How to import AutoCAD file into Design Modeler?
How can I import a geometry created in AutoCAD into Design Modeler? Can anybody help me with that? Thanks!

Import Geometry and Browse to the folder where your file is...
If you don't see your files, check the filter. This may be licensing dependent. There is a special key needed to import Autodesk formats, just as there is one to import Pro/E or NX formats. I think this is less nitpicky with the Academic keys. Attachment 4026 Coming at 13.0, we have added some new import formats (such as JTOpen and STL), removed some of the requirements to have CAD software installed, etc. |
If you are using the academic version, most packages of this come with the geometry interfaces and you can import as above.
If its a commercial license, you will need the autocad geometry interface license or simply export you geometry to step format and open it in design modeller. |
Hi,
I am trying to import a 2D drawing form AutoCAD 2008 into the DesignModeler. the import option is available, although when I generate the model, there is an error. --------------------------- ANSYS DesignModeler 12.1 Error --------------------------- Error: Attach failed Context: Attach Feature Import1 --------------------------- OK --------------------------- can anybody help me on that? thanks. |
3D dwg only...
Sorry, I just checked with development and they told me that currently, the autodesk reader is only for 3D dwg files. However, they are enhancing it right now so that the next release will support 2D.
|
I have a very simple AutoCAD version 12 3D dwg file that I am attempting to import but get the same 'attach failed' error message as Arash.
Is there something else to know? |
Hi Rae,
Apparently importing the CAD drawings does not work properly. Simon told me that it will be fixed soon. Try ICEM to mesh you geometry. ICEM is fairly straight forward too. |
Hi Arash, Meshing is my next step so thanks for the advice.
On my 'Geometry' - I noted 'Inventor Fusion' seemed the preferred source in ANSYS discussions so I opened and saved my '.dwg' file in '.igs' format using Fusion - ANSYS workbench opened the '.igs' format without a hitch. |
importing from Autocad to Ansys
hello
to import autocad 3D objects to Ansys. Export them from Autogad in IGES format using the subscription package of licenced version of Autocad . Then import it in Ansys geometry. this works for me |
I thought the problem was just with 2D AutoCAD. No one was complaining about 3D models... (yet?)

Hi
I'm trying to import a 3D geometry to Design Modeler in STL stp ir iges. none of them works for me and i get the "attach failed" or "no body found' error message. Anybody got any idea? Cheers, |
RE: 'I'm trying to import a 3D geometry to Design Modeler in ... iges.'
Hi, My experience with DM is that it imports geometry in '.igs' format without trouble. There may be some structures which can't be imported (haven't of course tried them all) and there may be some structures ignored (eg. from memory there are configurable DM settings to ignore certain information like names or material properties). I suggest you try again, maybe starting with a very simple test geometry. |
Faceted Geometry...
STL should fail because DM does not yet support faceted geometry.
IGES or Step should work, if they are bspline or nurb geometry, but if you are starting with some faceted format and just output faceted geometry as Step or IGES, then it won't work. So, what was the source? |
Hi
It is actually a packing of particles ,3d geometry. As you're saying it seems that it can not be imported to Design modeler, it is not just a bSPline. |
Can I instead import the coordinateds and the radius of my spheres in the packing, so Design Modeler can generate the geometry automatically? What's the procedure?
|
Example...

Yes, you could write a script that would take in those coordinates and radii and generate the model...
Here is an example to get you started... See the attached zip file...
This example should give you some idea, you can figure it out from there (or call Tech support for more info, I think this script was made by Vamsi Krishna at ANSYS). And don't forget to have fun with it. |
PSYMN,
I think I have a similar issue - my aim is to use Matlab to generate 3d coordinates of a rotor (done), export the coordinates into excel (done in Cartesian and in Cylindrical polar) and then get them into ANSYS. I am only using DM 12.0.1 - is that the problem? When I run the script you so kindly uploaded, I receive the following error in a pop up box: Script Error Line:11 Char:0 Error:Automation server can't create object Code:800a01ad Source: Microsoft JScript runtime error Script: var dlg = AnsObject............. Anything you can say to shed light? Many thanks, Ed |
I get the same error eheywoodlonsdale does. I'm trying to do the coordinates of an airfoil.

Hello All,
I am trying to import the 2D Autocad geometry to design modeler, but can't do it. But I can import 3D geometry. I am using Ansys 14.0. Is it still unable to import 2D as this post says? Please someone who knows about it clarify my query . Thanks in advance. Tanjina |
I am not sure about 14.0. We have had two releases since then and will very soon release a 3rd.
At the moment (14.5.7), it is more entity type limited than 2D vs. 3D. Here is a listing of things that were tested for: Quote:
