I'm trying to import a simple IGES file into vanilla Autocad. I found the IGESIMPORT command and I can get the geometry to import. The issue I am having is that the geometry is importing as splines. Even if the geometry is a straight line, it is imported as a spline. Perfect arcs also import as splines and I can't find a way to convert them.
In Autocad Mechanical, I can use the IGESIN command and the geometry imports as regular lines and arcs. I'm working with a customer that doesn't have access to Autocad Mechanical and trying to find a solution for them with vanilla Autocad.
A very simple example is attached in the .zip file.
I tried your IGES-file and yes, I can reproduce the SPLINE-generation.
What I tried then:
....and that creates lines, but rotated away from planar to WCS where the splines where placed. Could it be that your geometry was created in any angle or mirrored or none-planar to world before they where exported?
Sorry, that's not more then a few thoughts to think off.

No, this file wasn't created in a skewed view. I created it by using the line and fillet commands in Autocad Mechanical. I then used the IGESOUT command to create the IGES file. Then I tried to import into Autocad using the IGESIMPORT command and got the splines.
For Patch, what do you mean by FLATTEN? Is that a command I should be able to type? I typed FLATTEN and I get "Unkown Command".
>> what do you mean by FLATTEN?
It's a command within the ExpressTools (which are part of AutoCAD, but has to be separately checked for being installed).

OK, one last question. I primarily use Inventor, so I'm not as knowledgeable on Autocad these days.
I installed Product Design Suite Ultimate and I didn't configure Autocad to install the Express Tools. Can I go back and now install the Express Tools?
OK, we are making progress. I was able to go back to the install for Autocad Mechanical and add the Express Tools.
Now, how do I use them? Do I have to activate them or something? I typed in Flatten and it still comes back as an unkown command.
It's not your fault at all, it happens for many Mechanical users.
When you went back and add the Express Tools in the Control Panel, it installs Express Tools wherever it wants.
1 In Options, showing where the program is searching for Express and nothing in the Menubar.
2 Use windows search to get the true location where it's installed
3 Repath it.
4 It's now ready to go to work.
