Hi:

After a trial run, the script was tested successfully. By setting the name suffix of Python Tag, the problem of repeated running of Tag can be solved.

Taking c4d.DIRTYFLAGS_SELECT as an example, if the point, line, and surface selections change, it will execute, otherwise it won't.

The Python script code is as follows:

import c4d
#e-mail: xiuziye@qq.com

def main():
       
    Name = op.GetName()

    Objects = op.GetObject()
    Changed = Objects.GetDirty(c4d.DIRTYFLAGS_SELECT)

    Text = ["xit" + str(Changed)[-1]]
    
    if str(Name).count(Text[0][:-1]) != 0 :
        
        if str(Name).find(Text[0][:-1]) != str(Name).rfind(Text[0][:-1]) :
            
            if str(Name)[str(Name).rfind(Text[0][:-1]):] == Text[0] :
            
                if str(Name).find(Text[0][:-1]) <= 0:
                    
                    #Do not execute, exit the program.
                    print ("Does not perform.")
                    op.SetName(str(Text[0]))
                    
                    return
                
                else:
                    #Do not execute, exit the program.
                    op.SetName(str(Name)[:str(Name).find(Text[0][:-1])] + str(Text[0]))
                    print ("Does not perform.")
                    
                    return
                    
            else:
                if str(Name).find(Text[0][:-1]) <= 0:
                    
                    op.SetName(str(Text[0]))
                    print ("Perform.")
                    
                else:
                    
                    op.SetName(str(Name)[:str(Name).find(Text[0][:-1])] + str(Text[0]))
                    print ("Perform.")

        else:
            
            if str(Name)[str(Name).rfind(Text[0][:-1]):] == Text[0] :
                #Do not execute, exit the program.
            
                print ("Does not perform.")
                return

            else:

                op.SetName(str(Name)[:str(Name).find(Text[0][:-1])] + str(Text[0]))
                print ("Perform.")

    else:
        print ("Perform.")
        op.SetName(str(Name) + str(Text[0]))
    


    print ("pass")
    #The next thing to execute.

HI:

I recently doing point cloud reconstruction, and it's really not a difficult problem. So the first thing you have to do is figure out 2 points and the center of the circle, so there are 3 points.Then figure out the length of each side of the triangle surrounded by 3 points, and finally figure out the Angle between 2 points and the center of the circle.You plug in the arc length formula and you get the arc length between 2 points.
