How do I extend area skeletons/centre lines to the edge of the area?

I have a bunch of rectangles with differing orientations. I need to create a point between the two vertices on the short sides of each rectangle. That is, I need to create two points per rectangle. Something like this:





The problem is I have several hundred rectangles.

In the past, I have been manually creating each point estimating where the point should be by eye. Not ideal but it was sufficient for my needs.

Now I have a huge dataset and need to automate it if possible.

I tried the "create area skeleton/centre line" option. I figured I could then take the centre line and create points based on that (which should give me a point at either end of the line).

The problem is the centre line doesn't extend all the way to the edge of the area:



Of course, if I then create points based on that centre line, the points will end up within the rectangular area rather than on the edge of it:





Is there some way of automatically extending the skeleton/centre line to the edge of the area?



Thanks in advance,
Dave
