Topic Description
Hello everyone,
I am trying to change the default pose of a manipulator composed of several parts. However, since each part is defined as an independent Xform, I cannot move them while maintaining their relative positions, even when selecting them all together.
I understand that defining them under the same Xform would allow for such an operation, but restructuring the Xforms is a tedious process.
Is there a way to move multiple independent Xforms while preserving their relative positions?
Thank you!
I found that after selecting multiple Xforms, there is a “Group Selected” option in the right-click menu. Using this, I was able to move the objects while keeping their relative positions.
But now I have a new problem. I cannot rotate the grouped objects around the position of a specific object. After moving the Xforms while keeping their positions, I want to rotate them while keeping their arrangement based on a chosen Xform’s position.
Is there a way to do this?
Hello All,
I’ve continued working on it since then, and I’m almost finished.
However, I can’t manage the final rotation.
Currently, I’ve progressed form the state shown in Image 1 to that in Image 2.
Image 1:
Image 2:
My goal is to reach the state shown in Image 3.
Image 3:
I need to rotate around the final arm object’s coordinates, but other objects get left behind (Image 4).
Image 4:
When I try grouping them, the group’s coordinate origin is different, so I can’t achieve the desired rotation (Image 5).
Image 5:
Is there a way to group these objects so that I can perform the rotation as intended? If not, I’m considering editing the original CAD data, but then I run into a separate issue.
