Building a Wall in FreeCAD Without the Manual

TL;DR

• Close every tab but the start tab, then open the BIM architecture project and set top view with the view gizmo.
• Enable Selection View under View -> Panels so you can see what’s actually selected.
• The Rectangle tool doesn’t confirm point selection, which makes it confusing until you trust it.
• Use the 3D offset with the mouse inside the square to set wall thickness; the 2D offset is the default and isn’t what you want.
• Upgrade and Downgrade finish the perimeter, despite names that suggest nothing useful.

Working out how to build a wall in FreeCAD’s BIM architecture setup. Writing the steps down because the interface gave me no help and I’ll need this again.

1. Clean the workspace. Close every tab except the start tab, open the BIM architecture project, and set the top view with the view gizmo.

2. Enable Selection View through View -> Panels. This is the single most useful thing I did. FreeCAD gives poor feedback about what’s currently selected, and Selection View makes it explicit — worth turning on before anything else rather than after getting confused.

3. Draw the rectangle. The Rectangle tool needs a first and second point, and it doesn’t clearly confirm that it registered either. That ambiguity is where I lost the most time. Once you know it’s silent by design, you can carry on.

4. Offset in 3D, not 2D. Place the mouse inside the square and apply a 3D offset to work inward, which is what defines the wall’s thickness. The default 2D offset doesn’t do this. This is the step that turns an outline into a wall.

5. Upgrade and Downgrade for the perimeter. The names are unhelpful and don’t map onto what the operations do, but downgrading under the right conditions produces the result. Trial and error rather than understanding, honestly.

The recurring theme is terminology and feedback that don’t help a newcomer. Nothing here was conceptually hard; it was hard to find. Which is exactly why it’s worth writing down.
