How to add SMT test points ?

SOT23

Hello ! 

I am trying to add SMT test points to a board but couldn't find a way to do that. I tried : 

  • creating a single SMT pin footprint that I manually added, but I can't easily set a net to it to make it a test point.
  • creating a SMT via (just a 0.6mm circle on bottom layer), but I cannot add them to the board. I can add them to the Via list in the Physical Constraints Manager, but when I try to add them by using the Cline command (like I would do to add a THT via), it doesn't work, the SMT via doesn't appear in the list...

How could I simply add an SMT via to the board ?

Thank you !

    While in the 'add connect' command, in the Options tab, set both layers to 'Bottom', then the only via that should be available is the SMT via

    It works for me...

    Still on the topic of Test Vias : 

    Does anyone know if it is possible to add a Placebound to a Test Vias ?

    I tried adding a layer in the padstack definition, but I cannot add constraint to it. Is it possible to define that layer so that it acts like a placebound ?

    For what purpose?

    To have a place boundady the test point have to be a component from schematic/netlist.

    If goal is only not to have tres point under compoennt, just set testpoint parameters correctly (do not allow under components)
