Re: 3D staircase odd render
This is caused by the staircase floor cutout. By default the cutout is the same as the bounding box of staircase (i.e the width and depth of the object).

There are two ways to solve this.

The first one is difficult but it is the 'clean' way: export the staircase and import it in a library. In the library you can set a custom cutout that follows the threads. To do this you need to learn how SVG paths are created because a cutout is a SVG path. Here is a manual: https://www.sweethome3d.com/SVGPathMiniManualForSweetHome3D.pdf.

The second method is to export the staircase and import it as a normal object, i.e. NOT a staircase. That way it doesn't cut the square hole. Then you have to manually change the upper floor to create the hole for the staircase. This is relatively easy by adding/deleting/moving points of the room in the plan. With magnetism on room points snap to corners of the walls which makes is even easier.
