Select tool, double-click on the dimension to enter the dimension 'manipulator'.
                          2. Select one of the extension lines.
                          3.  In the Shape Style panel, click on the End Arrow dropdown, and select a smaller point size. The extension's overrun should get smaller.
                          4. Select the other extension line.
                          5. Repeat step 3. 

                        To create dimensions like this every time you use the dimension tool:
                          1. Pick the Style tool.
                          2. Click on the dimension you just modified. This will sample the dimension's style.
                          3. Pick the Dimension tool and create a dimension. It will use the sampled dimension style.

                        It's possible to change the dimension line style so it's different from the extension lines:
                          1. With the Select tool, double-click on the dimension to enter the dimension 'manipulator'.
                          2. Select one of the extension lines.
                          3. In the Shape Style panel, choose a new stroke color, dashed pattern, etc. The extension line will show the new settings.
                          4. With the extension line still selected, go to Edit -> Copy Style.
                          5. Select the other extension line. 
                          6. Edit -> Paste Style. The two extension lines should match now.

                        To create dimensions like this every time you use the dimension tool: 
                          1. Pick the Style tool.
                          2. Click on the dimension you just modified. This will sample the dimension's style.
                          3. Pick the Dimension tool and create a dimension. It will use the sampled dimension style.



                          Tip: Cropping Images Imported Into LayOut
                          The picture frame cannot be used for cropping, LayOut is a bit limited that way.  But there is a way to do it: draw a rectangle (or any shape) to define your cropped area over the image, select that and the image you want to crop, right-click and select "Create clipping mask" from the context menu. SketchUp Sage Anssi



                          Tip:  To get proper dimensioning on scaled pages, set the scale in two places in LayOut:
                          1. To change the dimension scale, select the dimension tool, open the Dimension Style panel, and set the scale nest to the 'Auto Scale' button.
                          2. To change the SketchUp scale, select the skp model, open the SketchUp Model panel, and set the scale next to the 'Ortho' button.
                          3. More dimensioning tips from MasterSketchUp author, Matt Donley. 

                          Tip:  Many of the plugins listed below, developed to replicate the 'CAD' look, can be very helpful in setting up Sketchup Scenes for LayOut export.  xx




                           

                           Printing


                          There is a glitch in SketchUp that makes image exports of, say, more than 3000 pixels wide or high to fail if antialiasing is turned on. This varies from computer to computer and nobody quite knows why. Also, the antialiasing quality in SketchUp is nothing to write home about, so re-sampling with a good algorithm (like Bicubic in Photoshop) gives you better antialiasing than what SketchUp is capable of. and it also makes the visible edges thinner in relation to the whole image.


                          Want a high-quality image?

                          So, to get a high-quality image, from SketchUp, export the highest pixel level (9999 px is maximum in SketchUp) and import the image into Photoshop and down-sample. 

                          Try LayOut to export.

                          Note: printing with the "Vector printing"(Mac) or "Use High-accuracy HLR" (PC) print setting turned on? They switch printing to pure vector mode, so textures and shadows are not printed.

                          If this isn't the case, you should try updating your graphics card driver or turning off OpenGL Hardware Acceleration (Window menu>Preferences>OpenGL) while printing.

                                Tip:  Photoshop CS4 can import a KMZ file from SketchUp.  The model surface can be painted in Photoshop, then returned to SketchUp as a KMZ import.  In Photoshop CS4, export the file through 3D > Export 3D Layer.


                                Is there a way to COLOR lines to make them appear softer?

                                In SketchUp, Click ... Window (PC) > Styles > In Model > Edit > Edge Settings > Color: By Material

                                Then use the Paint Bucket tool to paint the Edges.

                                Note:  
                                Textured materials can be painted on in addition to solid colors.  But to help avoid blotting the SKP file size, make sure the materials you use have a small file size.  Also, if you purge your SKP file of 'unused' materials and wonder why some materials cannot be deleted from the home menu, those materials may still be painted on some edges.

                                SketchUp is not designed to handle the math required to depict the appearance of realistic lighting. More realistic lighting effects need to be done with ray tracing renderers.  Renderers can even use special files from lighting manufacturers to recreate specific light fixtures.  

                                There are several renderers that work inside of SketchUp and other external rendering programs can import models made with SketchUp.  See the Renderers section on this site's Resources page.

                                Renderers  As time goes on, renderers have been adding real-time animation.

                                Scene Animation Set-Up

                                You can create the illusion of an object moving by creating multiple copies of the object positioned incrementally along the intended path of movement.  In many ways the method is akin to Flip Book animation.

                                • Each instance of the object is assigned to a unique Layer.
                                • The visibility of each Layer is controlled by the Saved Properties of each Scene you create.
                                • Camera Location remains static from Scene > Scene.

                                Open the Layers browser (and/or Entity Info and the other control panels like Shadows and Outliner) while reviewing the scene animation tutorials below in order to study the changing visibility of different elements in the model.  Slideshow animation settings are located at Window > Model Info > Animation.  Right-click on a Scene tab and select Play Animation to run the slideshow.

                                Tips: Anyone who may want to set up a scene animation will end up loving the plugin Add Hidden Layer by Jim Foltz.  The plugin lets you add content to a new layer which will be invisible by default on existing Scenes - a big time-saver on files with many scenes as you will not have to update Scene layer visibilty every time a new layer is added.

