face fillet help points

Does anyone have any idea what the "help points" do in the Face Fillet
PropMgr? If you have an example, I'd like to see it.

 

A help point will resolve ambiguous situations where the face fillet
could go to one side or the other. We have a sample in the 'filleting
collection' under the tutorials tab on our web site
(www.dimontegroup.com).
In the zip file you will find a part, unimaginatevly called 'Sample
shows what 'help point' does in face filet.SLDPRT'. There is a comment
in the relative feature.

Though I have this sample, I have never actually needed to use a help
point on a real model (that I can recall)

Hope this helps,

Sorry if this is just out in low earth orbit but if you have two intersecting
surfaces that don't share coincident edges ( a "+") there are four valid
solutions. It might be a way of solving the ambiguity.

 

A couple other folks have written me offline about this. The help point
seems to only work if there is only one face selected in each selection set.

This seems to break down in situations where an ambiguous selection is
made in a single box. For example, if both ends of a block are selected
in set 2 and set 1 is the top of the block, the help point seems to have
no effect, it follows the face selection order instead.

If you are talking about separate intersecting surface bodies, SW won't
fillet between separate bodies, the faces have to be part of the same
knit surface body. But you're right about the ambiguity.
