TTSD-25782

An issue that would have caused certain previously imported shapes in the shape catalog to be incorrectly cleaned has been fixed in Tekla Structures. The affected shapes typically have had holes and have been imported to Tekla Structures using a version prior to Tekla Structures version 2018i, and then cleaned in version 2018i or newer using the Shape cleaner application. The incorrect result could be seen in the 3D view as missing faces on the cleaned shapes.
