How to best practice surfacing

Hi guys.

I'm currently trying to get the hang of doing surfaces in Creo2.

I think it's going pretty well, but I want to make sure that I'm doing it the best possible way.

I have made created the surface pictured below and would be happy if you could open the attached creo file and review my model tree and the way I have modelled the surface.

Is it looking fine?

Would you have done it in another way?

I hope I can teach a thing or two if I haven't done it quite the best way.

Best regards.

I'd say you did your homework quite well!

Thanks. That's good to hear.

there is a 3 sided patch to be solved in different way, but in general good job

from perspective surfacing is the way of solving 3&5 sided boundaries, advanced fillets and complicated surfaces transition

some of them are discussed among my tutorials on

http://proe-warsztat.pl/en/tuts/tuts.php

Thank you.
So three-sided boundaries are best to avoid in general?


I have tried to make the three-sided boundary I had, four-sided.
Does it look better?

I'm trying to work this feature as a practice session. This really is a bear to deal with and is probably the most crucial feature in the design. Its the little things that usually are. But I will add how ID guys hate true arcs preferring C2 Continuous rounds. I can see this best treated as a sweep using a spline. Determine the origin string at the bottom of the troff and using the curves on the surface as guide strings (divide the circle into 2 for 2 separate strings).

I'm glad I don't need to do much surfacing with core Creo.

BTW, I hope that window doesn't need to be rolled down

You can easily judge the quality of a surface with help the "Shaded Curvature tool"!

I heard you guys like practicing surfaces.

nice example of 5-sided boundaries

below, tutorial discusses how to slove them

p.s ISDX in Creo 2.0 gives user much more control over N-sided patches than it was possible before.

Thank you for those tutorials,these are very nice.
