How to setup scene for Isometric workflow? In order to import 2D ISO image to make it in 3D You know we can make 2D isometric renders of 3D images, right? I want to do the reverse; I import an isometric image and want to use it to create the 3D model. An illustration of the work I'm trying to do, I've setup the camera (rotation xyz 60,0,45) and I've created some cubes to work with to see in wireframe:



My problem is, once the correct camera setup is done, the grid isn't set up correctly. I mean that the height of 1 is not corresponding with the grid and the closest I have is 0.81673, you can look the image below. The cubes aren't seized precisely and when I Ctrl+move the increment is 1 and not of the height of the cube;



My questions;


How to find the correct size for my cubes?
How to setup the world to work with that isometric height non equel to 1?
What is the best workflow to achieve the result I want, recreating in 3D a 2D isometric images (moreover if I'm going the wrong way) ?


Thanks in advance
Step 01
Blend file - Dimetry

Set camera Dimetry (54.563/0/45) with dimension of your ISO-image
Increase camera dimension on Y axis *1.150
Add your image as Camera Background Image
Build your models and save

Step 02
Blend file - Isometry

Set camera Isometry (60/0/45)
Add Empty
Link Collection (or Scene) done in Dimetry
Parent link to Empty
Scale Empty on Z axis 0.81673
Render

Like that you can anytime to switch into correctly measured models in Dimetry, but just by opening Isometric file re-render for final output.
