Hi - thx for fast help - and yes I did a lot of things in a complicated way during the last weeks. But it helped to learn more about all the editors. My first model took several days. The last one I created, took about 3 hours Both nearly equal work.

Since the models are done, I just startet with my first own lite-C scripting besides the tutorials

So the code came just in time.

Cheers

Ditje
