Type where you draw
With Dynamic Input, the command, the prompt and the exact length or angle all appear next to your cursor. You type the number there and keep your eyes on the drawing. It is on from the first start. How Dynamic Input works
Musa CAD Wiki
Musa CAD is a free program for 2D technical drawings: parts, plans, sections and sheets. If you have used AutoCAD, you already know how to use it. The commands, prompts, ribbon and keyboard shortcuts are the same. This wiki shows you how to install it, how to draw with it, and what every command does.

How to read this wiki
Section titled “How to read this wiki”Every page tells you how far to trust it, just under its title:
- Complete means the page covers its topic.
- Partial means it covers part of it, and says what is missing.
- Not written yet means the page only shows what Musa CAD itself reports, such as a command’s name, shortcut and first prompt.
- Checked against Musa CAD 0.8.0 is the release the page was last tested with. If a newer release comes out and the page has not been checked again, a note at the top says so.
The command lists and the pictures of drawings are made by Musa CAD itself whenever the wiki is built, so they always match the release it was built for.
Nothing here is copied from Autodesk’s documentation. Every page is written from Musa CAD’s own source code, its own prompts and real use.
