AddPolyline problem, got Tuple?

Grasshopper

Can anyone help me with the way I typed this:

myQuad = rs.AddPolyline([a[(i,j)], a[(i+1,j)], a[(i+1,j+1)], a[(i,j+1)], a[(i,j)]])

it comes up with expected index value, got tuple

see screen shot, won’t run

Thanks, Mike

Hey, what’s the solution? I’m running the same tutorial and can’t figure out why I’m not getting the polylines!

Hello,

I think you need something like i*numV +j instead of (I,j)

i just figured it out too. if anybody else is doing this Mode Lab tutorial and finds this, it’s because he opens a script that’s slightly different from the previous video’s version but doesn’t mention two important changes:

  1. it changes from a = [ ] to a = { }

  2. the previous script ends with a.append(myPoint) but in the new script that line is changed to a[(i,j)] = myPoint

Epic fail!

another solution is

for i in range(numU+1):
    aa=[]
    for j in range(numV+1):
        get new point
        aa.append(newpoint)
    a.append(aa)
for
    for 
        myQuad=rs.AddPolyline(a[i][j],a[i+1][j]....)
        cells.append
