I work in the structural steel field. We us a cad program called SDS/2 by design data, it creates a 3D model of buildings. The software has a option of exporting the model in a *wrl format that can be viewed by a VRML viewer like cosmo or cortona (I am very new to VRML!!). The problem that were are having is the models are very large. The textures seem to have tearing to them, we have look at big models and small models but they all have the same problem. Is this a common prob. with these viewers? We have also tryed the view & models on different systems, I have even taken it home and I have the same prob. so I dont think its a PC issue (I have all the latest video driver) My system is a P4 1.8, 512 RAM, GeForce 4 w/128 RAM.
Is there maybe a plugin or something that might correct this prob.
btw I have tryed both viewers listed above. Any help would be great, T.I.A.

I've seen some of the VRML created from SDS/2 and I agree that it is
very large. Typically any VRML exported from a CAD package is very
verbose. The problem is with the models, not the plugins. However,
with the plugins there might be some options to set that could speed up
the rendering.

If you have the option to export CIS/2 (CIMsteel Integration Standards)
files from SDS/2 then you can use my CIS/2 to VRML Translator
http://ciks.cbt.nist.gov/cgi-bin/ctv/ctv.cgi which will create much more
managable VRML files. You can see lots of examples at

Thanks Robert Lipman,

I have included a clip of our options.. and I dont see the CIS/2. Does anything else look like it might work. SDS/2 will only give so much support for 3RD party software... so thanks for anything you can pass along.

I have found out that it does support CIS/2 so I will check that out, thanks again
