Topic Description

Detailed Description

I am intending to import 2D .DXF CAD files from my computer onto Isaac Sim such as a 2D floor plan but there seems to be an issue with the conversion of the DXF into Isaac Sim, it does not seem to import the file fully and correctly and only certain parts of the DXF file can be seen. Is there a fix for this or an appropriate conversion to assist with this?

Steps to Reproduce

  1. Press File → Press Import
  2. Select the appropriate DXF file within the computer
  3. Press the import button

Additional Information

What I’ve Tried

  • I have tried to import it directly but the above issue shows the file unable to imported correctly.
  • I have attempted to extract the coordinate data from the DXF and recreate the layout using debug_draw as well as USDGeom but it seems quite complex to recreate it accurately.

Hi @muhdhaikelbinyasin thanks for your question! Have you tried using the CAD Converter? CAD Converter — Omniverse Extensions It should support DXF files

Hi, I have enabled the CAD Converter extension within Isaac Sim extensions and I have been able to import 3D .STP files for example perfectly fine. However, when I try to import .DXF files, the above problem arises and it does not convert it well. Are there any additional steps regarding this CAD Converter that I have to undertake before the conversion.

@muhdhaikelbinyasin i am just another user, but one thing to know about Kit apps from my past experience is they don’t translate 2D splines from other packages/formats even through CAD converter. if the floorplan has anything other than 3D meshes that contain polygonal information, it’s very likely you will not get a 1:1 representation from DXF files.

I see, if that’s the case, is there a way around this to somehow get the 2D floor plan on Isaac Sim or is it really impossible to get my 2D .DXF floorplan into Isaac Sim. @Simplychenable @shalinj

if you need to interract with the floor plan, you will want to turn it into polygonal model. but if its for visual references only, then you can consider loading the floor plan into Isaac Sim as a texture where you can then apply it to a material and only a plane mesh.
