Hey all, I am new here and just got my hands on Creo 3.0.
I have worked on SolidWorks over the period of 4 years so I know a few things about CAD.
What pushed me to start exploring creo was that I'm starting to have the need to work on laser scanned files, STL, VRML, IGES and SolidWorks has proven to be a real pain in the ass in creating or even worse, recreating weird surfaces. As far as it seems, creo isn't.
My question is simple - is there any way I can attach geometry to a facet feature obtained from STL o VRML files? I know I can edit, delete and refine it, but I have no clue how to sketch splines on it (or at least share sketch points with it). If it is possible, it would be nice if someone could at least point me into the right direction.
I have heard that reverse engineering extension does just this, but please note that I do not have any more spare money to throw away for extensions. It would be different if there was a way to try a free trial of this extension. Also my file has a few holes that are not small, so I doubt automatic surface creation would do any good, I plan on going manual in stead, so please.
Thank you for your time.
welcome to the forum!
I have not much practical experience with scanned data in production, but from the functionality point of view, the key points are:
Triangulated surfaces and analytic/spline surfaces (as used for Creo model geometry) are not compatible.
A high number of small triangles still does not make a smooth surface like a cylindrical or ball shaped surface.
You cannot use facetted geometry to sketch on, make it solid or intersect it with the solid geometry.
So what is the use of it?
Do we have some users on this thread with practical experience using those methods in production?
