Move and rotate body at the same time

ebunn3 — Tue, 02 May 2023 14:15:06 GMT

Hi all,

I've put together a script called "moveMultBodiesinList" that I would like to use to translate and rotate a body(s) with. When you run the script I posted below with these variables: moveMultBodiesinList([body],90,20,0,0,'XY'), it will perform the rotation but not move. If I set rotation to 0 it will move the body using the x,y,z values.

Can someone tell me why this script will only work for just a rotation, or just a move, but not both at the same time?

If you copy and paste the code below into a python module and run it you will see that it rotates the selected body but does not move it. If you set the rotation to 0 and run it you will see the translation occur.

Thanks for the help!!

Re: Move and rotate body at the same time

Hi @ebunn3 ,

On line #130, when you use mat.setToRation() it will override any previous settings in the matrix.

You might need to use mat.transformby() instead, in order to rotate what yo have previously defined in the matrix, like so:

if angle != 0: mat_rotation = adsk.core.Matrix3D.create() rotate = mat_rotation.setToRotation(angle, rot, ctr) mat.transformBy(mat_rotation)

Hope this could help.

The TransformBy didn't really work for me since it also transformed the origin in the rotation but I was able to solve my issues by realizing that I could set up two separate Matrix3D objects, one for the rotation and one for the translation.

I do the rotation first followed by the move and it works the way I wanted it too. Thanks. Code is below.

hi @ebunn3 ,

The order matters, so you could transform the rotation matrix with the translation to get the result you want, like so:

if angle != 0: mat_rotation = adsk.core.Matrix3D.create() rotate = mat_rotation.setToRotation(angle, rot, ctr) # mat.transformBy(mat_rotation) mat_rotation.transformBy(mat) mat = mat_rotation
