Exporting solid from AutoCad 2016 to Inventor 2019

[pierrot.dufour]

Hi everyone,

Can someone please help me on this. I'm trying to figured out how to export 3D Cad Solid to Inventor. I tried .iges/.dxf/.sat and its always get messy (look at the screenshot). I'm not familiar with Inventor, but I just use Manage, Import. 

Also, my main goal is to export 3D polymesh face from AutoCad to Inventor. When I import them in Iventor, faces are not merged together and multiple triangulation appears.

Mesh is not solid.

Inventor will open AutoCAD dwg directly (solid or mesh) - no need to Export in AutoCAD.

4 Options.

1. Create high quality solid geometry in AutoCAD to be opened in Inventor.

2. Repair poor quality geometry in AutoCAD before opening in Inventor.

3. Repair poor quality AutoCAD geometry in Inventor after opening.

4. Use the poor quality AutoCAD geometry only as reference in creating high quality solid geometry in Inventor.

Hi! Besides what JD mentioned, you can also use command ACISOUT to write out SAT file. Inventor can import it too. Based on the image you share, another possibility is that the solid bodies are extremely far away from origin. Could you do DIST in AutoCAD to measure the distance between the solid and the origin? If it exceeds +-100m in X, Y, and Z direction, the geometry is located outside of Inventor valid model range. You need to move it closer to origin.

Could you tell me what you are trying to do in Inventor with these solid bodies?

Many thanks!

Thanks JD for answer!

Since our client want to work in Inventor, I'm trying to make it work in Inventor.

In AutoCad, I have one surface for one wall, but in Inventor, I get multiple triangle for one wall. Do you have an idea how to merge together the triangle in Inventor? You will find attached the .dwg file and the resulting .ipt file. There are a huge diffrence on quality. The main goal is to have one surface for each wall. 

Thanks a lot for help!

Who is creating the AutoCAD geometry? You?

Is the person creating the AutoCAD geometry using vanilla AutoCAD, or are they using an add-in to create the geometry?

There is no reason that perfect geometry cannot be created in vanilla AutoCAD, but whoever created this geometry used a combination of 3D solids and Mesh.  They made some errors in creating the 3D solids in some locations (90°bends), but for some reason created torus solid in other "identical" situations.  There is a simple solution for these bends.

I would say this could all be resolved with a bit of training.
