IGES Export Warnings

Message Means
Geometry omitted by exclusion of Entity: No./No. Entities are omitted from the IGES file because the indicated entities were excluded and there is no alternate entity type to represent it. This usually occurs only if the copious data (type 106) or point (type 116) entities are excluded.
Degenerate (zero radius) arc omitted Promis.e DGN files can contain zero radius arc or circle elements. Because the IGES specification prohibits these entities, they are not exported to IGES.
