PL-04 v2-Model (corrected).pdfPL-04
On this assignment we were tasked with using a new feature of drawing called relative coordinates. We were also tasked with learning how to put dimensions and leader lines on our drawings. Relative coordinates are an easy task to complete, as you just type the length in from the origin whether that be a (x,y) or (-x,-y) going in either a positive positive direction or negative negative direction. The problem that I struggled with was messing up the direction from not adding a negative or flipping the x and y coordinate. The dimensions were a much easier task due to just selecting two points on a dimension and dragging out the line using the dimension command.
PL07-Model (corrected.pdfPL-07
On this assignment we explored different variations of the circle command. We learned the command tangent tangent radius which picks two lines of an object making the circle tangent to those objects, and allows the user to select the radius. The struggles that I had were that I kept selecting the wrong lines to make the circle tangent to. I did well on having all the correct radii for all the circles.
Pl-10-Model.pdfPL-10
On this assignment we learned the rectangular array command. This command allows the user to take an object and multiply the object into many other objects to a set number. This number can vary depending on the rows and columns the user has selected for those. I struggled with selecting the array as individuals due to me creating the array as associative. Associative means the entire array is selected as one object and not multiple individual objects. I created the correct number for the array pretty well on this assignment.
PL-11-Model.pdfPL-11
On this assignment we learned the polar array command. This command essentially takes an object and multiplies the object around a given point. The amount of objects duplicated can be set by the user. It allows for an easy design of an object instead of individually drawing each point and line. I struggled with removing all the small leftover lines which were duplicated and arrayed on my drawing. I did very good at selecting the correct amount of duplicates for my array
PL-14-Model.pdfPL-14
On this assignment we learned how to draw on different views. This can be achieved by switching on the isotopic view command and using F5 to change the views. This allows the user to create an isotopic view also known as a 3d viewing model of the object. I struggled with using the correct view for each part of the drawing. I succeeded at using the right lengths and angles since in the isotopic view the angles should only be drawn at either 30 degrees or 90 degrees.
MCD-102 AUTOCAD II
PL-21-Model.pdfPL- 21
On this assignment we learned how to draw an isometric drawing and a side view using only two views. This can done attained checking all the hidden lines that the drawing gives you and all the current dimensions given. Using these two drawings, draw the last side view. After all three sides are drawn, I proceeded to draw the isometric drawing to finish off the drawing. I struggled with getting the third view to match up, but with all the three views I easily finished off the assignment by drawing the isometric view.
PL-22-Model.pdfPL-22
On this assignment we learned how to use break lines and breaks in a drawing. This can be achieved by going in the draw section of the ribbon and selecting the spline fit command. Using the cursor to go back and forth of a set line will draw a split in the material. I struggled at making the break look nice and I succeeded at drawing the inside of the material to show what the break is actually trying to show.
PL-33-Model.pdfPL-33
On this assignment we learned how to draw curves and radii in an isometric drawing. This can done by using an axis, end ellipse and selecting the isocircle at a set point. Adjusting the radius to a certain length to allow for lines to be connected by a specific curve. I struggled with first learning how to get that specified curve. After learning it, I excelled at getting all of the other curves to match up.
PL-41-Model.pdfPL-41
On this assignment we learned how to insert a complete geometric tolerance. This is done by going into the dimension tab and selecting more. The tolerance command will appear first allowing one to insert a geometric tolerance. Symbols and tolerances are able to be adjusted to what the drawing specifies for. I struggled with getting the geometric tolerannce to align and be the right size for the drawing. In contrast, I found the correct symbols and correct tolerances quite easily.
PL-43-Model V2.pdfPL-43
On this assignment we learned the three circle theorem. This is done by select the end points of two lines and setting the radii to the same. At the point where they intersect, draw another circle with the same radius. This will result in a curve that perfectly connects the two lines to the correct curve. I succeeded at correcting using the three circle method, but struggled with solving how to do the correct curve without learning this method.
MCD-115 MACHINE DRAFTING AND DESIGN
MDD-11-Layout1.pdfMDD-11
On this assignment we learned how to do full-section views. Full section views are, "A section view obtained by passing the cutting-plane through the full length of the object." This is done by using a cutting-plane line and cutting the object in half(180 degree angle). Then you draw the basic side view's exterior. Then you project all the points across from the cutting-plane line to show the interior of the object if you were to cut the drawing from the cutting-plane line. Then you would hatch all the solid material and leave the holes cut in half unhatched, showing the interior of the object. I was successful at using the section view to dimension measurements I could not previously dimension. I struggled with making sure all the lines were correctly projected. I overcame this struggle by redoing all the projections.
