Thank you for your great ideas. I will try every suggested solution and inform you which fits best for me.

@pbacot: You understood perfectly what I wanted. This is the wished output. Thank you!

@alvis: Thank you for the Artisan hint. I will give it a try.

Thank you all for your help.

dear Pilou, thank you for your quick response. What you said is quite interesting for me (since I wasn't aware of this possibility), yet it is not exactly what I'm looking for.

Important for me is the top of the button, in a way the "pit" for your finger. The user thomthom develops a plugin that is able to do what I want (compare http://sketchucation.com/forums/viewtopic.php?t=32810). Unfortunately his plugin isn't yet released. So I'm looking for a similar solution.

dear Tig, thank you for the hint. I will keep that in mind, when using the "follow me" tool.

Hello there,

I would like to have a Bezier surface in Sketchup 8. Unfortunately I don't know how to get it.

For better understanding I have attached an image showing such a surface.

.

My aim is to design a button similar to a key on a typical keyboard (check the attached image).

I think to solve this issue one has to combine the two figures, shown in the image below. But I have no idea how to do this.

Any help is appreciated!

Thanks!
