Hi everyone
This may not even be a Pro/E question, but I'm bringing my final result into WF2, so hopefully someone here can help.
I have 2 STL files of an object, which I am trying to replicate in Pro/E.
The STL files are huge (~1.7 million triangles each) and the object which was scanned is a highly irregular shape.
I intend to do this by developing cross section curves of the shape, and then using ISDX or Pro/Surface to develop surfaces from the cross sections. In the end, I want a closed volume that would just envelop the scanned shape.
Now, working with these STL files is really tough. The sheer amount of data involved makes work really slow. And I'm doing this work Pro-Bono, so I want to be able to shrink the data down somehow so that the project can get done in a reasonable amount of time.
Now for my question:
Does anyone know of a way I can extract points from the STL which are on or within a certain distance from a particlar plane in space? If I can get relative x-y coordinates of these points at some regular interval, I'd be able to work with this data much more efficiently.
The research I've done on the web tells me that most (all?) of the commercially available STL editors require manifold (closed) surfaces, which I do not have. I tried using the Restyle tool on another computer with a license for it, but its the same deal. There are holes-a-plenty in this scanned data.
Thanks in advance