MDD-13-Layout1.pdfMDD-13
On this assignment we learned how to do half-section views. Half-section views are, "A view half of which shows normal exterior view and half exposes the interior details," This is done by cutting the front view at a 90 degree angle to expose half of the interior with a cutting-plane line. Then you draw the object at a side views. Then you project over all the points, bores, and angles that you would see if you were to looking in the interior of the cutting-plane line by cutting the side view in half. Lastly you would hatch all the solid materials and leave the bores unhatched. I was successful with cutting the material at the right angle and I struggled with including all the bores that were cut in half. I overcame this struggle by rechecking the bores to make sure I am correct
MDD-15-Layout1.pdfMDD-15
On this assignment we learned how to do aligned section views. Aligned section views are, "A view in which the cutting plane is bent passing though selected features of the object and then removed to be on the original plane." This is used to show the interior of an object at two different views using the same line. We start off by drawing the basic shape of the drawing from the side and then using a cutting-plane line to cut the drawing at certain points and angles which in this case I used a 135 degree angle. Then you project the points that you would see if you were to cut the drawing at those angles and points. Then you would hatch all the solid material and leave the holes non-hatched. I was successful at hatching all the solid material and leaving the holes non-hatched. I struggled with making sure I was not leaving anything out when I cut the part at a 135 degree angle. I overcame this by revisualizing what it would look at if cut at a 135 degree angle.
MDD-18-Layout1.pdfMDD-18
On this assignment we learned how to use multiple section views using multiple cutting-plane lines. Section views are, "The part of an object remaining after a portion is assumed to have been cut and removed." This shows the objects interior and exterior at the cutting-plane line if it were to be viewed going the directions of the arrows. This is done by using a cutting-plane line and dissecting the object at specific points. Then the objects basic side view is drawn. With the basic side view drawn, you can project all the points the cutting-plane line intersects with the solid lines over onto the section views. Then once all the points are correctly projected over to reveal what the interior would look like if seen at that specific view, you can hatch all the solid objects and leave all the holes unhatched. I was successful in hatching the correct solid interior and leaving the exterior unhatched. I struggled with seeing what the drawing would look like at that section view but I overcame this struggle after looking at it for a while.
MDD-19-Layout1.pdfMDD-19
On this assignment we learned how to use auxiliary views. This is done my projecting a view seen at side that its true size and shape cannot be determined. This is done by taking the measurements of angled surface and drawing it directly parallel to show its true size and shape. I was successful at drawing the shape correctly and its size, but I struggled with getting all the dimension lines to dimension correctly. I overcame this by using the aligned command to make sure all the dimensions lined up.

CATIA Part Design & Sketcher
Constraint 5
On this exercise we learned the normal and advanced uses of constraint for a part when sketching and designing. This is done by drawing a part in void space on an axis. Using lines, arcs, and circles the rough sketch is created. The constraints give the lines, arcs, and circles a dimension and location in void space. This is typically done at the origin which is located at the very center of the space (0,0,0). These constraints also create a connection to the other lines whether they be parallel, perpendicular, or tangent. Line lengths, Radii, and Angles are given to fully dimension a sketch. When the drawing is complete the whole sketch will light up green signaling the part is iso-constrained or fully constrained, When the drawing is fully constrained the sketch is ready to be modified.
Patterns Circular
On this exercise we learned the uses of patterns, particularly circular in this example. Circular pattern takes an object and patterns that object around a reference element. This is show in the exercise by all the pentagons and circles surrounding the larger circles. A pattern copies the object you selected and revolves it around a reference point. There are many parameters and options within the circular pattern that can be modified. There are instances, angular spacing, completing the crown, and rows. Instances are how many times you would like to multiply that object, angular spacing is the angle distances between each copied object, completing the crown evenly spaces the copied object with the desired instances, and rows indicate the amount of rows for the all the copied objects. I selected the desired options and created the pattern you see on the left.
Fillet 6
On this exercise, we learned the uses of fillets. Fillets are curves or radii that connect two faces over a hard line. This is done by selecting an edge fillet, then selecting the hard line. Once the line is selected, the option to change the radius is given. This number can be any positive real number as long as the radius does not exceed the length of the object. Whole objects can be selected to fillet the entire object. One of the options given is objects to keep which allows objects to be selected to not be filleted when the entire process is finished. The last option given is blended corners. This allows the user to change whether they want a smooth or hard transition between the two faces.
