just select the sketch you want and do a convert entities.
you would probably get more responses by "moving" this discussion to sketching forum.
try slecting 2 entities from driving sketch.
in my example jpeg i chose the arc and vertical construction line to create my derived sketch(s).
(no need to create plane one will be created automatically)
after which, i edit the plane that was created and change how it was defined.
this is all i know, there is possibly a better way.
If they repeat the Top 10 Enhancements process again next year, vote for giving the user the ability to control the orientation of a plane normal.
In the old days, the work around was to put a plane at 90 degrees to the plane you want to put your sketch on. Change the plane of the sketch to the perpendicular plane and then back again. Usually within a couple of tries it would end up in the right orientation. Charles Culp recently came up with a new and improved work around. Make the plane you want and put a sketch on it with three points. Use the three points to define a new plane. If you get the correct orientation, you're done. If you don't, change the order in which you pick the points.
Makes me wonder if the programmers ever use this command after developing it, or do they
figure all people mirror only when using derive sketch.
But thanks for the help guys.
