DipTrace has panelizing function despite affordable PCB design software.
Lightweight program can run on low-performance PC.
Easy to understand the simple data structure thanks to functionally independent applications.
User can place dimension line directly in to the pattern.
Furthermore component pin and pattern pad are connected by line is easy to check.
These should be basic requirements for designers, but not implemented in other mid to high-end software.
DipTrace doesn't have tricky functional restrictions for lower edition, only the limitation of circuit scale.
Very nice.
