OSDM offers productivity enhancements when importing IGES files.

The processor decides which curve is best for the trimming the faces. It first checks the 3D curve; if the result is unsatisfactory, it automatically uses the UV curve.
This option notes all the changes that exceed a tolerance during the healing and repair step. The 3D annotation, “This face has been corrected,” points to all modified faces. These changes can happen when:
Fitting a surface to trim-loops.
Recalculating a bad surface by approximation (= self-intersecting, with high curvature, degenerate).
To delete labels from an imported model:

Right-click to get the context-sensitive menu.
