Extrude Points?

Rhino Rhino for Mac

Is there any way to extrude points to create lines?

I have sets of hundreds of coplanar points that I would like to create lines radiating from in the same direction.

If you are familiar with grasshopper there is a component that does exactly what you want:

‘Line SDL’ asks for a point, a direction vector and the desired linelength and generates lines from that.

Someone wrote a script to do this… I think @vittorio? or maybe @clement?

Try the attached Python Script.

import rhinoscriptsyntax as rs
def estrudi_punti():

rs.Command("_line")    #draw the line you want
line=rs.LastCreatedObjects()
ps=rs.CurveStartPoint(line)
print "ps"+str(ps)
points=rs.GetObjects("Select points",1)
rs.EnableRedraw(False)
print points
for point in points:
    vect=rs.VectorCreate(point,ps)
    rs.CopyObject(line,vect)
rs.EnableRedraw(True)

estrudi_punti()

btw @all, i totaly forgot this, in V6 you can extrude points into lines by using the gumball.

Oh, are there more goodies hidden under the hood for that reason we don’t know yet ?

You can tell us everything, we keep it a secret :crossed_fingers:

Well, you know how Rhino 6 for Windows lets you know when it’s 10 minutes to 5 and pours you a drink? Rhino Mac does not have that yet but I didn’t want anyone to feel bad.

Thanks all for the help. I’ll try these scripts out.

I have people anxiously waiting for me to draw some plans which has me waiting for the new Make2d which has me waiting for V6.

Hi, I am using this script at the moment, I have added _SelGroup to the start so I can auto select a group and extrude the points.

Can anyone tell me what would I would need to change/add to the script to automatically select the base point and move down the Z axis a set distance, eg. base point 0,0,0 and move along Z by 50mm?

Thanks,

Hi @jedhammerman, easiest is to create a button having this button command:

_Select _Pause
_-RunPythonScript ExtrudePoints.py 0,0,0 0,0,50

Note that you need to either provide the full path to the script or set a searchpath under:

_EditPythonScript > Tools > Options > Module search paths

Thanks Clement, that did the trick,

Although for some reason to move down Z 50 I had to use 0,0,0, 0,-50,0 ,
(I would have expected it to be 0,0,-50)

not sure why, but it’s working.
