3D model request: Pie shaped primitives
I have looked all over the web for a 3D model that I can use to make a stairway. What I need is a truncated pie-shaped wedge which will be used as a single step in a circular stairway. I do a lot of stairwells inside round towers and I need to form the stairs depending on different radiuses.
If anyone it's up to the task I'm requesting a 3D model that I can import into sh3d that looks like a portion of a disk, but instead it's a pie-shaped section. Imagine a disk with a hole in the middle but instead of going 360 degrees around, the arc only goes around 6 degrees. I actually need models that use a 5-degree arc, 6 degrees, and 11-1/4 degrees. With these I can make just about any stairwell I need. To account for the inner wall, the radius should begin at a quarter, 1/3, and halfway out towards the outer circumference.
Can anyone provide these 9 models that can be imported into the program? Any floor plans I publish or share will give credit.

Re: 3D model request: Pie shaped primitives
You should be able to create any shape of this type using walls and floors. Go to preferences set wall height and thickness to something like 3mm (1/8), draw a rectangle of walls approx the size of the tread needed. then modify each wall, length angle and arc to achieve the size and shape you need. Select the room tool and double click within your walls. Add another level to your plan, you can set its depth to match your tread. Copy/paste the room from the ground level to your added level. select the room and go to modify, uncheck the boxes for area and ceiling. Finally export it and import it

Another way to do it, if you don't want to make the shape in sketchup, is by using the triangular box. Make the steps over sized, going through the walls to fill the space. And where there's an empty space left just fill that with another smaller triangle, oriented accordingly. It is the most straightforward way, short of making the exact shape that you need.
P.S.There's a little glitch though, some holes will appear in the ground surface projected from the smaller triangular boxes inside the wall. Easy to patch with, you guessed it -another triangular box-. It's triangular boxes all the way down.
