JKEdmo Posted October 30, 2023 Share Posted October 30, 2023 Had to do my first spiral stair today for an as-built and surprised that the stair tool could not handle it. I wound up using the library symbol. Just curious about X15's current ability to create spiral stairs? I read a number of old forum threads about the topic. If I understood correctly, spiral stairs still need fussy workarounds. Still true? Thanks, Jim Link to comment Share on other sites More sharing options...
KnotSquare Posted November 30, 2023 Share Posted November 30, 2023 Jim, Dealing with spiral stairs myself and looked it up just in case a new feature was added. Not that I know of, and it is a PITA as far as representation goes. It is not visible from floor to floor in plan view. I included the block I use in case it is better than what you have found. Good luck. Mark Large Spiral Stair.calibz Link to comment Share on other sites More sharing options...
KnotSquare Posted November 30, 2023 Share Posted November 30, 2023 Jim, @JKEdmo I am getting pretty darn close to a spiral using a straight stair, selecting the end and then bending it into a curved stair holding down the ALT key. One I got it curved, I am now in the process of getting the settings as close as possible to what I need and then will move it into position and see how it works. See if these settings give you a good head start. I will follow this topic, so let me know if you learn anything significant. Thanks, Mark Link to comment Share on other sites More sharing options...

Thanks Mark. Looks pretty cool. I'll try this tomorrow. Jim Link to comment Share on other sites More sharing options...
KnotSquare Posted November 30, 2023 Share Posted November 30, 2023 Here it is in position. A little fine tuning and I may have it. Mark Link to comment Share on other sites More sharing options...
KnotSquare Posted November 30, 2023 Share Posted November 30, 2023 RT Ray Trace: My home has 9' ceilings built using pre-cut studs, plus 3/4 T&G plywood, 1/4" foam pad and 3/4" engineered hardwood floors. The settings I landed on are: I then placed a post in the center, opened it up, changed it to round with a 3" radius and stretch it up to match the railing height. I set all materials to Black Brushed Metal. I am happy with the results. Good luck with yours tomorrow. Mark Link to comment Share on other sites More sharing options...
KnotSquare Posted November 30, 2023 Share Posted November 30, 2023 Oh, the floor framing is 12" deep floor trusses. Link to comment Share on other sites More sharing options...
DeLayDesign Posted December 1, 2023 Share Posted December 1, 2023 I build mine in two sections for each transition (floor one to floor two; and then two to floor three - 4 stair sections total). This allows me to control the riser and run without it going wonky. Granted this was a tactic I learned in X14 and it may be fixed in X15. Link to comment Share on other sites More sharing options...

I think I read in a previous post that a limitation of a single stair flight is that it cannot overlap or cross over itself in plan. Is this why you stacked 2 sections?

I believe I started a conversation a few months ago about it. Link to comment Share on other sites More sharing options...
