Bill,
Altium offers the same option. Once you define the test point grid it
will change vias on that grid to test points. At least it did in DXP and
99SE, I haven't had an opportunity to try the new Altium Designer. I am
currently learning P-CAD 2000 and I place all my test points as components,
it is very time consuming. I have been trying to talk my new employer into
upgrading to the new Altium Designer.
Regards,
Ted
