circle on line with moving endpoints

[Frank-Bouwadvies]

Hello guys,

The purpose of this symbol is too put it in an random rectangle and take the grips of the lines to the corners.

The centerpoint of the circle must stay on the line

After that it must be possible that the circle can move left or right over the line.

The position of the circle is random but must be on the line.

With the grippoint it could be moved.

I made the circle with an polygon and an wipeout voor the text.

In symbol1 i used on one end the polar stretch action and it worked fine.

The grippoint stayed on the line and the circle also.

In symbol2 i made an extra polar action on the other end,.

But when i moved the grippoints to the corners, the lines and circle lost there connection.

In symbol3 i replaced the polar stretch with point parameter and stretch action.

The endpoint grippoints stayed on the line but the circle lost his position on the line.

And when i move on all symbols the grippoint of the circle the endpoints off the lines are moved with it.

Does anybody you know an solution??

regards

Is this a beginning to what you would like to achieve?

I replaced the point/move with a linear/move and it stays on the lines when moved.  It can be moved colinearly beyond the line endpoint, though, and I'm not sure how to eliminate that possibility.

Thanks,

This is what i mean.

I have update the symbol with other stuf.

Also i brought in an rotate parameter, because the text not stayed horizontal.

See my new drawing
