I am trying to open a dgn file in ArcGIS Pro 2.1.2. The dgn file contains 3D "b-spline surfaces" & a "smart solid/surface”, however the b-spline surfaces do not display at all on import. The smart solid/surface do display as a series of polylines.
I was wondering if there is a work around for this, or if there is recognised list of CAD geometry types that can be imported into ArcGIS Pro? Any help would be much appreciated.
