Do you want to know what the distance between the pads is, or do you want a dimension to show the distance between them? Distance between them, use DisplayMeasure, click on the pads in turn, the 'Air Gap' will be the Pad Metal to Pad Metal distance. For the dimension, which version are you using? (The 'Snap pick to' differs between versions). Hi all, I'm pretty new to using Allegro for PCB design, and I was wondering what units are quoted by the 'show measure' command. The numbers in the pop-up window display no units, but I'm curious as to how to figure out the length (preferably in mils) of traces on my PCB.
Mentor PADs features a variety of “modeless” commands that all you to change settings on the fly using quick keystrokes instead of poking around through the GUI menus. This post describes some of the available commands using the Layout package. To activate the commands you simply start typing when the software has focus. After the first keystroke a dialog will appear showing the command.
