I'd like to be able to connect two shapes in different ways than center to center.

For example: connect two squares at specific corners rather than center-to-center.

However, if I move the connection point, the connection gets lost and when I move any of the connected shapes, the connector doesn't move along with it.

I have found that there is a connector-start-point in the source code (see here) but I can't tell what it does.

Any help?

Thanks!

Not sure if there is a legit way to relocate the anchor point, but in the meantime maybe this workaround...

Connect to some small objects and group to the target object:

Thanks. That works if you build the doc by hand. Since I was looking to manipulate it directly via python/SVG etc, maybe in an extension, I was wondering if that property actually did something.

I tried messing around in the SVG file but the question is "what do I set it to"?

I'd ask the developers on the Chat (separate login): https://chat.inkscape.org/channel/inkscape_user
