measure and dimensions

[brodbdie]

at the moment a roomsize is measured mid of a wall to mid of a wall.
it would be helpful to change in the settings the measure method to border to border. If setting up a plan the base is the etsimate and this is based on inside dimensions.

Hum, sorry if you find me a little rude, but this subject has been discussed so many times that I prefer to let you explore the forum to get a deeper explanation.
By the way, objects called "rooms" are drawn corners to corners, then you can double click in them with the wall creation tool to draw walls around them.
