Hi Gaieus, thanks very much for reply. I've made all the steps as you suggested and it looks better, but still not good enough. [image: curtain1.jpg] Perhaps I will need to use the plugs as rclub24 suggested Thanks again for your help... Cheers Michal

@andybot said: I've run into that problem too. My solution has been to export from 3DSMAX as DAE file (Collada). That seems to import the geometries consistently for me into sketchup. thanks for reply.. I've tried the OBJ format, but it doesn't work for me.... I'll try with DAE format.. cheers Michal.

Wow!.. Great, great, thanks, you're very kind and helpful... cheers Michal
