Use the Select Concave Radii dialog to select small, concave or convex surfaces in a model. To display the dialog, right-click the model and select Selection Tools > Select Concave Radii.
The Orient surface options enable you to correctly orient your model.
Orient all — Click to automatically reverse the orientation of all the surfaces which are incorrectly oriented in the current view.
Orient selected — Click to automatically reverse the orientation of all the selected surfaces which are incorrectly oriented in the current view.
Minimum radius — Enter the minimum radius of the concave surfaces you want to select.
Include partially concave components — When selected, selects any surface which has a concave region.
When deselected, any surface which is wholly concave is selected.
This dialog can be used in conjunction with the new Minimum radius plane list, which is located in File tab > Options > Application Options > View > 3D Graphics. This list enables you to shade the model from the perspective of the Workplane (the default setting) as opposed to the View (the default setting in previous versions of PowerMill).
