How to create a sculptured surface from a cloud of points in space? 1

[s89t3]

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 ;-).

You might be better asking in the UG forum

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.
