What IGES version does Nastran for Windows v4.5 support?
N4W 4.5 is not concerned with IGES versions. What is important is that you have entities that are supported by the program. To see what is supported by N4W, please see section 7.3.4.1 Supported IGES Entities from the N4W Online Help. I have two models in two different FEMAP neutral files. The two models are to be merged into one model. However, there could be a conflict in ID numbers (FEM or geometry entities). How do I merge the models so that this doesn’t happen? If there is a conflict with duplicate IDs between entities in the neutral files, the entities in the second neutral file to be imported will overwrite any entities in the first neutral file with the same ID. To avoid this, simply use the ID Offset in File/Import/FEMAP Neutral under Model Merge Options. Use an ID Offset that will ensure that IDs in the second neutral file will not conflict with those existing in the first imported file. All entity IDs from the second neutral file will be numbered with this offset.
