Pirform lets you quickly and easily create one certificate from another. Old Periodic Inspections can be turned into new Condition Reports or Installation Certificates, create Minor Works from Condition Reports, and so on. This is a really powerful feature that can save a lot of time and effort.
First, just select the certificate you want to create another from in the Home Screen, then click the Create Certificate button in the ribbon.
This will give you the option of creating a copy of the certificate, or creating a new Condition Report, Installation Certificate or Minor Works from that certificate. As you'd expect, all the relevant details are carried across to the new certificate. If you're creating a new Minor Works, then you get to select which circuit to use in the source certificate:
Lastly, the Create Certificate menu also lets you merge boards and observations from different certificates together. You can read more about that here.
