Need help to select id with python

Hi all of you genious out there .

I’ve this script that I need to improve a bit.

! _-RunPythonScript (

import rhinoscriptsyntax as rs

curve = rs.GetObject(“Select a curve”)

if rs.IsCurve(curve):

print "Curve dimension =", rs.CurveLength(curve)

l = rs.CurveLength (curve )

start = ( 0, 0, 0 )
end = ( l, 0, 0 )

base= rs.AddLine(start, end)

turns =rs.GetReal(“n of turns”)
point0 = (0,0,0)
point1 = (l,0,0)
pitch = l/turns
radius0 =rs.GetReal(“spiral radius”)

spiral01= rs.AddSpiral(point0, point1,pitch, turns, radius0, )
spiral02 = rs.RotateObject((spiral01), (0,0,0), 180, (1,0,0), copy=True)

cmd1 = ( 'Scorri ( copy = False) Selid ’ + str( spiral01 )+
’ Invio Selid ’ + str( base ) + ’ Selid ’ + str( curve ) )
rs.Command( cmd1 )

cmd2 = ( 'Scorri ( copy = False) Selid ’ + str( spiral02 )+
’ Invio Selid ’ + str( base ) + ’ Selid ’ + str( curve ) )
rs.Command( cmd2 )

cmd3 = ( 'Selid ’ +str(spiral01))
rs.Command(cmd3)

cmd4 = ( 'Selid ’ +str(spiral02))
rs.Command(cmd4)

cmd5 = ( 'Selid ’ +str(base))
rs.Command(cmd5)

rs.Command(’_delete’)

cmd6 = ( ‘Selid ’ +str(curve))
rs.Command(cmd6)
rs.Command(’_hide’)

crv1 = rs.GetObject(“sel crv1”)
crv2 = rs.GetObject(“sel crv2”)

radiusp= rs.GetReal( “raggio pipe” )
rs.AddPipe(crv1,0,radiusp)
rs.AddPipe(crv2,0,radiusp)
)

So basically what it does is to create a rope kind once a curve is selected .

You pick the curve it will make a line of the same lenght and wrap it with a spiral. Then flow the spiral using the line as base crv and the input curve as target crv.

last it will prompt to select the two new spiral that are been created around the original curve and ask for a radius to pipe them.

My question is how do I get the ID of those two new spiral so that it’s no more necessary to select them manually ? … I’ve tryied many ways with no result .

Any idea ?
Any help?

thanks a lot,
alberto

Ciao Alberto

I think I don’t understand exactly which are the curves …
Are they those created by cmd1 and cmd2 ?

Ciao

Ciao Emilio ,

Yes …correct . The curves created with cmd1 and cmd2.

I think i’ve got finally a solution using the rs.lastcreatedobjects

I’ll post soon result for who is interested.

If you have any other suggestion , please , let us know .

Ciao

Yes, that usually works . :slight_smile:

BTW, If the command only creates one object, you might also use
rs.FirstObject()
