Hi Kühl, tusind tak... you just saved my day... I use a different version of CPS thou, but somehow I figured it out with your help... it was a bit tough thou since it had become quite some model, and not only an cube... but I have learned a great deal by your video tutorial... so now I can work on one half instead of 2... thank you very much... next time I start working on a model with CPS I will start it, as you showed in the video... much easier to work with... regards Strarup
