Controlling where copied Sketches go

Thanks for all who helped me move my sketch within the sketch. That was
great. The reason that I needed this help was because I was copying and
pasting a sketch into another sketch. I needed a sketch from later in
the history of my part to be pasted into the sketch that I used to begin
the part. When I copied and pasted it, it turned around 180 degrees and
moved in relationship to the origin. I don't seem to see any way to
control the location of my sketch when I do the copy and paste. Does
anybody know how to do it? Again this is SW 2003

 

If you copy the entire sketch from outside a sketch, and then place it
using the feature manager to select a plane, it should line up the same as
the original.

Part of the problem with flipping 180 deg is that it depends on whether it
is coming from/to a plane or a flat face. Each plane / face has a normal
vector. If you sketch a rectangle on the front (XY)plane and extrude in
the default direction (positive Z), the XY plane has a normal that goes in
positive Z, but the face on the XY has a normal that goes in negative Z.
If you move a sketch from the XY plane to the face that is on the XY plane,
the sketch will flip because of the difference in the normals.

If you're lazy, you can flip the sketch by changing it from XY to face to
XY to face again.

Or you could just use the Modify Sketch tool which allows you to move,
rotate, mirror and scale sketches.

good luck.

Have you ever tried convert entities. I know that this isn't always
possible whith the description it may have been. Start a new sketch and
select the old sketch hit convert entities. This will tie the sketches
together yet they can be on different planes. The only problem is if you
have to move them to a rotated plane or surface or have them offset.
