Yep got it and it works great. Made one change so the menu item comes up as import 2D DXF so I can have both loaded at once.

Looks like the spline were only used in the lettering and the isso view of the part and for some reason the set screw hole (no idea why that one is). The flat parts all imported with no issues other than the dotted hidden lines came in solid which is a non issue for what I am going to use it for.

after a little pushing and pulling (and manually adding the set screw hole back)

Thanks again for the help!

Yep that looks like the part (cog belt pulley (only 2 teeth are shown)

Segmented lines are fine by me. I can go in and touch them up manually while I am turning the 2d drawing back into a 3d part.

I think the z axis is undefined since this is a 2d print. You can lay it out at z=0 (or any value for that mater) The print is going to get cut down to just that center part (big circle) then pushed / pulled back into the 3d part. So will be moved around quite a bit.

Thanks much for taking a look at this!!

Version 1.18 and not sure why I cannot attach anything.

Here is a link to the cad download page for the part I am trying to import.

i chose the "DXF file (.dxf)" option.
I also verified I can open the file in a dxf viewer so 99% sure the copy I have is good.

Thanks again for taking a look. It's a simple part so can draw from scratch if I need to. But use quite a few parts from them so would be nice if I could get them to import so I have a base to draw from.

First off thanks for the import utility!

Been trying to import a dxf from stock drive products of a timing pulley. Unfortunately only 1 line in the drawing makes it. Did not get any errors or unsupported entities so not exactly sure what happened...

Can you take a look at it?
