Hello, I need help creating this specific balaced stair in chief architect premier x12. 

The only thing i could think of was to manually create every step from slabs. I still need to corect some steps from plan view but at least the height and length are good - now how can i add the rails on the inside and outside walls?


Or maybe is wrongfully thought from the start; what is the simplest, smartest way to create this type of stairs?

Should've done these stairs using shaped landings.

Since you've come this far with the manual method you could either draw your railing with the 3d molding tool or convert your slabs to plain polyline and back to landings. You will need to connect one stair section to be able to better control your stair railing, riser, tired etc. Information

BTW, the drawing does not seem to meet the IRC code of 10" min tread depth at walkline, 3/8" tread depth variation and 6" min tread depth on inside edge.


R311. Winder treads. Winder treads shall
have a tread depth of not less than 10 inches (254
mm) measured between the vertical planes of the

foremost projection of adjacent treads at the intersections
with the walkline. Winder treads shall have a
tread depth of not less than 6 inches (152 mm) at any
point within the clear width of the stair. Within any
flight of stairs, the largest winder tread depth at the
walkline shall not exceed the smallest winder tread
by more than 3/8 inch (9.5 mm). Consistently shaped
winders at the walkline shall be allowed within the
same flight of stairs as rectangular treads and shall
not be required to be within 3/8 inch (9.5 mm) of the
rectangular tread depth.

      I have a building which has a staircase outside of the structure that I'd like to display on the second floor plan. Is there a way to do this without creating walls under the stairs or encasing the area with invisible walls? Thanks!

      I have needed tom place stairs that go through a doorway on multiple occasions, and every time I try it would seem the program glitches and usually breaks the wall or the doorway so you can see the structural materials. The best solution I have found was placing two staircases on either side of the opening, but even that solution isn't perfect. Has anyone found a solution to this?? Am I doing something wrong? I feel like it's pretty common for stairs to go through openings, so it would seem odd to me if chief would not have an option for that.... I attached a picture of what I am encountering. I am using premier x13 beta, but this was also a problem in x12

      I'm new to chief architect and I'm having trouble with this tricky sloped wall. For some reason this weird cut out that reflects the shape of the stair railings is showing up on the ceiling. If anyone has recommendations on how to fix this please share! Thanks

      Hey All,
      My company is in the process of making the switch from Autodesk Revit to Chief Arch (Version X12) and I have been spending my time trying to create a lot of commonly used design elements we use on our plans but I have run into a hiccup. I'm trying to create a small, inset-type staircase (attached image is what I've done in Revit in the past) that is typically used on our plans to go from grade-level sidewalk to the main floor elevation. In my attempts, stairs either fail to recognize the elements around them or if I create them like I would in Revit in creates this garbled configuration where the stairs are their own room and the footprint of the stairs themselves cut a hole through the roof.
      Checking Forums, YouTube, and the Chief site have all yielded nothing and I in my limited knowledge cannot figure it out. What am I missing?

      A bit of an issue. I have two staircases. One from the basement to the first floor. Directly above are the other stairs which go from the first to the second floor. When I run "Auto Stairwell" on the basement stairs, the other stairs drop to the basement. I have never had this issue in any other versions. Why? (See attached screen shoot). Running CA12 on Win10Pro.
      Thanks in advance.
