| Draw your line drawings FOR |
Suppose you want to make your own Line Drawings for your Patent.
just some scheme to show your local Furniture Maker how he'll build
your All-Machine-Tools on one Workbench combo. Or whatever.
Not everyone is graphically gifted, but most anyone can make a 3D object with freeware Wings3D, or any other 3D Program. ...And how you do it?
How to make line drawings
You can make 3D line drawings without an expensive program, and without any drafting knowledge...
You just dowload the free Wings3D, http://www.wings3d.com/
and these tutorials http://www.wings3d.com/doghouse.php
Don't be a lazy sod, go though the motions, it's guaranteed it will teach anyone to do all kinda stuff!
And then to the line tricks...
Wings3D exports your piece to many formats, use the cartoon edges format, (.eps), BUT with the following settings:
Nothing much here, just set it to a high Bounding Box size, and on Show edges, choose None.
Now let's imagine an arbitrary piece, and see it line drawn:
Imagine it's this, a sear for a semi-auto.
Now, it will NOT come a perfect line drawing, good for your Patent,
right away; That's why they charge you an arm and a leg for 3D and CAD
First attempt, it will be like this:
A few lines missing, huh?
Now, there are a couple' triks here, the first being adding a face to
that one on the upper hole, just select the face you don't see a line on
and choose Extract Region – Normal, don't even move the thing, just
click to make the change.
Works like a charm.
Trick two, pretty much as trick one bur more sneaky, is used to make those pins sticking out appear at the base of the piece:
make the pins's faces go Extract Region – Normal, but this tiime, move
them on the x axis, to the base of that piece. It's a lot easier if you
select the main piece and press W, the thing goes wireframe, and you see
when the extracted faces go trough it till they're flush with the main
Let's see what difference that makes;
Yup, went and done it!
All that's left are the inner edge of the lower hole, and the outer edge of the piece.
select the edges you want, and then on the menu that appears when you
click the right button, choose Bevel, then just do a tiny motion, so the
bevel will make a line on the drawing. Keep the faces that come out of
that Bevel action selected, Select Materials - New, on the right button
Menu, choose a black colour for them, and there you go:
So now, go and learn, no reason not to turn your ideas into drawings!
you can also make it draw on a Perspective mode the key to switch
between this Isometric view you see, and Perspective view is the O.
Get to work on it!
Make Human, add some Human Figure to your drawings
Make Human, yet another Open Source Program,
Adds Human Fugure to your Ilustrations, it's just a question of selecting the body parts or complete body, exporting it in .obj format, and going back to Wings 3D, as I explained above.
Also, Google Sketchup came along, and you can make your own Illustrations like the one above, again, for free.
yet the ticket, as you can see a lot of unnecessary lines in there, but
wait, one more trick up the sleeve, on the View Menu, choose Edge
Stile, and un-select every item except Profiles.
Almost forgot, you can add text on Sketchup, too!
And now, this I made for my Invention Blog:
Isometric Drawing with Inkscape
...How about making your own Instructions, by doing Isometric Drawing,
on Inkscape, or any other Vector Drawing Program?
Here's a Tutorial:
Let's pretend we want to figure this piece, with text, and a hole:
As you want to place the object, you Skew it, with various angles, here, it's -30º;
Then you want to know if your picturing a transparent or opaque piece.
Transparent, you just make all lines visible, but if it's opaque, you just want to see the visible ones.
So Fill the object, 255, 255, 255, (white), in this case.
Remember to put the text in the first, upper layer.
As for the hole, you got to make that part, non-existent, by doing Path>Difference:
now for some Magic, an operation called Motion. Here's the thing, with
some edges to be worked out, but you have the makings of an Isometric
As for how to figure out the values for the object's orientation in space, here's a chart for them:
Here's the angles for a front facing solid:
And, finally all other Object orientations:
the wrong lines, on some solids? You just have to select the "face"
that should be up front, and push that face to the top level.
