Project One is evaluated as follows.

First, I take a look at the Rhino 3-D model. I look for adequate and accurate detail of all external and (where possible) internal parts, arranged in a well-organized system of layers. Since the model must be watertight, i.e. it must be constructed entirely of valid closed polysurfaces, I perform the following set of analyses:

• Turn off all 2D layers (all 2D geometry should disappear)
• SelBadObjects (nothing should be selected)
• SelClosedSurfaces, SelClosedPolysurfaces, Hide (all 3-D geometry should disappear, and nothing should remain)

Next, I take a look at the STL file. If the 3DM was watertight, then I don’t expect any problems, but I perform the following analysis regardless:

• Set to Rendered View
• SelOpenMesh (nothing should be selected)

I also check to make sure the tessellation is suitable for 3D printing. Note that Rhino’s default Export > STL settings are generally suitably accurate.

The drawings and renderings are to be prepared on two 11″ x 17″ pages, and uploaded as a single PDF. In the drawings, I’m looking for:

• Appropriate lineweights applied to appropriate lines (Make2D is limited: you should be filling in gaps as necessary)
• Correct layer order, such that the heaviest lineweight lies on top
• Appropriately assigned and composed dimensions
• An appropriate selection of orthographic views, and an appropriately selected perspective or parallel view

In the rendering, I’m looking for:

• No blown-out highlights or underexposed shadows: basically, no pure black or pure white
• Reasonable colour selections for different parts of the object (materials are encouraged but not required)
• Object-appropriate lighting (generally from above)

Good luck on Project One!
