def sp():
    try:
        a = uidoc.Selection.PickPoint(ObjectSnapTypes.Endpoints,"Please select point")
    except:
        a = "NA"
    return a

class pickPoint(Form):
    def __init__(this):
        this.button1 = Button()
        #
        #button1
        #
        this.button1.Location = System.Drawing.Point(288, 129)
        this.button1.Name = "button1"
        this.button1.Size = System.Drawing.Size(150, 34)
        this.button1.TabIndex = 0
        this.button1.Text = "Please Pick Point"
        this.button1.Click += this.button1Click
        #
        #Form1
        #
        this.ClientSize = System.Drawing.Size(452, 196)
        this.Controls.Add(this.button1)
        this.Name = "Form1"
        this.StartPosition = System.Windows.Forms.FormStartPosition.CenterScreen
        this.Text = "pickPoint"
        this.ResumeLayout(False)

    def button1Click(this,sender,e):
        this.p = sp()
        this.Close()

form = pickPoint()
Application.Run(form)
OUT = form.p

Hi,

Seem work fine

test pickpoint

Note:
in python the name of the parameter which corresponds to the instance is ‘self’ by convention not ‘this’

Hi,

I Keep same code and changed “This” to “Self” but when click to button of Form, not get API menthod.
In the first time to click LeftMouse, not get API menthod. must press to scond time

If want Snap point before pickpoint I must press mid of mouse 2 times then can be snap points of element in Revit.

Last of video you can see, I used C# to pick point (result I can ObjectSnapTypes.Endpoints)

maybe there is a conflict with an add-ins, try to dispose the form at the end

But as you said “maybe there is a conflict with an add-ins”, my code OK in my computer.
