OLP products use different program editor so add-ons won’t show up on it. You can replace the add-on’s init file with the attachment. Then the button will appear on the Program tab’s ribbon and then it works also on OLP.
init.py|attachment (767 Bytes)
If you are using OLP product then I suggest to get familiar with its inbuilt path generation tools for surface processes. In many ways I think those are better than this python add-on.
