Recreating 3D Meshes in Shapr3D - How to?

Having trouble with rebuilding a 3D model from an imported mesh STL. I’m not able to loft sliced sections.

Any advice would be appreciated:)

Here’s the url to the STL:


@CEKuhnen made a great reverse engineering tutorial, this might help:

Thanks :blush:

I have been successful at rebuilding models from imported scans but the fan blades with slightly curved blade surfaces and other tricky geometry is very difficult for some reason. The loft function and using slices with hand traced spline doesn’t seem to work.

Is there another more efficient way to do this?
