Edges problem

jorre

hi
i'm working on a project where i have to copy some objects to another layer..
mostly it are rectangle objects..
with these objects there is no problem..
but i also need to copy walls.. but the walls aren't rectangle objects, because in my project they have 76 startpoints of the edges..
you can see in the code that only objects with attributes get a copy..
but in the picture i marked the part of the wall that has got an attribute, and the part that doesnt have an attribute.

i dont really understand why sketchup copy's the side of the wall instead of the top of the wall.. i think there most be something wrong with my methode of copying the edges..

maybe someone knows where there is an error in my code

model = Sketchup.active_model
	entities = model.active_entities
	layers = model.layers
	new_layer = layers.add("Preview layer")
	group = entities.add_group
	group.layer = new_layer
	gentities = group.entities
	entities.each do |entity|
		if (entity.typename == "Face")		
			edges = entity.edges
			edges2 = Array.new
			edges.each do |edge|
				p1 = edge.start.position
				p2 = edge.end.position
				edges2.push(gentities.add_line(p1, p2))
			end
			face = gentities.add_face(edges2)
			context = entity.get_attribute "locon", "context_info"
			if(context != nil && face != nil)
				face.material = $context_info_color[context]
				face.back_material = $context_info_color[context]
			end
		end
	end
	pages = model.pages
	page = pages.add "Preview"
	activelayer = model.active_layer = layers[2]
	layer = model.active_layer
	layers.each do |layer|
		if (layer.name == "Preview layer")
			page.set_visibility layer, true
		elsif
			page.set_visibility layer, false
		end
	end
	group.locked = true

First make an array of all active faces...
Then go through that and make a reduced array of faces+attributes...
Now process the list of found faces...
Perhaps, copy/move the faces' edges into the group and group.add_lines...edges.find_faces, for the set, as you go - no need to find all the vertices ?

Seems your present code copies all faces ?

all the faces where there is an entity (attribute)

entities.each do |entity|

before i copied all the faces into a group, but for some reason sketchup forgot to copy all of the objects.. there where usualy 2 or 3 faces that didnt get copied into the group.. but they had attributes

Let's try to copy all faces into the group first... then we can look at sorting the 'attribute' filtering... I can't see what's up. Skip the attribute parts and first see if you can copy all faces into the group faultlessly...

jorre

i left out the part of coloring the attributed items..

still only top of the walls don't get copied?
so why doesn't all the edges get copied into the group except te top of the walls?
because i use every point of all the edges?

doesnt face = gentities.add_face(edges2) work like it should?
or don't i use it correctley

edit::

i now changed something in my sketchupdesign..
i made the top of the wall smaller area's..
originaly the walls was one big area..
nog lets say every area has 4 different wall's..
and now it works like it should..

but it isnt very good for the usage in sketchup..
i think is must be possible to draw the whole big area..
but how?

jorre

Is there maybe a way to divide an object into triangles?
because the add_face instruction can draw traingles..

is there a function for this?

thanks
