solid from facets ?

Hi there, can anyone help me? I want to obtain a solid model from a facets
feature....please!!!

The technology to convert a faceted solid into a feature-based model does
not exist in Pro/E. It is possible to convert the cloud of vertices into a
featureless surface model using Pro/SCANTOOLS, but don't expect it to be
easy.

Generally speaking you must model it yourself.

The steps below will give you a quilt feature. You can try to
Create>Solid>Protrusion>Use Quilt to get a solid. However, this will
only work if all the edges of the quilt are closed. Also, it probably
won't work if you have intersecting or self-insecting surfaces in the
quilt.

You can try to correct these issues by creating, merging and trimming
surfaces, but this can be EXTREMELY tedious. Also, the only thing you
really gain by going from the original quilt to a solid is the ability
to calculate volume/mass.

You probably would do it that way if 'facets' data were iges surface data.
However, Maurizio explained in a private note to me that this was an STL
file which is why he refers to facets. In that case, the steps I described
will produce a single import feature solid which can be assigned a material.
That will allow doing a model analysis of mass properties, pairs clearances,
etc. You can also measure distances, curve lengths, radiuses. From that
analysis, you may be able to reconstruct the part. I have the feeling,
however, that he was expecting more, i.e., to retain surface patches,
parametric features, dimensions, etc. None of that is contained in the STL
file and cannot be reconstructed on import.
