Joining or "connecting" closed curves

Good day,
I have scanned a set of templates for a radius wall cap and would like to join the five sections into one so that i may then divide the overall into equal pieces. I seem to be stuck with the fine connections between each template. Any advice would be great. Thank you

Hi Marcus -

To be able to join two curves, there need to be naked end points that are within tolerance from each other. You can’t join closed curves to other curves. Apart from that, there are gaps between the five sections:

I’d probably draw new curves based on the existing curves.
