TEACHING ASSISTANT SCHEDULE
Anna Bechtel and Daniel Ziegler are this term's teaching assistants. They are a resource for you to utilize for asking questions and problem solving. Their weekly schedule with their contact information is listed below.
INTRODUCTION - ALIAS INTERFACE, NURBS CURVE AND SURFACE ENTITIES
Following videos cover introduction to the interface, view cube conventions, marker menu, and the project folder. Curve creation , curves on surface (COS), and trim/untrimming surface operations.
PROJECT - UNDEFORMED AND DEFORMED SOAP BARSimple
use of surface skins across many profiles. Use of continuously
calculated ruled surfaces around a band soap design. All surfaces get
oriented in a Z up direction for milling in Delcam PowerMill.
INTRODUCTION TO VARIOUS TOOLS - TRADITIONAL CHESS PIECE OBJECT Several Tools are introduced, Surface Draft, Surface Revolve, Surface Primitive Plane, Surface Swept Rail, and Surface Fillet. Workflow of Surface to Shell Object to Mesh for STL file output to an additive 3D plaster printer is demonstrated.
PROJECT - SAND CASTING MATCHPLATE - PLASTER PRINT WORKFLOW FOR PATTERN
This project introduces the
design challenge of the parting plane, necessary draft for surfaces, and use of
fillets. A reference WIRE will
need to be the starting point for your CAD. Remember the following criteria:
- Start with the WIRE reference file to keep geometry properly centered and constrained in size. The build envelop is 3.0000 inches (X) by 3.5000 inches (Y) by 0.4375 inches (Z).
- Draft angles of extruded features need to be at least 3 degrees (preferably 5 degrees) in the proper direction. Larger draft angles are fine.
- Inside fillet radii need to be larger than 0.060inches.
- Outside fillet radii need to be larger than 0.060inches.
- The minimum thickness a feature can be 0.1875 inches.
- Make sure there is a 2 to 1 ratio of a feature in recess or relief.
- Preferably no text, as it produces frequent features too thin.
- No through holes or void features. These are possible as secondary operations. Have your Making of Things professor evaluate.
PROJECT - BOTTLE DESIGNED FOR VOLUME AND RENDERING
This project presents the
design challenge of desired volume for a bottle. Pick or design a brand for bottled liquid (water, juice, energy drink, etc.). The design must deliver 20oz of water . Remember the following criteria:
with metric Solidworks construction settings (refer back to the video if necessary).
- The outer surfaces must maintain a volume greater than 592,000 cubic millimeters, but less than 622,000 cubic millimeters. This represents a 5% deviation allowance.
- You will provide a two wire files, one that is only the design properly centered on the origin and the other that will be used for your renderings.
- Provide at least two renderings that are no larger than 1500 pixels in height or width. Once render will be only one single bottle centered, the other multiple bottles in a composition with each other. Only a sweep table should be implemented (no real life composite, only a sweep table background).
- Use an archive .zip file for all files labeled as LASTNAME_FIRSTNAME_bottle.zip that will be uploaded to blackboard.
