That is to say, more than one closed shape on the same plane.

Is it possible? If so, how?

Thanks much in advance

Do you mean multiple extrusions from one sketch?  This is certainly possible.  After your first extrusion, right-click on the sketch and select Share Sketch.  This makes it available to be used by further features.

If you just mean multiple extrusions from one work plane, then there is no limitation on the number of features that can reference a work plane.

If you can't figure it out - attach your file here.

works like a dream - awesome! Probably my biggest peeve since I started.

Only thing, option is not available in some cases. Why is that?

Thanks again

Joe

Attach file here that exhibits this behavior.

Not sure how well that will work - it depends on which level of the hierarchy is active. Not a major deal, as I can just click around until the right object is active.

Just curious - what is the logic behind this "consumed" sketch business? Surely autodesk don't think that most people will only have one extrusion/revolution per plane?

I don't follow the logic of your statement.  Attach example file here.

Are you really referring to sketches?

according to http://wikihelp.autodesk.com/Inventor/enu/2012/Help/0073-Autodesk73/0308-Parts308/0353-Part_fea353/0...

"For parts, surface features and work features are automatically consumed by default to communicate feature dependencies." - What do they mean, feature dependencies? Most of the time, I want to draw separate features on the same sketch. Why is it that by default they are consumed?

I can post if you really want, how would you like me to package? Zip?

Go through this paper

http://home.pct.edu/~jmather/skillsusa%20university.pdf

go through this tutorial (the sketches are already done (see attached) - you might start a new part file and see if you can create them from scratch

oops, here is the file attachment.
