IGES import - exactly which IGES entity types (and forms) are supported?

[BobDuke123]

Dear all,

I had some success transferring geometries, generated with an advanced math software, to Inventor using IGES files containing Manifold Solid B-Rep Object Entities (Type 186) (see the specification IGES5-3_forDownload-1.pdf). Now I would like to include several Type 186 entities into a single IGES file and form the geometrical unit of these (and them), for which the IGES Boolean Tree Entity (Type 180) seems to exist. I'll do some trial-and-error testing, but it would be very helpful to have a (reliable) list of all IGES entities the Inventor IGES import function does or does not support (like these: Transcendata, MoldflowInsight). Unfortunately I could not find such a list anywhere.

Could someone from Autodesk provide such a list?

Another question: Are the IGES import/export functions of Inventor written by Autodesk (and/)or are third-party libraries used? If the latter, which ones?

Many thanks, Bob

Hello,

Trial-and-error tests showed that Inventor's IGES import filter does not support the Boolean Tree Entity (Type 180) – a pitty. If someone could post a list of all IGES entities the Inventor IGES import filter does or does not support, it would still be very helpful.

Thanks, Bob

Welcome to the forum!

I've never really worked at such a level with iges files, so i got curious.

If you open "iges_x64_vc10.dll" in "C:\Program Files\Autodesk\Inventor 2014\Bin" with wordpad you'll get a lot of gibberish, but somewhere near the end of that text there will be a collection of the things you mentioned.

I will say at once that i have no clue if this is really what you want, since there is a lot of "Boolean Tree Entity" in there, but no mention of "type 180".

Maybe someone with more knowledge of this might pick this up, i'm still curious but don't work with iges enough to invest more time.
