PythonScript Crash WIP

Serengeti (Rhino 8 BETA)

Hi Steve
In Rhino WIP when i use the below python script Rhino crash every time.
In V5 it’s Ok.

import rhinoscriptsyntax as rs
import Rhino
import System
def clipplaneYZ():
       
    pt_start=rs.coerce3dpoint((0,0,0))
    line_color = System.Drawing.Color.FromArgb(255,250,0)
    cp_color=System.Drawing.Color.FromArgb(255,0,250)
    vect1=rs.coerce3dpoint((0,30,0),(0,0,0))# punto o vettore va bene lo stesso
    vect2=rs.VectorCreate((0,30,30),(0,0,0))
    vect3=rs.VectorCreate((0,0,30),(0,0,0))
    def GetPointDynamicDrawFunc( sender, args ):       
        #***Disegna il quadrato che rappresenta il Clipping Plane
        args.Display.DrawLine( args.CurrentPoint,args.CurrentPoint+vect1, cp_color,2)
        args.Display.DrawLine( args.CurrentPoint+vect1,args.CurrentPoint+vect2, cp_color,2)
        args.Display.DrawLine( args.CurrentPoint+vect3,args.CurrentPoint, cp_color,2)
        args.Display.DrawLine( args.CurrentPoint+vect3,args.CurrentPoint+vect2, cp_color,2)
        args.Display(args.CurrentPoint)        
    gp = Rhino.Input.Custom.GetPoint()#creo oggetto gp 
    gp.SetCommandPrompt("Punto dove mettere il ClippingPlane")

    gp.DynamicDraw += GetPointDynamicDrawFunc  # chiamo in continuazione la funzione che mi mostra la linea dinamica
    gp.Get()   # qui ottengo i dati quando clicco     
    if( gp.CommandResult() == Rhino.Commands.Result.Success ):
        pt = gp.Point()  # qui ho le coordinate del punto del mouse        
        WYZP=rs.WorldYZPlane() #piano per clipping plane
        WYZP.Origin=pt       #origine del clipping plane
        cp=rs.AddClippingPlane(WYZP,30,30) 
        
    
clipplaneYZ()

Ciao Vittorio
