There's only one modeling exercise this week. This one is really going to reinforce your ability with the Revolve and Sweep features. It may be a bit more challenging than previous exercises, so I've generated the screenshots you see here as "hints" for what steps to take and in what order. Since this model is composed of soft lines, the exact shape and dimensions are not important (indeed, you may want to play around with the shapes to suit your own style). A few notes to get you started: - The model is all one body, thus "Merge result" is checked for all features.
- There are two Circular Pattern features (Insert | Pattern/Mirror | Circular Pattern). Use the "Equal spacing" checkbox in that feature to get the appendages spaced evenly around the central axis. For these patterns, you're going to want to select the Sweep feature along with the fillets connecting it to the main body in the "Features to Pattern" input area.
- You'll need to define a central axis for the circular pattern features. Use Insert | Reference Geometry | Axis, and define the axis as the intersection of two planes (probably your Front and Right planes).
- Note that for the bottom appendages (feet), the sweep guide sketch actually connects with the end of the sweep path sketch. This basically means that the sweep profile shrinks to zero size (a point) at the end of the sweep, and creates the smooth end of the foot.
Files: Note that for clarity, the PDF is a side view of the model with only one of each type of appendage, prior to the circular patterns that copy each of them. Due: Feb 23
