Course Description

Introduces manual and computer-aided drafting used to design parts and assemblies. Covers sketching, basic drawing and dimensioning, geometric construction, and multiple views. Focuses on 3-D modeling techniques. ENGR 105, CADD 175 and CMET 237 cover similar material and cannot all be applied to graduation requirements. Prerequisites: ENGR 101 or (placement into MTH 111 and department approval). Prerequisites/concurrent: (WR 115 or IRW 115 or higher). Audit available.

Intended Outcomes for the course

Upon completion of the course students should be able to:

  1. Understand basic geometric relationships.

  2. Create 3D solid models using a parametric solid modeler.

  3. Generate drawings and views from solid models and assemblies.

  4. Create and read technical mechanical drawings using industry standards.

Outcome Assessment Strategies

Individual and full class discussion; lab drawing assignments; exams; and projects may be used to assess outcomtes.

Course Content (Themes, Concepts, Issues and Skills)

  1. Become familiar with the part modeling user interface of the selected solid modeling software program (e.g. understanding the terminology of part modeling modules menu items and identifying related icons)

  2. Become familiar with  concepts of “Design Intent” so that the solid model created of the part is predictable and modifiable.

  3. Become familiar with the sketching interface, menu items and related icons.

  4. Create  sketches, and fix any errors that prevent a successful regeneration.

  5. Create and constrain a 3D part by extruding sketches in one and two directions, understanding the constraints or design intent of the model.

  6. Create and constrain a 3D part by revolving a closed 2D sketch or profile about a centerline, understanding the constraints or design intent of the model.

  7. Create and constrain cuts to be made to a 3D part by extruding a successfully regenerated 2D sketch or profile of the cuts cross-section in one and two directions.

  8. Create and constrain cuts to be made to a 3D part by revolving a successfully regenerated 2D sketch or profile of the cuts half cross-section about the selected axis of revolution by the desired angle and direction of rotation.

  9. Modify the geometry of an extruded or revolved solid model by displaying and revising dimensions from user-defined sketches.Regenerate the modified geometry to update the solid model.

  10. Replicate common features in a solid model by using part-modeling options to copy, mirror, or pattern features.

  11. Be aware that the intended dimensioning scheme of the replicated features depends on the way the dimensional constraints are specified on the initial feature that is used to copy from, mirror, or serve as the pattern leader.

  12. Become familiar with the drawing module interface in order to specify and generate necessary orthographic projected views of the updated solid model.

  13. Become familiar with the dimensioning options available in the drawing module.

  14. Document the solid model by producing fully-dimensioned, and annotated engineering detailed drawings using the options provided in the drawing module.

  15. Become familiar with the assembly modeling option of the part modeling module and constrain the first part model to the assembly work-space by employing default assembly datum planes and axes.

  16. Create and constrain an assembly model of previously modeled parts by mating, aligning, and/or inserting the related features to be joined between two or more part models.

  17. Document the assembly by producing an assembly drawing with necessary views, assembly dimensions, assembly notes, and a bill of materials. Use options provided in the drawing module
