personalised Tread and Risers

Anonymous

Trying to create RISERS in metal steels (with holes) & TREADS in a metal plate type surface.

Tried BIM library- no good - plus not sure how to edit these GDL files to fit.

thank you all..

Hello atfonit,

I think you should consider your projet cumber of polygons before modeling it like as build.
It might be very heavy to use !
I invite you to try with complex profiles into Options menu.

Thanks, fyi - the image is not my file but one I have saw online.

Tried with complex profiles editing an existing steel U beam. The only problem is how to create the holes in the complex profle as it's a section, holes in the section profile don't work. This is the RISER we are refering to. (Contramarche.)

The TREAD/marche, I can't seem to see how to have this metalled grilled pattern. I dont jsut want to change the surface - I want it so the material itself becomes a metal grated plate for the tread.
I do not modelise this kind of detail 😕
I think you have to do it with GDL !?
Or with SEO but it will be hard to model and even more to modify.

If you are using the stair object you can create custom risers and treads by converting one to a morph and then saving back as a tread or riser.

These may help - the focus on treads but I am sure the same can be done for risers.

The holes in the riser probably won't hurt the model (speed) too much.
But the mesh tread might.
I would use a surface material that has a mesh look with alpha channel so that it will render transparent but still be a single solid surface in Archicad.

ThanKs Barry, yes have done the SAVE AS as riser / tread after convertinbg to Morph but cannot seem to create the hole in the steel, which was a complex profile (see image). Tried boulean object and subtract from solid object.

Wouldn't you convert it to a morph, cut the holes in it (by editing morph or maybe by Solid Element Operation?) and then save it back as a tread/riser?
I don't think it will be very parametric if you need to adjust the width of the stair for example.
I think you would need to script the riser/tread to make it parametric.

The first suggestion i tried - i.e. to cut hole in both options (solid element operation & editing the morph). Both seem problematic for diffeent ressons, and neither worked.

"scripting the riser" - perhaps something i need to look in to doing. Dont know how ?
will google it as well.

I just quickly tried.
Set complex profile for all risers.
Select one (lowest one is best) and convert to morph.
Place some beams and did Solid Element Operation for holes.
Resaved as morph so the holes are locked in and beams can be deleted.
Select morph and save as library part - riser.
Set stair to use the new riser.

If you are not familiar with GDL scripting I would not even try this.
