I have a simple 2D geometry designed in AutoCAD and I would like to import it into Design Modeler. However I receive the following error message when I try to import DWG and DXW files:


I would appreciate it if I could get some advice on how to resolve this issue.

It's possible that you've not installed the CAD readers but equally dxf/dwg files can cause problems due to the format. Can you export STEP and try that?

Thank you kkanade for your response. I tried IGES format but I got the same error. I tried all the other available formats that I could export my drawing (image below) and none of them worked. For some reason I do not see the step or parasolid format. Do you think there is is till some issue with my version of ANSYS? Or is there another way to resolve the issue?

Hello rwoolhou


Thank you for your response. For some reason I am not able to export STEP, maybe my AutoCAD is limited. As I mentioned to kkanade, I tried all the available export formats (image below) and none of them opened in ANSYS, I got the same error message. Do you know of any alternate solution?

please convert your drawing in autocad into a surface or solid body. then try.

Also, click on the DesignModeler box and set properties to mixed lines & surfaces (or similar): I've had another user have problems with AutoCAD & SolidEdge and think there's something odd with the export.  Creating faces or solids ought to resolve this too.

Hello rwoolhou and kkanade


Thanks to your useful advice, my issue is resolved! I first exported the IGES files using AutoCAD Mechanical and then set the properties of DesignModeler to mixed lines and surfaces. I did not need to try to create a surface or solid on AutoCAD.
