Sketch Reuse

[eike.scholz]

I am trying to design some basic structure using a simple L-profile that later might be changed into a simple square tube profile or some other more complex aluminum extrusion profile. I am trying to have one sketch and with multiple extrusions. Each extrusion will be moved and rotated around and may differ in length.  If I change the single reference sketch all derived bodies should be updated too. But I do not get it to work. I can do exactly one extrusion for a single sketch. After that the extrusion dialog window on the used sketch does not let me specify a extrusion length and the visual interface is also gone! 

Exporting the profile into a separate assembly file and the importing it as assembly works, but it seems to be overkill to create a single assembly file for just one sketch. Is there any simpler way to make this work?

there is no other way to do this that I can think of outside of creating a separate external design, and inserting it multiple times.
