This instructable is to explain how to go from something you made a drawing off on Autodesk Inventor to CorelDRAW so you can laser cut it.  I found the first time I did this, it was not at all straight forward.  I still have not found a file format that will go straight from Inventor to CorelDRAW without an intermediate program.

Step 1: Start with a drawing in Inventor

Create a drawing in Autodesk Inventor.  Make the paper size the same size as the material you will be cutting from.  In this case, it is 24x4 inches.  Delete the border and title box Inventor puts on the drawing by default.

Step 2: What doesn't work loading into CorelDRAW

I have tried several variations of the .dwg file from Inventor.  Either Inventor or AutoCAD format produces the same results.  A corrupted or unidentified file type in CorelDRAW.  If you print a .pdf you get a corrupted file error importing that into CorelDRAW also.  The .DWF file format isn't recognized either.

Step 3: Next stop, Adobe Ilustrator.

If you print a .pdf file in AutoDesk Inventor that will load into Adobe Illustrator.  The .dwg files from Inventor won't load there either.  The .pdf file seems to be the only working thing that will load into anything.  From Adobe Illustrator, save the file as a .ai Adobe Illustrator Format file. 

Step 4: Finally, something that will work.

The .ai file you made will load into CorelDRAW.  Everything shows up.  Success.  It will load in with the paper size set to the correct size.

Step 5: Make everything hairline so it will cut.

The next step is to hit "edit" and "Properties" to get the right tool bar to show up on the right.  Next, select your entire drawing and you need to change the line width from whatever it comes in as to "hairline" thickness.  As taught in the Laser Cutter SBU class, the laser only cuts things set as Hairline.  Everything else gets raster printed.  If you want to have labels on your individual parts, you can go back and change the thickness of your letters to something other then hairline.  You can just wait until the file is in CorelDRAW and create your labels there in non-vector form.

Thanks for the hints. I will give that a try next time I laser cut something.

The same technique (Save Copy As .dxf) is used to import designs into VCarve for the ShopBot and Flowpath for the water jet.

Save yourself a ton of work. Create a 2D Inventor drawing of your 3D Inventor part. Select "Save Copy As", and select .DXF (drawing exchange format) and select AutoCAD 2000 as the version type. It will read directly into CorelDRAW as hairlines. DONE!
