Hi Sundar,
Last time I dealt with iv exports from Catia, it turned
out that the exported file contained 5 levels of detail.
If you manage to remove the highest LOD, you can probably
cut datasizes down by a half. Alternatively, only keeping
the highest one, also tends to halve the datasize.
In my case, I opted to keep a medium level of detail, for
an even bigger data reduction. Having said this, I must
warn you that the lower LODs from our Catia exports showed
mangled geometry though, due to incorrect mesh simplification.
We did all this 3 years ago, and I do not know which Catia
versions we dealt with.
