Get object coordinate

Hi everybody.

I’m try to modeling geometry object using ruby API.

then while, i need get the coordinate of some object.

i was find some method of get coordinate by event(mouse clicking)

but i need the without user interaction.

for example

white circle is cross section points.

how can get coordinates of white circles coordinates?

You need to go through some tutorials and books.
There are some that are specific for SketchUp.
