Automatic feature recognition (AFR) can only be performed on solid models. If you do not have a solid model, you can either stitch the surfaces into a solid or use another method of feature recognition.
To complete this page:
Select the name of the solid from the drop down
menu, or click the Pick solid
button and pick the solid
in the graphics window.
Click the Options button to view the various options available for feature recognition.
If you want to create a face feature to automatically level the top of the part, click Create face feature.
If you want to group holes into patterns, click Create hole pattern.
The max hole diameter is threshold between holes and pockets. For cylinders larger than this value, a side feature will be created instead of a hole.
If you have any doubts about the validity of the solid you are working with, click the Verify button. It will run a series of checks on the solid and tell you if it checks out.
