CAD 1

COURSE DES1050: CAD 1
Level: Introductory
Prerequisite: None
Description: Students develop basic knowledge and skills in computer-aided design (CAD).

For this course, we will continue to develop our skills in Autodesk Inventor, with a focus on creating 2D drawings.

Using Autodesk Inventor, Complete the following assignments:

  1. Inventor Assignment 1
  2. Inventor Assignment 2
  3. Inventor Assignment 3
  4. Inventor Assignment 4

Inventor Project

The requirements for the Final Project are as follows:

  1. Choose an object to model in Inventor. You will be given one week of class time (5 hours minimum) to complete the model.
  2. Object chosen must not be too simple. It must demonstrate your knowledge and skills in inventor. Here are some of the functions we have used in Inventor:
    • Creating Sketches
    • Extruding to 3D
    • Drilling holes (countersinking, threaded, etc.)
    • Using constraints.
    • Mirroring
    • Revolving
    • Drawing lines, arcs, circles, splines, etc.
    • Dimensioning
    • Lettering
    • Selecting Materials
    • Fillets
    • Chamfers
    • Shell
  3. Provide at least one photograph of the object you are going to model. Print it in colour (Room203-C Printer) and attach it to this sheet.

Guidelines

  • 50-70% Design and create a model that will 3D print successfully.
  • 70-80% Design and create a model that uses 2 parts that fit together precisely and that will 3D print successfully.
  • 80-90% Design and create a model that uses more than 2 parts that fit together precisely and that will 3D print successfully.
  • 90-100% Design and create a model that incorporates a hinge (3 parts minimum) that fits together precisely and that will 3D print successfully.

3D Printing Reminders

  • Be aware of overhangs and bridges. Minimize them.
  • The printer’s nozzle is 0.4mm, you cannot physically print any details smaller than that.
  • Make all holes and features no smaller than 2mm.
  • Wall thickness should be 2mm minimum.
  • Parts that will fit together must have tolerance (looseness) designed in.
  • Be aware of print time. No 10 hour prints.
  • Be aware of build volume (size). Keep all parts to within a 150mm max dimension.
  • Be aware of build height. See above.
  • Be aware of what causes warping. Choose print orientations to avoid warping.

The rest of the instructions are on the CAD1-Final assignment sheet.
