PHIN Posted January 21, 2008 Posted January 21, 2008 How do i make a spiral stair stringer in 3d? can you please me? what commands do i use? Quote
mehiar Posted January 22, 2008 Posted January 22, 2008 well... i saw one a tutorial talk's about how to make a 3d spiral stair .. it was good ... First. made a Circle with a radias u want for the stair ,,, Sec. use Divide or div .. command to divide the circle equaly and the divide number depends on the stairs numbers u need ... 3rd. After that use ray command from the center of the circle ... 4th. use trim to cut the unneeded lines from ray.. then take a slice from the circle .. 5th. Close the slice by pedit or region or bo commands ... and extrude it ... and this will be the main shape .. 6th. copy the shape and past it ... and use align command to stick the stairs together... keep doing this till u have a spiral stair i will try to put some pics to help to understand it ... thnx ...

SEANT Posted January 29, 2008 Posted January 29, 2008 Here is a spiral stair stringer done with pre-2007 AutoCAD techniques. See also following post. spiralStairs.dwg Quote
SEANT Posted January 29, 2008 Posted January 29, 2008 These were the individual segments prior to UNION. spiralStairsOrig.dwg Quote
SLW210 Posted January 29, 2008 Posted January 29, 2008 The link I gave has a pretty good example of how to do it. Quote
PHIN Posted January 29, 2008 Author Posted January 29, 2008 the stair im buidling has two steel HSS stringer on the side....no post....n open riser....303.87 degree..but im using autocad 2005...what command should i use to build it? Quote
Mr T Posted January 29, 2008 Posted January 29, 2008 EXTRUDE (along a path appears in the command line) or SWEEP Nick PS This was discussed way way back in 2002. Quote
SLW210 Posted January 29, 2008 Posted January 29, 2008 Search on here for the Helix.lsp. This will draw the spiral then you can use ARRAY or MEASURE to arrange the blocks of the stair treads around the spiral and EXTRUDE>Path to do the stringers. If you could post a pic of what you want or a sketch, I will try to do a Tutorial with pics when I have time. Quote
