Converting 2D DXF Floor Plans to 3D Models in Unity

Hi everyone,

I’m currently working on a project where I need to convert a 2D floor plan from a DXF file into a 3D model in Unity. I’m using the IxMilia.Dxf Library to read the data from the DXF file, and I can successfully extract the 2D information, which gives me the layout of the floor plan.

Here’s what I have so far:

  • I can read the 2D shapes from the DXF file.
  • The shapes are represented correctly in a 2D plane within Unity.

The Challenge:

While I can visualize the floor plan in 2D, I’m struggling to generate the corresponding 3D models based on the extracted data. For example:

  • When I extract a room that should be represented as a cube (with front, back, top, bottom, left, and right faces), I’m able to see the 2D representation. However, I don’t know how to convert this data into a 3D cube in Unity properly.
  • I need assistance with understanding how to map the 2D coordinates and dimensions to create 3D geometry in Unity.

Specific Questions:

  1. How can I translate the 2D data from the DXF file to create a 3D representation in Unity?
  2. What is the best way to handle the dimensions and scaling when converting 2D shapes to 3D objects?
  3. Are there any resources, scripts, or examples that could help me understand this conversion process better?

Any guidance or suggestions would be greatly appreciated. Thank you!
