Creo2 Rounds

[DeanLong]

Anyone have the super extra special functionality of rounds switching from solid to surface without you telling to do so?

[bgruman]

Yep, In Creo2 (and also WF4 if I remember correctly) it happens under the
options menu.

The trick is, you can only place rounds on one quilt (or solid body) at a
time. Rounds on a separate quilt (or solid body) need to be done in a
separate feature.

For me, it happens when I am working on a model that has multiple quilts
(and/or with a solid body) that have not been merged together yet... I'm
happily clicking along selecting the edges I want to round and then I
accidentally pick an edge that belongs to a different quilt or solid.
That's the instant it happens. ProE automatically changes the round to a
surface round. (This happens in the background with no warning) Even
when I realize that I have picked an incorrect edge, I un-select the edge
I didn't mean to pick and continue on to finish my feature... ProE doesn't
change it back. Like the trip switch on a GFI wall plug... Once its
tripped, its tripped. To fix it, you have to go back into the options tab
and set it back to solid, (or same quilt)

Hope this helps.

I checked that as I thought maybe that is what happened but there are no
explicit surfaces or quilts in that area at all.



However, It must be related to that. In this case the surfaces are not
directly related to the round feature rather there is a "base" feature first
that the solid cut and resulting round was explicitly created upon. That
make sense? Imagine a cube build up from six planes, merged, solidified then
a cut added then rounds added to that. I think there was a merge order
reversed in the base "cube" somewhere along the road that caused the round
to unlink and consider itself surfaced. Uggggg!



It sucks because I look like a Putz for not "seeing" the round is now a
surface when it was solid at one point on a 3200 feature model.



Thanks

I hear ya... I can see how a re-ordered merge could definitely cause that
to happen.

I hate it when you insert into a complex model to make changes, then
during the regen ProE doesn't Fail like it used to... Instead it makes
assumptions and doesn't tell you about it. (I would much rather have it
fail and tell me something is wrong) Then, you don't see the change right
away and you look like a Putz in front of the client. I think it has
happened to every Pro/E person I know at one time or another...
Hopefully you caught it before they were cutting chips!
