Thanks! ☺

Hi,
In the following code, I draw cubes based on their x, y, z, width, height, length, rotation x, rotation y, and rotation z. But I have a problem properly representing the rotations. I can only pull off one at a time but not the others.

So no matter how randomly I rotate the cube:
-The 1st cube (leftmost) rotates correctly along its y-axis (yellow line) but not x and z;
-The 2nd cube (center) rotates correctly along its x-axis (red line) but not y and z;
-The 3rd cube (rightmost) rotates correctly along its z-axis (blue line) but not x and y.

It has something to do with the order of how I code the angles to rotate.
-The 1st cube rotate its y first, then x and z;
-The 2nd cube rotates its x first, then y and z;
-The 3rd cube rotates its z first, then x and y.

How do I use the take the rx ry and rz and rotate the cube properly on ALL axes? Somehow I can only make 1 work at a time.
