creating surfaces from lot of xyz data
 
my precedent message was in fact a part of a bigger problem : i have to import lot of xyz data points (a car)(this is ok) but then i have to make a surface representing the car with all of these points... if someone could help me in the way of doing this... PLEASE, PLEASE, ... HELP

Re: creating surfaces from lot of xyz data
 
You would probably have much better luck importing this data into a CAD program (I am assuming you have access to CAD at your university). You should then be able to create your surfaces, then export to some format compatible with your grid generator. Complex surface creation is problably best left to tools that were made for that task, i.e. CAD, then let the grid generator map to this surface.

Re: creating surfaces from lot of xyz data
 
Hello Rolando,

For the first problem, it sounds like there might just be a formatting error in your input file. In this case, it would be easiest to diagnose, if you could forward the file to your support contact.

For the second issue, it is important to know if the coordinates are structured or not. If they are, the answer given above is applicable. If not, you would need to either generate a triangulation of the points and process this into a set of surfaces, or you could try to attract face meshes to these points and then export surfaces from these face meshes. In any case, I believe the best course of action would be to have your support contact take a look at your data.

Best regards, Allan
