Painting a quadrangular

[kolem]

I took the linetool.rb and tweaked it a little to fit my needs, and that was making a line and then hide it, the use for it if you have a quadrangular that sketchup cant 'paint' you make that line which makes 2 triangles that sketchup can 'paint'.
the thing is that when i draw that missing line it doesn't paint the 2 triangles?
any ideas?

SketchUp can't paint a quadrangular?
Can you provide an example?

[thomthom]

Oh wait - when you say 'paint' - do you mean it doesn't create the faces?

So you in some cases have a quadrangular that isn't co-planar - so you need an edge going across it?
With your tool - that creates the edge, call Edge.find_faces on the edge you create. That will make it behave like SU's native line tool and generate faces formed by the face if possible.

if its not on the same plane

[kolem]

yea that case,
how do i use Edge.find_faces

[kolem]

i looked at the example, and did this:

	myline=view.model.entities.add_line(p1,p2)
	myline.hidden=true
	face = entities.add_face(p1,p2)

not working, probably a syntax error.
any ideas?

You are trying to create a face with only two points.
The .find_edges leaves SU to create the faces. As you can see from the API docs - that method is called on edges. So you call that method on the reference to your edge.

Like so:
myline=view.model.entities.add_line(p1,p2) myline.hidden=true myline.find_faces

[kolem]

ok it works but I don't get the problem
whats the difference between find face and add face?

[TIG]

The method entities.add_face(..............) adds a face from three or more coplanar points/edges/etc that you specify - and only adds that face.
But edge.find_faces finds all of the faces that edge could have - these might be additional 'internal faces' in complex 3D form - as there could be several sets of coplanar edges that will 'take a face' - some of which you probably don't want!

thanks a lot!
