Hello, I compare this function in the sketchup with similar functions in 3DMAX. I find that the direction of Z axis can be adjusted in 3DMAX, while the Z axis in the sketchup can only be adjusted automatically by adjusting the other two axes. In fact, the operation of 3DMAX is more suitable for modeling in many cases (for my own situation). I don’t understand their principle. But I hope the sketchup can do better than 3DMAX in the future.
