I can't believe it's been so difficult to take 1 simple shape and get in into something 3D for printing. If I import a DXF in FreeCAD, it makes my object a big blob that only roughly has the same shape as the original shape. When it opens in FreeCAD, it's not even close to being symmetrical. I drew an object in Illustrator, mirrored it and welded to together. Downloaded FreeCAD and when it imports the file, it messes up the geometry. It created all kinds of crazy lines running all over the place, making my drawing look like a porcupine. I went back into Illustrator, exported as a DXF and then imported the DXF in Blender and it was a real mess. Can't get my SVG file into Blender either. It appears only the online version allows any importing and when I export an SVG file out of Illustrator, it comes into 123D as just one solid block with no geometry. I'm very comfortable creating drawings in those programs, but I've spent no less than 20 hours in the last 3 days trying to get things into something that is 3D and I'm at my wits end and need some guidance. Have a background in vector graphic programs (CorelDraw, Illustrator).

Greetings all! Thanks for allowing me to post my first post.
