I have v19 that came with our 4axis foam hot wire machine.
I am trying to make a tapered shape with two similar profiles on each end. After importing a dxf with the two profiles and their restriction lines between them, the shapes are not closed which doesn’t allow the two chains to be selected during toolpathing.

I know this can be done because a previous employee made a tapered cylinder half.

Anyone know what I could be doing incorrectly.
Thanks in advance.
