Hi, I was wondering when we use dimetric projection, how much percentage-wise do the sides shorten or lengthen.

For example, if the object of projection is a cube, and after transforming the base, we want to use original dimension for the vertical length, what is the relation between a and a* (in percentage). In the second image the a* is somewhere around 90% of a's length. But if anyone knows if that's not correct, what should be a more appropriate correlation? 

Or to simplify the question. How much would a same dimension shorten/lengthen from z to x or y position?

You get to decide that all by yourself. 

So there isn't a precise rule about it? Developers decide based on if it's visually appealing or not?

I found this post on Adobe forums while looking into the subject:

There is an in-depth answer about dimetric projection and what are the dimensions we get when we use it. So if anyone's looking for something similar, I found it to be useful, so thought to share it.
