Hi everyone, any ideas or su plugins for this?
Could you please tell me how this will look when you convert it to 3D?
If you give a good answer (that is, you can figure out what exactly I drew looks like in 3D), then it might be possible to write a program in Ruby for 2D>3D conversion.

@dezmo hits the nail in the head. Generally a 2D representation of anything does not contain enough information for an algorithm to determine what the thing would be like in 3D. SketchUp has the MatchPhoto function that can help creating a model from a perspective photograph with help from photogrammetry but reading the photo still needs a human.

Hi, there is a plugin that converts 2D to 3D developed by one of VBO workflow’s users. Users must assign tag (or material or give a name) for every 2D object before converting.
Here’s the demo video
Why do you need a plugin for such a simple task? How will you use what you create with it?
I would like this plugin to enable this functionality to quickly generate a 3D model when having three views.
I see. I don’t know of any extensions that will do it automatically. Except in the case of a very simple shape like you show there is generally not enough information included in the 2D views to generate a correct 3D model without some decision making that is beyond what a Ruby script can provide.
Here’s a simple example. How would you make a 3D model of what I show below even manually? How deeply are the doors and windows?
There’s not enough information in these 2D views to answer that question.

You are right, the one I mentioned is only for simple shapes. I need to consider more complex cases.
