Asking For Help Points are not planar (resolved)

[Mcdull]

i am trying to read polyline from xml document,then to generate three-dimensional wall.now there is a problem that just lines in the X direction can be drawn,the others in the y direction can not be drawn,and show a message that
Error: #<ArgumentError: E:\test\RubyApplication1\lib\main.rb:250:in `add_face': Points are not planar>

// if i draw the lines in the y -direction by it self,it can be done, i dont know why?pelese help me!
thank u very much!

Would help if you enclosed your code in the CODE tag so it doesn't get smileys in the code - and it will preserve formatting. And with such a long code it's probably easier to just attach it.

ok,i have done.thank u

Have you outputted the loopVertices to the Ruby Console content before passing on add_face? Just to visually inspect the data?

Have to look further into what the code does before I can say anything more.

But this code, right before line 250.

loopVertices = []
for v in loop
  loopVertices.push([v.x,v.y,v.z])
end

Should that not say for v in loop.vertices ?

I gather that you want an array of 3D points?

That can be written:

loopVertices = loop.vertices.collect { |v| v.position }

Vertex.position returns a Point3D for that Vertex.

yes ,i have inspected all the loopvertices to the Ruby Console content,every wall has 6 faces.
but if passing on add_face,the error will come out with the message points are not planar.
Vertex.position returns a Point3D for that Vertex.

I think I got that error sometime when I had only 3 points. I thought there must be some mistake as any 3 points are planar. I found out later that the 3 points were in fact linear, and thus not planar.

Maye this is what is happening?

pts = [ [0, 0, 0], [1, 0, 0], [2, 0, 0] ]
Sketchup.active_model.entities.add_face pts
Error; #<ArgumentError; (eval);65;in `add_face'; Points are not planar>

when i generate 3d wall,some points are not planar.i have changed the function.
