Cut Vector Drawing into Ring

[pcroden]

I'd like to cut this Celtic knot pattern (Sketch 20) into the loop of this ring, so that it cuts all the way through. Eventually I'd like it to be symmetrical on both sides. I can't seem to select the profile using the Emboss or Extrude features. 

I used Aspire to create the vectors, by converting a raster, and imported those vectors through a DXF file. Short of hand-drawing each of these curly shapes, is there a way I can use what I have to make this cut?

Alternatively, I was able to project the shapes onto the ring as you can see in 3D Sketch 2. Is there a way to use that 3D sketch to cut out the shapes?

Final question - it's just a bit too long on the Z axis. Is there a simple way to compress the entire graphic along one dimension, or would that need to come at an earlier stage?

Looks like there are multiple open loops in your sketch.  Those will all need to be closed up before you will be able to use the sketch for any feature creation.

Best thing to do is to fix your DXF. First try using overkill and purge on your DXF before bringing it in. 

You'd be better off redrawing it though so your jagged edges are actual arcs. It seems to be a continuous pattern though so might not take too long. 

If you don't want to fix your data, you can try boundary patch:

Then thicken cut the patch. 

It will take ages and probably crash/error before you finish.

Wow, yeah that's a lot - How did you pull up this list of errors?