Hole
On this exercise, we learned how to create holes or bores on an object. The first step to creating a hole on an object is selecting the hole command and selecting a face you want the hole to start on. The next step is to select the hole type. The different hole types are tapered hole, counter-bored, counter-sunk, and counter drilled. In the example, I used the countersunk hole. The next step is to give the hole dimensions, showing the main diameter, the main depth, the limit type, and the bottom type. For the counter-bored and the counter-sunk, the command will require addition dimensions for those hole types. The last step is set a location of where the hole is needed to go. This can be done by going into the sketch of the whole and constraining it to the desired location.
Problem 34
On this exercise, we learned how to take a blue print of a drawing and turn it into a modifiable model. This exercise required us to use sketching, constraints, holes, fillets, pads, and pockets. Pad is a command that turns a 2D sketch into a 3D model. Pocket is the complete opposite of the pad process. Pocket uses a 2D sketch to remove a part of the 3D model where the 2D sketch overlaps. When all the processes are done properly and the whole object is filleted and constrained the object to the left is what you are left with.
CATIA 3D TOLERANCE AND ANNOTATIONS
3DTA - GEOMETRY CONNECTION
On this exercise, we learned how to make geometrical connections. This exercise required us to modify annotations and assign multiple surfaces to that annotation that was originally not there. This can be done by right clicking the dimension, and selecting associated geometry. The next step is selection geometry connection management. This will pull up a screen where you can add and link new faces to that assigned geometry.
3DTA - CONSTRUCTION GEOMETRY
On this exercise, we learned how to add construction geometry to a part. This exercise required us to add planes and axis to a part. This allows for connections and selctions of those planes to create dimensions that were previously not available. This is done by selecting constructed geometry connection app and selecting on a part. Once the part is selected, it will give options of what construction geometry needed for the dimension or call out.
3DTA - DATUMS
On this exercise, we learned how to create datums. Datums are a reference to a side or face of a part. This can create dimensions that call out that face using the datum. We learned how to create datums together and add modifies to those specific datums.
3DTA - PROBLEM 4
On this exercise, we learned how to use all the previous knowledge acquired from 3D Tolerance and Annotation. We used Datums, Dimensions, Modifiers, Captures, Views, Geometrical Tolerancing, and Basic Dimensions to create this part.
3DTA - CAPTURES
On this exercise, we learned how to create captures on a part. Captures are pictures of a part from a specific view to encapsulate the image of a part from any needed direction. This allows a part to be fully shown off and dimensioned in a 2D perspective. This can be done by selecting the Capture command and selecting a view and assigning that capture to that view.
CATIA: WIREFRAMES AND SURFACES
WFAS - BLENDED SURFACE
On this exercise, we learned how to blend two surfaces together. This can be done by using the Blend command. The blend command creates a surfaces between two selected surfaces and blends them together. The way to use the blend command is by selecting the two profiles, in this case the lines that are directly adjacent to each other from each surface, and selecting the surfaces as the support. When that is done, the blend is created.
WFAS - 3D PROJECTION
On this exercise, we learned how to project a profile onto a surface. This allows a flat surface to be projected directly on a curved surface. This is done by using the 3D Projection command. After selecting the command, you then select the profile you want to project, then selecting the surface. As long as the profile is overlapping the surface on a view in a straight path, the profile will appear on the surface.
WFAS - SHAPE FILLET
On this exercise, we learned how to curve two parts into each other. This is done using the Shape Fillet command. To use this command, you must select the two different parts as supports. This will allow CATIA to make a calculated curve to connect these two parts.
WFAS - LAW
On this exercise, we learned how to use laws as angles and radii. This is done using Law command. First select a line as a reference, the using a curved line as a definition. This will save the mathematical features of the curve and the distance between the reference and definition. Then when applying a sweep, select advanced mode for the angle or radius, and the select the law that was just created.
WFAS - EXPONENTIAL SWEPT SURFACE
On this exercise, we learned how to sweep surfaces on an exponential direction. This is done by selecting the Sweep command. Once the command is selected, make sure it is in exponential. The three sub categories of creating different exponential swept surfaces are with a reference surface, with two guide curves, and with a pulling direction. Select the necessary limits to create the sweep. Once the correct profiles and spines have been selected, the swept suface is created.
