How to create a sculptured surface from a cloud of points in space?

How to create a sculptured surface from a cloud of points in space?

How to create a sculptured surface from a cloud of points in space?

(OP)
Hi,

I am completely new at ABAQUS so please be patient. I have a "cloud" of points in space(about 50 points).  The points were retrieved using a coordinate measurement machine.  The machine took these points from a part of irregular curvature/surface.  I am trying to model the original part using these points along with ABAQUS.  Thus far I have inserted all 50 points in ABAQUS. How do I connect the points to form a sculptured/curved surface?  Also how would I extend this surface once developed?

Thanks

Hi

I assume that you have imported the points into ABAQUS/CAE?  I don't have a lot of experience with CAE myself, but I don't think it has the surfacing tools that you would need to create the geometry.

It would probably be better to take the points into a CAD program so that you can generate the surface, then import the surface into CAE for meshing.

Hi,

Thanks for your help.  I have took your advice.  I have been trying to create a surface using unigraphics.  I am also a first time user of unigraphics.  I have tried just about evrything within the documentation of the program.  It seems I get very close to createing the surface and then I cannot complete the last two /three steps.  Do you have any insight on how to do this on unigraphics NX3.  Also can a model completed in NX3 be usable within ABAQUS

Cheers

Hi Paul

No experience of UG I'm afraid, only Pro/E and Solidworks winky smile.

You might be better asking in the UG forum http://www.eng-tips.com/threadminder.cfm?pid=561

As for getting the surface into CAE, you could just export either an ACIS (.sat) or IGS file out of UG and import that into CAE for meshing.
