Maybe handy for in future versions:
If I am sketsching a installation in Sketchbook (for aterwards to convert to Solid Edge), I need to start directly in the correct scale. So for bigger sketches it's realy not practical how the app now works. There is no possibility to zoom out once you have started your sketch, for example if you are drawing something in the right of te screen, and you want to ad something new to it, you can not zoom out. Maybe make it possible to ad some new 'white paper' when you started a sketch?
