.dxf import - Closed entity not creating a face to extrude

Eric_92Eric_92 OS Professional Posts: 22 PRO
First time trying to use an import.
I get it into the file just fine but the shape is not a closed pline, it's made up of splines, arcs etc. however all the endpoints are snapped together.
When imported it comes in just fine but does not create an enclosed body to extrude - I can only make a cookie cutter out of the edges. See screenshot.
I'm sure there is a way to fix this either on the 2d file or in onshape. Any ideas?
I'm pretty sure the issue is the Splines and it not being a closed polyline but don't know how to fix that.
(in the screenshot there are 2 copies of the sketch as I was messing around)

    Note - Just tried replacing the splines with arc's and making the whole shape a closed Pline - same results in Onshape.

    @Eric_92 could you share your document so we can take  look, DXF imports are tricky sometimes.

    Thanks Andrew.
    I got it to work by individually going through each point and re-snapping them to the adjacent end point, then it created a solid.

    The other work around was simply "useing" the imported sketch as tracing paper and drew / mirrored new geometry over it using the same endpoints. crude but also worked for this simple geo.

    Hi, all!

    I'm having a very similar sounding issue when importing a DXF into sketchs. I tried going through the whole sketch and making points/lines coincident throughout, but after reviewing it for a long while and still not getting a closed surface I'm hoping one of you might be able to help:
