I am a retired electrical engineer and have spent a few days learning LibreCAD.

My goal is to design an object for my 3D printer by creating a 2D form
and extruding it for 3D printing.

I have a rather complex (hexagonal like) form composed of many
arcs and lines but find I can't "hatch" it because LibreCAD says
it isn't a "closed contour".

I understand that this means that (somewhere?) the end of one of
the 'arcs' doesn't match the end of its adjacent line.

In examining the entities (modify) the line has an ending X,Y value
but the arc has an ending ANGLE !

How can I identify the locations where there is a 'gap' (I can't see any)
and how can I match up the ends of arcs and lines?

I haven't been able to find the relevant tool for checking/fixing
"closed contours" - is there one or is that still on the "to do" list?
