Import from IGES

69 Views, 7 Replies

I finally got a big IGES file (17Mb) into Inventor. Now I am seeing all see
thru part and I notice in the browser there is a Construction folder. Under
that has group so I did the promote and picked the surfaces. It crashes
everytime so is there something I should do first before I promote the
surface to make it become solid? When I open IGES, I checked mark for Auto
Stitch and promote. It doesn't make any difference...Can one explain to me
because I have no experience with IGES or surfacing stuff?

Thanks,

As you apparently already know, IGES is a filetype for surface models. Inventor's Auto Stitch and Promote works great, provided the IGES surface is healthy. If there are miniscule gaps in the surface, it doesn't represent a closed surface, and Auto Stitch and Promote fails.



You'll need something like CADdoctor by Elysium to heal the IGES surface before importing it into Inventor.

Derek, have you tried to import and stitch in MDT? Can you describe the
parts in the file; curvy, simple, lots of them, etc.?

If you don't have any choice except to work with the file, I'd try MDT. The
simplest approach is to import and see if there are any obviously goofy
surfaces. If things look ok, try to stitch using the defaults (select all and
let it cook) and see what you get. Using the healer functions of the stitch
command may help get the remaining quilts to join to solids. If this doesn't
get you anywhere, manually segregating surfaces and stitching individual parts
may get you farther along.

I suppose asking the source to regen the model to a tighter tolerance and
giving you a .stp is out of the question?

Good luck with it,
Jeff

Derek,

Like you, I haven't had a lot of experience pulling IGES things in either, but
when I have made the attempt, it only sometimes worked. I had a choice of
Parasolid or IGES formats, tried the Parasolid style first (w/Xchangeworks and
MDT) and couldn't get a solid that would work properly in IV 6. I then went
back to the IGES file and directly pulled it into IV. Stitching and Promoting
left me a pretty smart IV part. I even got cocky enough to emboss "Femur" on
the human femur model, just to see if I could. It started out as a 6.5Mb IGES
file. Hope you got something to work.

Doug
