When you select two lists of surfaces, you provide information about the fillet required and PowerShape can create the fillet quickly.
The surfaces shown below illustrate creating a fillet between two lists of surfaces. The cylindrical surfaces are in one list and the planar surface is in the other:
In our example, all the cylindrical surfaces are selected.
In the Selection part of the dialog, the icon changes from to next to Primary Surfaces.
In our case, we select the plane.
When a surface is selected, the icon changes from to next to Secondary Surface.
If you have selected the wrong surface, deselect it using Ctrl+click.
If you have no surfaces selected, the selection is taken as a single list.
The fillet routes separate the two lists of surfaces.
