Disappearing workplane in Solidworks.
I seem to have a problem when sketching in Solidworks 2011. When I am in a sketch and hover over another existing surface in the already present model. this plane/surface becomes active direct and the sketch I'm working in becomes inactive.
A new sketch is automaticly opened.
It must be something in the options but I can not find it.
This is turning me a bit frustrated.
Anyone with helpfull advise.
I do not want to re-install SW (yet)
