Is it possible to calculate the vertices and edges needed in order to create a 3D model from a 2D isometric image?
Using an isometric grid, we can as far as I understand, simulate the z-depth. Is there enough information to create the rest of the model to 3D if we set certain constraints on the model, like being symmetric?
I created a drawing using an online isometric tool
From the gif above, we can see that some planes are missing.
Here is a more complex isometric drawing I made that I would love to convert into 3D (at least fill in the missing planes, and have a symmetric model)

Here is a similar question: Isometric Drawing Tool: Converting 2D information to 3D. The difference is that question linked to asks if it is possible to create a 3D model from a front-view of a 2D model, but it is not possible because depth is lost.
