Center of imported sketch appears in random positions

When importing a sketch in the extrude process, the center of the sketch is always in any other point than the center of the sketch -- not even on the middle line of the sketch.
In this example I wanted the center where the red dot is, but I could not drag it there, or change its position in any way.
Is there a possibility to edit the original sketch and make the center be in the very middle of the sketch by some procedure?
Or is it something that can be done here, in the extrude, to move that center wherever it is needed?

Hi,

maybe it will help to add a construction circle to the sketch, which will form the "cover" of your sketch.

during paste, if you right mouse button and hold on the circle x, you can drag it to where-ever you want,. It should snap to areas

When you import a sketch, you're offered a lot of options to affect the import until you "commit" to keeping it. Scale, angle, and yes, position. I don't know where it gets the initial values for the scale and location, maybe it has something to do with mouse position? Unknown. You have to specify a scale and position the sketch before you accept the thing. The key thing I have learned is to try to make sure the sketch I'm importing is completely defined (no weak dimensions) and I usually try to have a set of centerlines or some such features that I can use to position the sketch easily.

Scale is a weird one, or so I thought, until I found it very useful for importing geometry so I can engrave our company logo onto stuff. I can scale the logo to the appropriate size for the surface I'm going to inflict it upon.

Add a csys to the sketch when saving for reuse (import). Place it where you want the placement handle to be on import. With the csys present it is easy to drag the handle to the csys using the method disclosed by @StephenW .

An example of this is shown below.

PS

The placement handle is sometimes in the center of a sketch on import by default. It depends on how the sketch was constructed/constrained when saved.
