@box said: Works for me on FF. that works here as well... cheers Box and nice work DanYHKim and co...

Unfortunately, no 64-bit SU available. Also seems that 64-bit SU is fairly unlikely to arrive soon. When a renderer runs in context of SU, you will limited to 32-bit address space, even if you have 64-bit OS and Largeaddressaware is in use (SU8 maintenance 1). Largeaddressaware does help, but if your scene size is great enough, only feasible option is to use a external (to SU process) renderer, then you can benefit truly from 64-bit processes.

Edit Group then paint your texture. Earthmover has a tutorial he posted lately showing a good technique in UV mapping using Artisan and UV Projection.

WhiteOwl77 Unless there is a significant model difference ,I did test my suggestion with cases of sphere and cylinder intersections and it worked very nicely. Can you post your model or maybe a section thereof. I think you are making things more difficult for yourself

He posted the file to me. It was impossible to attach here as it is 9Mb+. To me, the intersection seems to be pretty smooth (regarding SketchUp1s nature to segmenting everything) but if really smooth results are needed, you need to make everything so detailed. The arch was made of really high segmented arcs, the dome way made of a really high segmented arc as the face to be lathed however the circle around which you lathed it is still the default 24 segmented circle. Such an intersection will always be somewhat segmented but if you are ready to sacrifice workability for smoothness and precision, you need to do it including all elements of the model.
