Hi guys,
I use the following code to set the center point = position of the mouse click:

def onLButtonDown(flags, x, y, view)
puts " x = "
puts " y = "
puts "--------------------- "
centerpoint = Geom::Point3d.new x,y,0

However, the (x,y) seems not to be my mouse's click position. It is just random.
How could I set the center point to be my mouse click position?

Hi,
May I know after determining if the 2 groups/ components/ faces are intersected. How do I get the area of the intersection?

In other words, my question is:
How to create a new face/ entity (or whatever) that hold intersection of A and B so that I can then use the area() method to get the area of that intersection.

Hi everyone,
Please take a look at the attached image. Here is the situation:
I have only a rectangular.
Using SketchUp, I can easily draw a circle, select the intersection of my circle & rectangular --> view Entity info --> I can see the area of the intersection.

However, I want to write a ruby script to automatically draw the circle, then get the intersection area.

I can automatically draw the circle, no problem. However, I don't know how to automatically get the intersection area. May I know if there is any function in Ruby API can do that?
There is a face.area() to get the area of the face, however, I don't know how to define the face = intersection. Is there any way to do that?

Thank you.
