3D Modeling for Model Engine Builders: 'Lucy' the See-through Oscillating Engine - Part Two

摘要

The Frame - Detail 7: The frame is the last part to work on and is another straightforward milling job (Photo 6). Shown in Photo 7 is a close-up of the air entry, air exit, and pivot hole. Modeling the Frame: Step One: Create a new sketch on the right plane and draw the outside profile of the frame as shown in Screen-shot 30. Finish the sketch and extrude it using Mid Plane to a thickness of 1/2". Using the Mid Plane option will extrude the sketch to a total thickness of 1/2", but half in one direction and half in the other. This allows us to keep the right plane centered in the middle of our model.
