Assignment Overview 

CAD Assignment 1

Next Assignment: CAD Assignment 2
  1. Create three part files in AutoDesk Inventor (.ipt) using these three engineering drawings: file 1, file 2, and file 3.  
  2. In one of files, there is a designation for a tapped hole that reads M4x0.7 - 6H 'downward arrow' 8.00.  The designation can be read as follows: 'M' is for metric (as opposed to the Imperial system), '4' is the diameter of the screw, '0.7' is the screw pitch in mm per thread, '6H' is a tolerance on the dimensions, and the downward arrow and the 8 represent that the thread goes 8 mm down from the hole.  CAD programs do all of this automatically for you.  You should use the "hole' feature, choose a 'threaded hole,' and play around with the drop down menus from there.   
  3. Assign each part to be made from aluminum.  Instructions to assign materials can be found in your book. 
  4. Find the mass of each part.  
  5. Upload your .ipt file along with the mass of each part to the TA's Google Drive folder.  You will receive this information from the TA. 

Grading

  • 4 points
  • You must complete all three parts
  • All parts must be 100% correct
  • How you create those files is just as important as the final part.  In other words, it is important that you understand the process of creating extrusions, cuts, revolves, and holes in a clean and efficient manner.

Educational Goals

  1. Learn to read a engineering drawing
  2. Learn to create a part file with AutoDesk Inventor
