ENTC 2170 — Assignment 3.2:
Importing 2D CAD Data; Extrusions and Revolves

Generate a 3D model of a C-clamp as shown to the right and to the following specifications: Download the c-clamp.dxf and save it to your hard drive.                 NOTE: If you have trouble downloading the file, right click the above hot link and choose the option for saving the target or hotlinked file.

Open Rhino 3D and import the DXF drawing into a new drawing's TOP view using the File-Import/Merge command. Extrude the frame to a height of 0.485". Create a 3/8" DIA hole thru the right leg of the frame. Create a 1/16" deep slot in the top face of the C-clamp frame Join the various curves for the Screw, Swivel, Handle, & Cap and revolve them around the "Important Points" In the head (thick part) of the Screw, generate a 0.250 DIA hole thru at the point. Using the points as alignment references and the ORTHO drawing aid, move the various pieces into place to create a model of the assembled C-clamp. Before rendering the model, set the Object Properties of the pieces to a color of a 130 Gray. Render your final model and save both the 3D model and at least one (1) rendered image.
