Either there is a problem with Sketchup or there is something I am missing.
Step 1. I create a cylinder (shaft) component which is placed 30degs to the red axis along a construction line.
Step 2. Then want to dynamically rotate the cylinder about the red axis. Accordingly, I open the component and set the red axis along the construction line which is the centreline of the component. The green axis is along the normal green (or outside of the active) and the blue finds itself perpendicular to the cylinder face.
I have also placed a mark on the cylinder face so that I can see that it has moved.
PROBLEM: When I enter a rotational value in the RotX attribute, the component does not rotate along X(red) axis, instead appearing to move around the green (y) axis. Furthermore, the Y axis shows a value of -30 despite having set the axis per step 2. Why is this so and what am I doing wrong?DynamicRotationProblem.skp (54.3 KB)
