You can use the Select Part Surfaces dialog to pick surfaces you want to include in your 3D part feature.
Add surfaces you want to machine to the list using the buttons:
-
Add from selected items — Select surfaces in the graphics window and click this button to add them to the list.
-
Delete from selected items — Select surfaces in the list and click this button to remove them.
-
Pick Surface — Click this button to hide the dialog, then pick a surface in the graphics window.
You need to consider the following when specifying part surfaces:
- You cannot manufacture undercut surfaces using 3-axis machining, so it is a good idea to use only surfaces in the feature that can be cut from the setup.
- Some surfaces may be cut from multiple setups to manufacture all parts of the surface. In such situations, a Stock Curve is helpful in limiting the machining area to just those spots that need it.
