IF 3D CAD OBJECT DEFINITION GIVES YOU A HEADACHE... TRY 3D DOCTOR
The problem…..
B-rep modeling (boundary representation) is
presently the most efficient tool for the
representation of 3D CAD objects (solids or surfaces).
There exists today a consensus around the
STEP standard for the exchange of topological
entities (solids, shells, faces,…) and geometric
entities (circles, cones, Bezier, Nurbs, B-spline,
cylinder,…), but there is no accepted standard
to check if a definition is valid or not. The different
modelers, and even the different functions of the
same modeler, have different tolerance values
regarding "defective definition". For instance, a
badly defined face with an open trimming loop
will be displayed as curves and won't be shown in solid mode.

the solution…..
3D DOCTOR is the most productive tool in the market that allows the automatic correction of some of the flaws you may encounter. This will enable a greater number of functions and modelers to accept the validity of the definition of objects without changing their geometry.
and more…..
3D DOCTOR offers also some operations to complete or modify the definition e.g. fill up holes or delete some trimming curves.
