How to constrain a family to a reference line that moves and rotates?

Prvoime — Mon, 31 Jan 2022 14:40:57 GMT

I place a family on a reference line, when the reference line moves, rotation part work OK, but when I try to constrain it to the end of the reference line so that it stays at the end of the line, I get "constraints not satisfied".

Any idea what I'm doing wrong because I'm semi-certain I did this already in some other family and it worked (no idea how).

Here's a gif.

Do you mind upload the family?

One way to do it is adding a perpendicular ref line and lock it to the end of the original ref line, then lock the end of the family to this line.

See attached.

Works, thank you very much!

How do people come up with these solutions?
