By adding stairs to the house, the addon runs the measurements of all other objects, walls, doors, ceilings, windows, etc. The same effect is reproduced by adding a light bulb.
I don't know how to use the addon.
Can you give me exact steps to reproduce the "error", please?
Also it would be helpful if you describe what the error is in more detail.
Well, first you have to create at least 3 rooms, put in windows and doors. Then place the cursor inside one of the rooms on the edge of the floor. In object mode you must go to add, mesh, archmesh and click on add stairs.
When that happens the stairs are added with 3 steps, but it misconfigures the measurements of the other objects created previously. Also, the configuration options of the stairs do not appear in the sidebar panel (N).
I have noticed that the creator of the addon is Spanish. Do you want me to put the message in Spanish so that he can understand it?
I cannot reproduce it on Windows.
About stairs panel missing, this is a feature not supported (the stairs can only changes at creation, but not later)
