I have not this release. I'll install it. Thank you very much!

Another solution: set circle to 12 segments, it will work fine with R= 4,5mm and it decrease the amount of edges.

Thank you for the suggestion, Gaieus. I didn't remeber that I can modify Clip mapping. It's strange that in the file exported from SU7 I have the pic in the field Texture with Threshold 0.5 and in the file exported from SU8 there is no pic. When I put pic, I have to give a lower value for Threshold (0.1) to see correctly rendered image... Ok, but at least it works... Thanks!
