Geometry Selection
Introduction
This topic explains the Geometry Selection page of the Lathe Wizard for a Hole feature. This topic will explain the option, provide images of example geometry, and provide a link to the next topic.
The Geometry Selection page
The Geometry Selection dialog box of the Lathe Wizard displays as seen below. This is the first page that you see when you add a feature. The first step is to assign geometry for the feature. This topic will go over how to select geometry for this feature.

Geometry Selection
- Select Geometry - opens the geometry selection dialog to allow you to select the
geometry from which the feature will be created. You can select
wireframe, spline geometry,
Note: For Lathe jobs, draw the profiles in the XY plane of the WCS as the machining origin (work offset) is fixed at the WCS with the machining origin Z-axis aligned to the WCS X-axis. For Mill Turn jobs, you can create the machining origin in any location, so you just need to make sure that lathe profiles are selected from the XZ plane of the machining origin.

Note: BobCAM for SolidWorks uses the selected geometry to set the tool and the depth of the tool. In the case shown above there is a chamfer at both ends complicating matters for us slightly. Selecting the larger chamfer edge in the back will set the depth correctly, but use too large a tool. Selecting the surface itself will select the diameter of the tool correctly, but will need slightly more depth. Selecting the point will set the depth correctly, but set the tool as the default 0.5 inch diameter.