                                 Edit > Paste In Place
                                The SketchUp option of Edit > Paste In Place is quite useful for people want to scene animate grouped (or componentized) bits and pieces of geometry as it is easy to see and judge the relative position of the copy to the original as the copy is move.  Copy a group then use Paste In Place.  Move that copy into a new, secondary position.  Then adjust the visibilty of each copy on different Scenes by putting the copies on different Layers (and changing Layer visibility) or simply hiding the groups you don't want to see on specific Scenes (be sure to refresh the Scene each time a Scene change is made.)

                                Prepping CAD imports/exports

                                File preparation is the key to success.  Import only what you need, comprised of elements SketchUp can recognized.  An often used strategy in preparation for import is to work with a sacrificial copy of the CAD file.

                                Look into what’s actually in the files you are trying to import.  Here are just a few of the things to consider when CAD import problems occur:

                                What’s in the file in terms of unsupported* CAD elements?
                                DWG/DXF Supported CAD Elements
                                Was the file properly prepared for import? How should I prepare a CAD file for import into SketchUp?
                                Were the Import Options set correctly? The Import AutoCAD DWG/DXF Options dialog box

                                Tip:  To get a clean, 3D export of true geometry (ie, true arcs), delete all faces before exporting.  Using 2D Tools also makes clean geometry exports.

                                When you import a DWG or DXF into SketchUp Pro, you should check in the import options (Options button on the Import File dialog box) that the import unit is set to the same unit that was used when creating the file. The default import unit is Feet. SketchUp does not read the unit from the file automatically, and the import unit is set independently of the unit you use when modelling. Also, when importing DWG/DXF files exported from SketchUp into some other application, note that the SketchUp exporter has a small bug that leaves the unit factors that are embedded in the file to wrong values (except if you are using inches) so also in other applications the import unit should be set "manually".

                                When you export 2D views from SketchUp to DWG/DXF, note that you can only define a scale if the view you are exporting uses Parallel projection (Camera menu) instead of Perspective. A scale relation to reality is impossible and irrelevant to a perspective view.

                                Another thing that causes crashes or missing geometry is the import unit (see what is behind the Options button on the Import dialog box) being too small. If the file has very small triangles, it may even be necessary to import using a larger unit than originally used to model the thing, and to scale the model back down when imported.

                                If you made it with AutoCad Architecture or some other "vertical-market" version of AutoCad, the 3D objects like walls, roofs etc. are in a proprietary format that cannot be imported directly into other software. AutoCad Architecture has an "Export to AutoCad" function that converts these objects into standard AutoCad 3D geometry.

                                If AutoCAD files are older than version 12 (released about 1993 or 1994), some problems might arise. You can convert old files (from release 10 or newer) to newer formats with the free DWG TrueView from Autodesk. Note that SketchUp cannot import the latest (version 2013) files yet. Usually the reason why DWG files won't open in SketchUp is that they contain objects that are not supported, like AEC objects (like walls and doors created in AutoCad Architecture).


                                Zombies
                                After the DWG/DXF file is imported, a SketchUp dialog will list ignored items.

                                AutoCAD Entities Ignored:

                                    Empty Blocks:    1
                                    Zombies and Others: 5162

                                The "zombies" the report refers to are most probably an indication that the file consists mainly of just the kind of proprietary objects. Zombie objects are proxies that refer to objects created in an application that is missing.  Standard AutoCad can display them with the help of so-called "Object enablers", but to convert them into something that SketchUp can read you need the full originating application and its "Export to AutoCad" function.

                                • Logitech Performance Mouse MX  This mouse has a cordless laser engine with "programmable" buttons.  In other words, you can assign several keyboard shortcuts to the mouse - like Undo and Redo to the Forward and Back thumb buttons.  It even has a plugin called uberOptions to expand the functionality of its SetPoint software. 
                                  • One of the noteable advantages of going to the bother of installing uberOptions is that it will save your mouse button preferences when updating the mouseware.  Follow the upgrading instructions on the uberOptions web site.
                                  • The batteries are built-in, no swapping with your own rechargeable batteries.  Maintenance has meant dusting the laser lens and connection terminals in the recharger for continued good performance. 
                                  • Shop around for best price and good rebate.  Other multiple button mice are out there too.
                                • 3Dconnexion has several navigators for the left hand.  It lets you pan, orbit and zoom with one hand while using another SU tool with the right mouse.  Go-2-School has a video demonstrating some uses of the Space Navigator.
                                • CadRemote  Maide - iPhone / iPad app which will act as a navigator for SketchUp on Mac and Windows.
                                • FPS Nav  Alan Chatham - First Person Shooter Navigation. Use arrow keys, WASD and Numpad to navigate.
                                • Maide Control  3D control input device on an iPad for SketchUp installed on either Windows or Mac - something like the 3Dconnexion navigators.
                                • Got a tablet? Here's a complete set!  Dany0 shares his Macro Key manager for Genius tablets - Optimized for F610.
                                • Remotix  VNC remote access tool for iPhone and iPad to touch/control your SketchUp model on Mac, Windows and Linux.
                                • Sandiotech  3D mouse with drivers for Goggle SketchUp and Google Earth (but you still only do one thing at a time).
                                • Wiimote  Used for presentation - Alex Schreyer
