Sketch origin

[jeanpaul]

Do you know how to control the placement of the sketch origin (not the part origin).
I have some parts where sketch origins are not at the same place from one function to another but i can't start to understand why?
If i want to move the sketch origin in ONE sketh, what do I do?
NB: For me it is important because i use an export soft which use the @#% origin

I wish I knew. I have floundered about many times trying to change a sketch origin. The best I could do is change the plane origin in some cases.

This is one reason I take the time to draw my own "origin" in most sketches. I'll draw a couple construction lines as a "working coordinate system" and dimension/constrain w.r.t. that. Big bacon saver, it can be.

I tried to change the sketch plane and yes, it is doing something to my sketch origin, she had not moved but now she is head down... (and always at the wrong place)
I suspect some rules but cannot watch them.

Tools / Sketch Tools / Modify Sketch

This tool moves the entire sketch, you may be able to get the origin where you want it but I never tried.

When you created your sketch, you certainly have created relations (geometric or dimensional) to the origin (otherwise the sketch is unconstrained).

Just edit the sketch and modify or delete/recreate these constrains in relation to the origin.

Gildashard tip works OK, but first you have to unconstrain the sketch in relation to the origin. Then you can apply the modify sketch. When in the rigth position, create new constraints.

Thanks for your help, it is working!
