I have been trying to rotate my model (any model actually) in order for it to be baked and be able to run Make2D directly from Top view.
According to this Wikipedia article, there are 2 rotations to achieve Isometric View,:
For example, with a cube, this is done by first looking straight towards one face. Next, the cube is rotated ±45° about the vertical axis, followed by a rotation of approximately 35.264° (precisely arcsin 1⁄√3 or arctan 1⁄√2, which is related to the Magic angle) about the horizontal axis.
OK, your angle is wrong. I did a quick experiment and determined that the three lines you refer to (“101.54”), projected to World XY, become equal in length when the angle is ~54 degrees. As explained in the Wikipedia citation:
Which is \text{arctan}(\sqrt{2}), not \text{arctan}\!\left(\frac{1}{\sqrt{2}}\right):
FYI, here is the “test jig” I rigged up; I was intending to measure the angles between these three lines, then realized that they would be of equal length which is more expedient to measure:
Isometric views take me way back to mechanical drawing classes in high school, where X and Y lines were drawn at 30 degrees using a plastic triangle and T-square.
