ZofzPCB simplifies comparing two PCB revisions, enabling you to make informed decisions about your design changes. By loading two revisions into the viewer, you can visually analyze the differences between them with ease. Here's how it works:
In the compare mode, ZofzPCB renders both PCBs to separate frame buffers and then calculates their pixel-level differences. The result is presented on your screen, clearly representing the changes between the two revisions. (See the picture above.)
While ZofzPCB primarily focuses on simplifying the process of PCB revision comparison, it also lays the groundwork for future project assembly involving multiple PCBs. It's important to note that, in the current version, there isn't an automated position adjustment mechanism. Therefore, users must ensure that the loaded PCBs have precisely the same offset to achieve accurate revision comparisons.
To manage multiple document instances effectively, we've included a list window displaying thumbnail images of all loaded boards. You can easily close any of the boards through this dialog. Using the <TAB> key, you can switch between three visibility modes:
When you check the "Compare Mode" checkbox, the first mode will display the difference rendering, while the other two modes allow you to view each board separately, facilitating detailed examination.
To ensure a successful comparison, please keep these important notes in mind:
