Control points in surfacing

New member
Hi all,


Can someone show me how to create control points on a surface? I tried many times, but without any luck. I would like to use control points to control the smoothness of the surface I created.My verision is WF2.0


Any feedback will be appreciated.

Hi,


Are you talking abt control points in Boundary Blend???.If yes I can create an example and show it to you.

Control points on a surface works ok but not so great
compared to Alias Studio or Maya like tools and functions. for example
you can make a face in five minutes using Alias and or Maya. However
tweaking internal control vertices inside Pro/E is either normal to a plane or
normal to the specified surface and movement is awkward at best. To boot
you can not add internal control vertices (make the mesh more dense) in a controlled
environment. To boot 2: you can not grab two specific control vertices.
You can however grab a chain and or even one and move it so other local cv's
move with which again is very odd for control.



Maybe if I elaborate here with examples Pro/E programmers will get the picture
pun intended.



Busy today though...




Try this: Export some 3d surface from Pro/E and import it
back into Pro/E and while redifining the surface (use the pencil) to
modify using CV's. Cool eh?

Hi,


Agreed that surface option in proe is bad.But we have created some quality surfaces on proe .Finally I came to a conclusion that If you dont need A class surface then you can get any complex(obviously realistic)surface in proe allthough it is tedious.


I completely agree with you Design-Engine.

Thanks Design Engine, for your comments.


I really hope that PTC can do something about it, on surfacing, as I am a new beginner, I don't find it very user friendly at all. WF3 ?

You got to be kidding... Maybe I miss understand or maybe you never used
surfacing before in another package. Pro/E surfaceing is quite user
friendly, easy to learn and offers a hi-quality tool compared to other packages.


What packages have you used surfacing on? deepakbhat_nie might be working on automobile surfaces? As far as A-Class surfaces go, be careful because .05 percent of designers even
know an A-Class is and to boot the ones that do .5 percent of them even used a
tool that can beat Pro/E in terms of A-Class definitions.



Compared to Alias?



Both do A-Class surfaces.

A-Class surface in Alias is lighter geometry but that is it. Maybe
one less ISOPARM and Pro/E can be a little misleading because there is not a
setting to display isoparms as Alias Studio defines it.



Pro/E surfacing is Bad ass and I could write a paper on differences between
Alias and Pro/E in terms of quality of a surface. Alias can make a
higher quality surface yes. Usability? I take Pro/E any day
for speed and proving form. Alias you get to remodel the damd thing
if you want iterations.

Hi Bart Brejcha,


You got it right I have worked on automobile styling surfaces.I have never worked on A-class surface And we care a least abt A-Class surface in India(Except when doing the job for US

)As it simply adds to the cost. thank goodness that there is some one who says that surfacing is good in proe as I thought that i was the only one who appreciated Proe Surface option(Obviously incluging ISDX).
