Repeat lines

1

Good companions.
I would like to ask for help, I want to make a staircase, but I do not know how I can repeat these lines constantly one over the other as seen in the red lines, I appreciate if you can give me a guide on how to develop it, thanks.

Try this one.

I would recommend you model a full tread and riser, and then use a list of coordinate systems to transform that base geometry into place.

hello,
Continuing your code block
here is a another possibility

code block :

p1=Point.ByCoordinates(0,0,0);
p2=Point.ByCoordinates(1,0,0);
v1=Autodesk.Vector.ByCoordinates(0,0,1);
t1=Autodesk.Geometry.Translate(p2,v1);
l1=Line.ByStartPointEndPoint(p1,p2);
l2=Line.ByStartPointEndPoint(p2,t1);
n;
dx=Autodesk.DesignScript.Geometry.Curve.Length(l1);
dy=Autodesk.DesignScript.Geometry.Curve.Length(l2);
Autodesk.Geometry.Translate(l1,(1..n)*dx,0,(1..n)*dy);
Autodesk.Geometry.Translate(l2,(1..n)*dx,0,(1..n)*dy);

Thank you very mush

steps

PolyCurve.ByPoints (List.Flatten (Point.ByCoordinates (List.Cycle ((0..#cnt..trd)<1>,2), 0, List.DropItems (List.Sublists (0..#cnt+1..rsr,0..1,1),-1)), -1));

thank you very much for answering, I would like to know how I could put points in all the vertices of my polycurve, this in order to join them and start generating my solids, thank you.

Hello, your stair nosings are the indexes (odd: 1,3,5,…) of Mr. Vikram’s solution
(you do a List chop of 2, then last item with the right lacing)

if you want to draw the bench (even index: not necessarily all)

Cordially
