You can easily change the units of measurement in Altium Designer's PCB layout (or schematic) using a simple command or keyboard shortcut.
Methods to Change Units in Altium
There are a few convenient ways to toggle between different units (commonly inches and millimeters) within your Altium Designer PCB layout environment.
Here are the primary methods:
1. Using the View Menu Command
One straightforward method is to access the command directly from the main menu.
- Navigate to the View pulldown menu.
- Select the "Toggle Units" command.
This action will switch the display and input units to the alternative measurement system (e.g., from Mils/Inches to Millimeters, or vice versa).
2. Using a Keyboard Shortcut
For quicker access, Altium Designer provides a keyboard shortcut:
- Press the "V" key on your keyboard.
- Immediately followed by pressing the "U" key.
This "V", "U" key sequence performs the same function as the "Toggle Units" command in the View menu, quickly switching your units.
Reference Information: As stated in the provided reference, you can use the command: “Toggle Units” found in the View pulldown menu. Additionally, you can use the keystroke shortcut combination of "V" followed by "U" on the keyboard to change the units.
These methods allow you to quickly switch between Imperial (Mils/Inches) and Metric (Millimeters) units while working on your PCB layout or schematic in Altium Designer.
