Model Stair Stringers in Tekla
Without the correct type of help, the use of Tekla can a difficult skill to master. If you would like assistance with Customization, Custom Components, development of projects, or even the carrying out of main projects, drop me an “e” mail on email@example.com
I have found this the best way. It's very similar to the way I would do it in 2D cad. Should anybody have a requirement for any stair parts ie treads, stringers, handrailing etc. please give me a call and I'll get you a quote.
1) Draw in grids as shown plus on plan for outside of stringers.
The above sketch is taken from drawing ACW_01 Vietnam job. Treads are 275 mm wide 30x5 flat pitched at 33.75 mm.
Open Treads from plain plate, durbar and perforated plate.
Go to profile catalogue>others pick BLZ
insert these values BLZ280*100*5 this is assuming plate is 5 mm thick.
Spiral Stair for info on this go to
Used Tekla connections con 19 & 21 for spiral section on above stairs. It was a compete waste of time it doesn't do anything to produce the detail drawings. I've done all other jobs in 2d autocad. JOB CAL.75 Dance Studio Calder Fabrications.
