Does 16.5 support test point generation?
Layout had the ability to convert vias to test points and to also add test points. I do not see anything like this in 16.5.
I believe that last Layout version I had with the autorouter was 9.2. I probably bought it back in the late 90's. Since I never really had the need to autoroute, I dropped down to the packages without it.
The basic Layout program could generate testpoints automatically. PCB Editor needs to be the "professional" version to do it. (another 3K).
