Handle _Paste command with GetPoint class (the GetBaseClass -> GetString,...)

Rhino Developer

Hello,

I spend a bunch of time trying to collect data send by _Paste command during the execution of the GetPoint class into a loop. The loop is working by entering values manually, but not with the _Paste command.
My goal is to immit the _Points command.
See the capture bellow.

I’ve tried almost every GetBaseClass methods unsuccessfully. (AcceptNothing, AcceptString, EnableTransparentCommands, AcceptEnterWhenDone, …)

I’ve tried with :
Rhino.Input.RhinoGet.GetPoint object
Rhino.Input.Custom.GetPoint object
rhinoscriptsyntax.getPoints → which use the RhinoCommon API as well

I’m all available to discuss this issue, thank you so much for your help.

The code trials down here:

#with RhinoGet
string = “enter points”
import rhinoscriptsyntax as rs
import Rhino.Geometry.Point3d as Point3d
import clr
import Rhino
outPoint = clr.StrongBoxPoint3d
points =
bool = Rhino.Input.RhinoGet.GetPoint(string, True, outPoint)
while bool == Rhino.Commands.Result.Success:
point = outPoint.ToString()
print(point)
points.append(point)
bool = Rhino.Input.RhinoGet.GetPoint(string, True, outPoint)
rs.AddPoints(points)

#with Input.Custom
string = “enter points”
gs = Rhino.Input.Custom.GetPoint()
gs.SetCommandPrompt(string)
# gs.SetDefaultString(string)
gs.AcceptEnterWhenDone(True)
gs.AcceptNothing(True)
gs.AcceptString(True)
gs.EnableTransparentCommands(True)
gs.Get()
# gs.GetLiteralString()
points = [gs.StringResult().Trim()]
while gs.CommandResult() == Rhino.Commands.Result.Success:
gs.Get()
prevString = gs.StringResult().Trim()
values = prevString.split(“,”)
if len(values) == 3:
points.append(map(float, values))
rs.AddPoints(points)

Up !

This seems to work pretty good:

import Rhino
import scriptcontext as sc

def test_point_paster():
    points = []
    gp = Rhino.Input.Custom.GetPoint()
    gp.SetCommandPrompt("Location of point")
    while (True):
        gp.Get()
        if (gp.CommandResult() != Rhino.Commands.Result.Success):
            break
        points.append(gp.Point())
        gp.SetCommandPrompt("Location of point. Press Enter when done")
    
    for pt in points:
        print(pt)

if __name__ == "__main__":
    test_point_paster()

Thank you very much Dale for the answer. I just tried it in Rhino 6 without success, do you use Rhino 7 maybe ?

I tried it on Rhino 7 without sucess. It seem’s that the 'Paste command behave in a particular manner.

If anyone from Mc Neel can tell us more about it.

Thank you,

An alternative to solve this issue is to use the Grasshopper Player. You can copy a part of your code in a GH Python block and use the new blocks from Rhino V7 :

  • Get Point
  • Get String

You can _Paste whater you want during the prompt of those new blocks.

Refer to this Steve Baer’s tutorial for more information:

As the paste command is available from the Grasshopper Player, it would be great to have the code allowing it ?

I didn’t find anything related to that in the API.
