Week 10: CADing Present & Name Sphere

Planes are surfaces that you can sketch on! To use it, click on the offset plane button and then click on an existing plane and drag it out to create an offset plane.

Revolving works a lot like extruding! You select something from a 2D sketch, and pull it into 3D. The difference is that extrusions go in a straight line, while revolving will curve around a line that you select. This line is called the axis of rotation. To use it, click on the revolve button, select a shape from a sketch, and then select a line for it to revolve around.

Normally, an extrusion goes in one direction: the direction you drag it in. However, if you change the direction setting to Symmetrical, the extrusion will go in both the direction you drag and the direction opposite to it!

The project tool only appears in sketch mode. Projecting is a way of bringing the outline/silhouette of a 3D object to a 2D plane (it's kind of like the opposite of extruding). To use it, click on the project button and select the face of whatever you want to project. This will make an outline of the face, and move it to the 2D plane, where you can edit it.

This offset is a tool that only appears in sketch mode. To use it, click on the offset button and then click on an existing line or existing shape, then drag the arrow. Offset will create a copy of the line/shape, and make it bigger or smaller than the original. The measurement that you type in is the distance between the original and the new offset sketch.
