Not sure if this is the right forum section for this but I've got some questions regarding surface modeling.
We're working a lot with scanned objects in STL file format. Having never worked with surface modeling before, our usual work-way is to create section curves on the facet model. Then use those curves as a reference to model the part. And use GOM inspect for a final surface comparison check.
To my understanding the more accurate way is to get into surface modeling (specifically for 3D-impellers).
Usually I can get a lot of information from youtube or google regarding methods I haven't worked with yet. There's not much I can find about reverse engineering STL files though. Is this something that can be self-taught? And if so, can anyone point me to any in-depth guides / tutorials explaining how..
