Neil,
>> I didn't know that r13 had a 64k limit <<
This is a limitation on all versions of 3DS up til now, so if you were
thinking about going back to ACAD R12 for this 64k limit problem, it's not
going to work. Don't forget that this limit is on the object level only, so
each object can not exceed 64k faces/vertices limit.
I have been doing a lot of IGES conversion to 3DS and I have an unlimited
number of levels in the geometry using a function like Facetres in ACAD R13 and
you can build some real nice detailed models.
BTW- Just to let you know, I relieved your message via E-MAIL you could have
sent it directly to me via the AMMEDIA Forum.
