I hadn't seen that i could put a different material to each instance of a same defintion
thanks a lot ! it works very well

I have read all you optimisation tips and tried them, but nothing seems to change the speed creation of my objects. I'm using Sketchup 8 to create dominos described by a picture. To create the dominos, I tried the add_face method and the fill_from_mesh, but the times are exactly the same. It takes me about 2 s to create 400 pieces, and it's growing exponentially. With 600 pieces -> 7s, 1200 pcs -> 50s...
Is it normal to take so much time ? Each domino is created in his own group for the moment, but it doesn't change if I create them directly in my scene.

In my array I have groups, that I get from a top to down traversal. I think the best solution will be to store my own couple (transformation,group) in my own tree structure to do the thing I need.

In fact, I'd like to add a physical engine created by our society to sketchup, like sketchy physics does.
So each entity in sketchup is linked to a body in my engine. I have the list of the linked entity in my own array so I can access them through this array.

When I make my simulation, to initialize value, I have to get the whole transformation of my entities to set their position in the physical world, and then at each step I get the transformation in my engine and have to set it to sketchup entity, but if they are in a group (for example a group bike, we'd like to turn the wheels) I have to extract the wheel transformation of the bike transformation, as the wheel's transformation depends on the bike's transformation.

Hello everybody,

I've got a little problem in sketchup.
I'm parsing all the elements from my Model, using the entities method, to go from the model, to the group, to the face, to the position....It's for me a top-down traversal so I can get all the transformations of my elements. This works great.

But now, I need to do the reverse, I've got an entity, and I want to get all his parent's group transformation, but when I use the parent method on a Face for example, it takes me to a DefinitionList, which is directly in the model, I can't get the parent group and his transformation. Sometimes, it works using the instances method on the DefinitionList to get the group that uses this definition, but if many groups shares the same definition, I don't know which one is the selected one.

If somebody can help me, it would be great

thanks in advance and sorry for my bad english :s

I just wanted to put the vertex in the selection for drawing considerations, but I'll do it in an other way.

For the moment, I'm trying to found a memory leak when I try to send my mouse coordinates to a Webdialog for displaying it using the InputPoint class and the position method. It takes me a lot of memory and then makes sketchup very slow.

		#quand on bouge la souris
		def onMouseMove(flags, x, y, view)   
			#mise à jour du point deplace
			@input.pick view, x, y	
			
			update
			
			view.invalidate
		end
		
		def update
			pt = @input.position
		end

it looks like this with some javascript call in the update function

but when I comment them, there is still the leak. If you move a lot your mouse, you'll see the bug

ok thank you for your fast answer.

I'll try to fit my needs into antoher way, your Vertex Tools looks great, but it isn't adapted for me.

Hi everybody,

for my first message, I've got a problem in Sketchup and Ruby.
I'm trying to modify some Vertex position, I access them through the vertices method in the edges, so myVertex is a Vertex

				
if myVertex.is_a?(Sketchup;;Vertex)
     puts "Vertex"
     if myVertex.is_a?(Sketchup;;Entity)
          puts "Entity"
     end
end
			
if myVertex.is_a?(Sketchup;;Entity)
     Sketchup.active_model.selection.add myVertex
end

this show me in the ruby console :

Vertex
Entity
Error; #<TypeError; wrong argument type (expected Sketchup;;Entity or Array of Sketchup;;Entity)>

when i try to add it to the selection.
so I've got a Vertex which is an Entity, and it says me that it's not an Entity (with the error)

Can somebody explain me this symptom please ?
thanks

(sorry for my english)
