Simple question: Click to create a point

bardlind · 27 Nov 2015, 14:28

Long time lurker and Sketchup user, first time poster. Hello!

I have finally gotten around to creating a little extension for Sketchup, which I will post later on. This is my first time coding in Ruby (and one of my first times coding, ever).

In the beginning of my script, I create two concentric circles which the rest of the code is based upon. For now, I have just entered the [x, y, z] coordinate for the center point manually. However, I would like to be able to do this:

Draw a line in Sketchup. Then select my tool from the extensions menu. Click the end of the line I just drew, and this point's xyz is used in my script as the center point.

I realize this is probably the simplest part of my script, but I have not been able to figure it out. Help is appreciated
