Only discovering SketchUV now, this post more than becomes relevant. Definitely following.

It is good if SU has Snap Tools like Auto CAD or any CAD Software.

oh my god.. honestly i think not really a good idea.. that wouldn't be sketchup anymore imho.. 😄

Pilou, I will have to try this and see how this works... and if I can get it to work as I hope it might. Again... thank you for the link.

For this you can use the shortcuts "l" (=line) and "a" (=arc) without the need for a plugin.

edit:
you can find an overview of the standard shortcuts here:

I already have both on a shortcut. What i basically wanted was something i can program 2 commands into one shortcut. It sounds stupid i know, but it would be really useful for me.
For Example: You have the letter X as a shortcut. With that you can put in circle and rectangle in it, so by pressing it once.. it will be circle, pressing it again its rectangle, pressing it again.. its back to circle. Call me lazy, but i don't work with toolbars, everything has a shortcut, and 99% of my work is speed-modeling.
