Fusion 360 Not Exporting iges

[Anonymous]

Hello,

I am doing a project for a client that is requiring me to use that format IGES. This is the only program that I know can do that. I imported the model and just export it out as an IGES. When I try to open the exported IGES file nothing is there. Do you know what my issue is?

Hello,

Are you able to share the fusion file with me so that I can take a look at what may be going on?  As a follow up question, what are you using to open up the exported IGES?

Here is a quick link that shows a couple different ways to share the fusion file.  https://knowledge.autodesk.com/support/a360/troubleshooting/caas/sfdcarticles/sfdcarticles/How-to-sh...

Cheers,

What's in the model you're trying to export. If you've imported a mesh file Fusion will not export the mesh to an igs file.

Hi @Anonymous

Thanks for posting! The only way I was able to get Fusion 360 to export an empty IGES file was when I tried to export a sculpted t-spline body before using the Finish Form command, which converts it to a b-rep body. When you open the customers file, do you see the Finish Form prompt shown below:
If so, finishing the form and then exporting the file should create an IGES model. If this does not work, would you mind sharing the Fusion design that has failed to export with me? If you cannot share the design publicly free free to send me a public link in a private message - I am happy to have a look!

I can't give you the file i am working because of confidentiality. However, I am having the same issue with another file that I can give you. All I am doing is bringing in the file and exporting it out to IGES. The people that I work for said that the IGES file is empty. I tried reopening it in Fusion and the data isn't there. I have the error message of it too.

Ok So I am importing a mesh into the program. From what I understand that is my issue. Is there any way to convert it? I also have a dwg. file that is doing the same thing

Hi @Anonymous

Thanks for sharing the example file! It looks like mesh bodies will also not export in the IGES format - converting the mesh body to a b-rep body allowed me to create an IGES file. The command for this is accessed by right-clicking the mesh body in the browser:
Is your DWG file a 2D drawing? I had no issues with exporting 3D DXF files opened in Fusion as IGES files - can you share that design?

IGES format specification does not support meshes. Converting to B-Rep is a good idea before exporting to IGES. 

Or if you want to keep the mesh definition, use STL or OBJ as the export format.

As I mentioned before I can't share this the file info with anyone. I am importing a DWG file and i need to export it out as IGS. I figured out the model issue.

I read on a different form that I can't take a dwg. file and export it out to an IGS or STEP because those files only read solid objects. Can someone confirm with me on this. 

[smadhanraj]

IGES and STEP formats support curves, surfaces, sheets and solids. If the DWG file has any of these entities, you should be able to export from Fusion (or AutoCAD) to IGES or STEP successfully.

Hi @Anonymous

Thanks for the response! You can have either 2D or 3D DWG files - it could be that yours contains no 3D geometry as solid objects, which would prevent you from exporting it in IGES format. You can, however, save a 3D DWG file of designs that do include solid bodies from your A360 Dashboard in a web browser:

I tried to export out of AutoCAD and it didn't give me the option for IGS or STEP. I am using fusion as a work around because I read that fusion supports these exporting files with AutoCAD doesn't. When I export my dwg drawing out to IGS, It just comes up with the warning that nothing is in the file and it is empty. So frustrating! Thanks everyone for the help so far

[smadhanraj]

IGES supports 2D drawings and AutoCAD can export 2D drawings to IGES. Exporting from AutoCAD is the best way if you have a 2D DWG. 

File->Export has the IGES export option. or try igesout or igesexport command.

Fusion does not support exporting 2D drawings to IGES.

I have already tried that before I went over to fusion. The commands didn't pop up anything for IGS. I am using AutoCad 2014 on Mac if it is something with that version

[smadhanraj]

I confirmed that AutoCAD 2016 supports IGES export.

Just in case, if you have not seen this:

here is another forum thread that talks about exporting from AutoCAD 2014.

I see that. I went on my brothers computer that has it. Mac doesn't carry that Version so we will see if it works or not. crossing my fingers.

To summarize,

IGES supports 2D drawings, curves, surfaces and solids.

If your original data is mesh geometry, exporting to IGES does not make sense. It will always fails as IGES file format does not support meshes. In this case, open dwg in Fusion, convert to B-Rep first and then exporting to IGES will work.

If your data has 2D drawings, use AutoCAD to export to IGES (Fusion does not support exporting 2D drawings).

If your DWG has 3D B-Rep data, any of the products (AutoCAD, Fusion, Inventor) will successfully export to IGES.

Good luck.

Hi,

Right now I have a file in Fusion cloud which is having 10000 triangular faces. To convert to IGEs format what are the step to be followed. I converted to .DWG but failed to convert to IGES or STEP. Can any one help in this matter.

Your question should be posted over here 

https://forums.autodesk.com/t5/fusion-360-design-validate/bd-p/124

as a new topic and linked backed to this one (if this one was relevant).

Attach your *.stl file here and I will see if I can convert it to a solid body.
