Hoping someone can point out a direction for this.

Am trying to cycle through all the layers in the rhino model and in each layer, to join the meshes.

so far,
Code:
rhinoscriptsyntax.GetLayer (title="Select Layer", layer=None, show_new_button=False, show_set_current=False)
might work, but requires manually selecting the layers.

any ideas?

Thanks in advance... ]]> RhinoPython llennardd http://python.rhino3d.com/threads/1392-Get-all-layers How to create point arrays following the edges http://python.rhino3d.com/threads/1391-How-to-create-point-arrays-following-the-edges?goto=newpost Tue, 21 May 2013 12:37:40 GMT Hi, I would like to create point array on a free form surface which depend on edges.

I would like to create point array on a free form surface which depend on edges.
The example geometry is shown in geometry.png.

If I use the surface domain and evaluate points on the surface domain, for example:

for i in range(rows):
s = u[0] + ((u[1]-u[0])/(rows-1))*i
for j in range(cols):
t = v[0] + ((v[1]-v[0])/(cols-1))*j
# find the points on the surface using the surface domain u v coord
pt = rs.EvaluateSurface(srf, s, t)

I get the points along the nurbs surfaces as in Fig. geometry2.png. What I need is a (mostly rectangle) array of points, which follow the edges of the geometry as in Fig. geometry3.png

1- in U V domain, and
2- equidistant in x and y directions projected to the surface (not in U V domain.)

Thanks in advance,

And tried to see if that problem could be solved in the following way:

When "x" input plug of GH component changes, the "a" output plug should generate "True" and after half of a second "False".

This is the code I used:

python Code:
    import time
     
    if len(x)>1:
        a = True
        time.sleep(0.5)
        a = False
    else:
        a = False

But this code always ouputs "False" no matter what happens with the condition. Never "True".
I even tried adding a grasshopper "Record" component onto the "a" output plug - still always get the "False".

What am I missing here, an is this solution completely incorrect?

I attached the whole .gh definition.

Thank you for the reply.

I have a problem with my python editor in Rhinoceros 5. I was trying to install numpy and scipy and accidentally I removed all the path directories from the editor options menu.

i attached a slightly double curved surface that i used to debug this.
Somehow I'm getting different results unrolling the surfaces with the script command and unrolling it via the commandline. In general, rs.UnrollSurface() yields worse results, when comparing the surface areas of the unrolled geometry to the original. The testfile is in meters, when I change the file units to mm, the result is much better.
How can I get the precise result in my meter-file? I tried changing document tolerances, but this didn't seem to affect the results of the script command. For now, I will use the commandline, but it would be nice, to get the rs-function to work properly.

Here's the code I used to unroll and compare surface areas:
Python Code:
    import rhinoscriptsyntax as rs
     
    strID = "73350afd-2fbc-4fea-9237-364476ef7081"
     
    strCommand = "_UnrollSrf _SelID " + strID + " _Enter"
    rs.Command(strCommand)
    srfUnrollCommand = rs.LastCreatedObjects()[0]
    srfUnrollScript = rs.UnrollSurface(strID)[0]
     
    numAreaOriginal = rs.SurfaceArea(strID)[0]
    print(str(numAreaOriginal)) + " Area original surface"
    numAreaCommand = rs.SurfaceArea(srfUnrollCommand)[0]
    print(str(numAreaCommand)) + " Area command surface"
    numAreaScript = rs.SurfaceArea(srfUnrollScript)[0]
    print(str(numAreaScript)) + " Area script surface"

My classmates and I developed a script that links to a twitter account. When that account receives a mention, it generates geometry based on the text in the mention, and then tweets a picture of that geometry.

The only problem right now is that I need to have my laptop running Rhino and the script 24/7 for it to work. I'd like to find a place to host this (hopefully inexpensively) so it can be active all of the time without me needing to sacrifice my machine. The potential problems I see are that the cloud system must have Rhino 5, and we would need to install some python libraries that we edited to get it to work properly.

Any suggestions? Thanks!

Here is the code I am executing in RhinoPython Editor:

python Code:
    for number in range(5):
        print number,

Interestingly nothing appears in the console.
But when I remove the "comma":

python Code:
    for number in range(5):
        print number

I get the desired result (printing the range function array in the same line) along with the new (expected) array in each line:

Code:
0 1 2 3 4 0
1
2
3
4
Why is this happening?
