Measuring

The measuring tool answers the question every conversion runs into: how much room is actually there? Click a surface in the 3D view and it tells you the clear space out of it - to the far wall, to the ceiling, or to the rear doors - and names what stopped it at each end.

It is free on every plan, and it changes nothing about your design: a measurement is a question about it, not part of it. Nothing you measure is saved with the design or shows up in the bill of materials. While the tool is open, Undo and Redo step the list of measurements instead of your design, so a mis-aimed click costs one press.

What is in this section

Taking a measurement - the Measure menu, the four kinds, which way a span runs, and how the marker snaps.
The measurements list - reading what you have measured, clearing a row, and leaving the tool.

The van menu - shell visibility, which changes what you can see but never what a measurement stops on.
Units and sizes - measurements are written in millimetres or inches, which is the one place the app does not switch to metres and feet.
