2. Narrative:

The grid spacing for the object below is 0.250. Students are to use this geometry to develop skills using the solid modeling software. Using the grid, students will determine the measurements for each facet of the part and create the required geometry. Upon finishing the part geometry, the students are to answer the questions in section 5.

3. Concepts:

Sketch environment • Rectangle, line, hole point • General Dimension • Constraints: Coincident, Parallel, Collinear, Tangent

Features • Extrude; Join, Cut • Hole • Fillet
