Joe_Carrick Posted February 20 Share Posted February 20 Hi Ron, Spiral Stairs have very specific requirements which the current Stair Tool can't address: Max Riser height = 9.5" Min Tread depth at walk line = 6.5" Min Tread width 26" inside Handrail Generally the above will mean a minimum Tread angle of 30 degrees. The number of treads will be determined by the floor-floor height which means the total included angle may be more than 360 degrees. To get all of this Chief would need to have a completely separate tool for Spiral Stairs which would need to specify the above plus: Inside Radius (pole diameter/radius) Outside Radius Bottom Elevation Top Elevation It's not realistic for Chief to just provide a stair symbol since there are too many variations. Several years ago I created a set of 3D symbols (components) to make up any required Spiral Stair. These included: Treads (with and without risers) Poles Handrails (a variety of styles) Landings If you have a specific situation you need I can make the symbol for you - $100 each symbol. 1 Link to comment Share on other sites More sharing options...

It would a great service to users if they did spend the time and energy to give us a useful spiral stair tool. Just my opinion!!!! Link to comment Share on other sites More sharing options...
