Split tool not selecting all the curves from a D sketch

[naqib_mashrur4YFQQ]

 I am trying to split this solid with this 2D sketch, but the split tool is not identifying the entire sketch as one tool. Why is that happening? And how can I select the sketches that have not been selected?

For additional context, this is an .iam file. I created the 2D sketch using the project geometry tool on the solids attached to this solid's face.

Hi!

 Why is that happening?

Probably the sketch is not all connected, probably there's a small gap somewhere.

Try this:

Instead of using the sketch as split boundary, extrude an surface using the sketch, and use that surface as the split boundary.
(If the sketch is not connected, you will see where is open (if it is open) when you're trying to create the surface).

If you share the model, i can take a look on that.

Thanks for responding. I think the sketches were not connected because there were multiple projected geometries from multiple solids. Where two solid faces met, an overlapping sketch was created. I made those overlapping sketches into construction sketches. That solved the issue.
