The "Import" ribbon hosts four of the most basic menu options, if you want to start a new job. While the first three, Favorites, Recent and Browse, are strongly linked to each other. It gets evident by opening one of those menu items because it is the same dialog. Import is rather independent, which can be seen by the ever changing dialog depending on the corresponding file type you want to import.
The favorite menu is a typical favorite option that provides links to designs, which are frequently needed. For a better searchability these links can be renamed and given an individual icon. The radio button selection at the bottom of the dialog indicates, where changes to the design made with PCB-Investigator are saved. There are two options:
Recent is a typical history list, it lists links to all recently opened designs and allows them to be added to favorites by right-clicking and selecting the corresponding function.
Browsing lets you import files, but also add important or frequently needed folders to either QuickLinks or an individually defined Server Tab by right-clicking on the concerning folder and selecting the desired option.
Every time a job is opened, a thumbnail is generated and saved locally. The thumbnail is updated every time the job is opened.
You can import data from 365 storage directly in the import area.
