How to change the plan of a sketch, but having the good orientation of the sketch

Hi,

I want to duplicate an existing sketck, with having a defining orientation of it.

So, to change the plan, I know how to do it, but a plane has 2 faces, and of course, SW makes a choice (when the program would have to not do it, without asking what face has to be choiced !!!), and of course, the choice is the bad one.

How can I get the "good" choice of face ?

And, btw, if any sketck, as any PRT and any ASM would have a local 3D frame, as TFlex has, it would be much more confortable - and much more logic, too !!! - to work with SW

Tx for your help

No one else has this question

If I want to symetrisize a part of a 2D sketch, I can't mirror about, with an axis previously defined in the PRT !!!!!

  Philippe,
  Can you post some images or your part or both?

I know this is really PITA some times but I generally orientation my plane/face in the required position (e.g. Front vs Back) and then edit the sketch plane and it works for me.

  Hi
  I tried to copy the sketch, one orientation of the source sketch, and paste.
  
  The other view, of the source, before copy and pasting : I get the same result !! The bad orientation in final

    Philippe,
    
    This has been a major pain in the *ss since as far back as I have been using SW (98+). There are some workarounds. If your sketch doesn't have any external relations you can mirror the sketch using Tools/Sketch Tools/Modify. If there are only a few relations then it is not too hard to remove them, modify the sketch, and then add them back again. The other method is more tedious and less well-behaved. Change the plane of the sketch to some other plane, preferably at right angles to the one you want, and then back again. Sometimes you have to repeat the process several times, but usually you can get it to flip to the "correct" orientation.
    
    Since I'm still running SW2010, I don't know if this still works in 2011.
    
    Be sure and vote for allowing the user to control the orientation of planes when the wish list for SWW2012 starts up. We were within a few votes of making the Top 10 last year.

    Edit: I'm wrong, as you no doubt already know from reading Waynes' replies to another of your posts. No need to vote for an enhancement, as the restriction of not being able to modify a sketch if it has external relations has been removed.

      Jerry, this limitation is fixed in 2011 sp4. If the sketch located with respect to the origin, you can still mirror. If sketch is located by dimension to an external reference, the locating dimension is not coped.

Yeah, not too hard:

Get your sketch,
Copy to clipboard
Open new part
Select the plane you want from configuration tree (top, front, side)
I do this step for fun "re-draw sketch entities" as sometimes if I bring something in from illustraitor ther are gaps on the vectors.
Then extrude your sketch so it becomes a part.
Save it
Bring it back in to your main assembly
And then move/place mate wherever
The delete the extrude feature of the part leaving the sketch
You may get rebuild errors; they are simply coincidents etc so delete them and you are done

It may sound long, but it takes as long as it has taken for you to read this!
Sweet
Lee!!!
