You can create surfaces to cap ribs in models. This is useful for supporting rib machining in PowerMill by creating capping surfaces that allow roughing over rib channels.
To create a capping surface:
For example:
— The selected
Top faces that the capping surfaces will be created between are highlighted. A graphical arrow appears at the centre of the selection showing the direction of the current principal plane.
— Ribs to be capped.
— Internal cavity (see below).
For example:
— The selected Rib faces that will be capped are highlighted.
In the
Rib Capping dialog, the
changes to a
and
No items are selected is replaced by a message specifying the selected number of faces or surfaces.
If the operation fails, the error message No rib surfaces created or Input faces were unusable is displayed at the bottom of the dialog.
This option also relaxes the tangent continuity condition if any problems are detected in the faces.
