I want to change the point threw a prop rotate.

If I understand it right this is the “origin”. But if I try to move the origin the object is moved. How to do?

torulf, i hope i've understood and i don't give you a wrong answer : try to "display origin" and open the joint editor : you will be able to move the origin of your prop without moving this prop
.

Yep, that's what you need to do.  In the Joint Editor, select "Center" and you will see 'Origin'.  This changes the origin of the joint - which controls the coordinate system about which the object is rotated, translated, scaled.

It’s not work. If I use the move origin 1 the ski is moved. At the joint editor only rotate 2 is visible and they do rotate the ski. There are also numeric tables 3, XYZ for center point and endpoint. It’s for canter point moves the ski the one for end point dos nothing.

As you have the picture shown: Move the green cross hairs up to the hip, about where you want the pivot point to be. Check the pivot by using the x-rotation dial. It might take a bit of trial and error to position the cross hairs exactly where you need them.

As nickedshield notes, the green crosshairs represent the origin and the red crosshairs represent the endpoint.  The endpoint is mainly used for IK and PointAt.  When you get close to the center of the green crosshairs, you should see a circular 'target' mouse cursor.  Click and drag then to move the crosshairs.  If you want real accuracy, set the Document Window to display orthographic views.

I have seen the green crosshairs and find the circular 'target' in the centre. Then I try to move it with the mouse I only move the ski. I have also unmade the parenting with no changes.

Its still not works.

With a normal un-parented prop, to move the origin without moving the prop, the prop needs to be in a zeroed state. Set the Tran and Rotate dials to 0, set the Scale dials to 100%, only now move the origin.

With a smart prop it's diffrent. I think this is how it works, but I might be wrong. I think it is actually the origin of the prop that gets parented, so changing the position of the origin relitive to the mesh  will of necessity change the position of the mesh relitive to the item it is parented to.

I don't know of any way to move the origin of a smart prop and keep the prop in the same position relitive to its parent. I think you will just have to move the origin then reposition the prop.

On the subject of moving the origin, its usually easier to use paramiter dials than the Joint Editor, but after turning on 'Display Origin' in the Properties you may need to select the GROUND then reselect the prop in order to refresh the pallet and allow the new dials for the origin to show.

If the prop moves when you change the origin the only way is to export the prop as *.obj and import it again, then you will able to change the origin and the prop will not move.
The reason of this behaviour is that the prop was intialy loaded at some other place and then was moved, scaled and rotated to where it is now.
When the prop is exported is exported with the actual vertices coordinates and not with the who knows where vertices coordinates, when imported again the position in Poser will match the obj file information that refers to the actual position.
