Thanks, gotit. Hope I don't forget!-)

@thomthom said: ............ 2. Exploding is very slow in SU. ( and if your script should fail at some point and halt - you're left with a broken model. ) ok! I changed my way and it seems work alot faster! (for my plugin converter 2 POV-Ray script). note: At this time I get only the color of the parent object(s) and not texture... def pov_find_faces(entities,tform,layername) entities.each do |entity| if entity.is_a?(Sketchup;;Face) pov_write_face(entity, tform) elsif entity.is_a?(Sketchup;;Group) if entity.material if entity.material.color $levelcolor[$level]=entity.material.color else $levelcolor[$level]=$levelcolor[$level-1] end if entity.material.alpha $levelalpha[$level]=entity.material.alpha.to_s else $levelalpha[$level]=$levelalpha[$level-1] end else $levelcolor[$level]=$levelcolor[$level-1] $levelalpha[$level]=$levelalpha[$level-1] end $level+=1 pov_find_faces(entity.entities,tform * entity.transformation,entity.name) elsif entity.is_a?(Sketchup;;ComponentInstance) if entity.material if entity.material.color $levelcolor[$level]=entity.material.color else $levelcolor[$level]=$levelcolor[$level-1] end if entity.material.alpha $levelalpha[$level]=entity.material.alpha.to_s else $levelalpha[$level]=$levelalpha[$level-1] end else $levelcolor[$level]=$levelcolor[$level-1] $levelalpha[$level]=$levelalpha[$level-1] end $level+=1 pov_find_faces(entity.definition.entities,tform * entity.transformation,entity.name) end end $level=$level-1 #UI.messagebox($level.to_s) end

tt, This recursive stuff really works! Below drills down into component instances. Now, on to add groups. def get_ci(ci_array) entities = Sketchup.active_model.entities entities.each do |ent| if ent.is_a? Sketchup;;ComponentInstance ci_array.push ent end end return ci_array end def explode_ci_array(ci_array) ci_sub_array=[] ci_array.each do |ci| if ci.is_a? Sketchup;;ComponentInstance ci_sub_array=ci.explode end end return ci_sub_array end ci_array=[] found = false while found == false ci_array=get_ci(ci_array) ci_array=explode_ci_array(ci_array) if ci_array[0] == nil found = true end end

All this time I labored under the belief that only old programs up to Win98 ran in the command window, and didn't ever try.

The file seem to be a config file of SU. @unknownuser said: // NOTE TO USERS: Making modifications to this file is not recommended as it will be overwritten // each time an upgrade is installed. I don't see much useful info in it for us... Possibly it could be used to brand SU - but as the file warns - it'll be overwritten upon SU updates...

@jim said: You may be able to use a PolygonMesh instead of adding each Face. The mesh will also be faster to create than individual faces; but which is better depends on your goal. See also: http://code.google.com/apis/sketchup/docs/ourdoc/entities.html#add_faces_from_mesh http://code.google.com/apis/sketchup/docs/ourdoc/entities.html#fill_from_mesh Yes I thank you, but I am working about some interfaces between SketchUp and other CAD system. At this moment I am unable to find the unique criterion that SkUp uses to dispense the order of the ponts in the mesh. Especially about faces edited by subtraction of other faces or with holes. The mesh is really difficult to decode because the vertexes seem to hop and to return using a lot of different combinations. This is really laborious and so I use to split triangular faces, that in CAD is a 4 vertexs faces with a duplicated vertex, or, where it'i possible, a couple of SkUp triangles that are a unique (cad) 3DFACE. Anyway I thank you very much, because I'll to import also textures, and I will need of the meshes also, I fear... Excuse my bad english..

ah, OK cheers Jim. It looks like it will be possible one way or another! now I know its possible, time to hunt down someone with the capabilities Thanks a lot for the help, Tom

hmm... that can be a problem with symmetrical objects like this - there are several possible ways to orient them...

My previous ruby file didn't even have the ./ to delete.in that script... tried for days to make it work. Cleared up now with this one ..Many Thanks :O)

Good question, hopefully soon. Now we'll have to add a version check to make sure people are not running SU 8, original release. But that's ok, the fix will be well recieved.

But it is a transient setting! If you click in the view it evaporates... It would be good if it were accessible but it is pretty transient...

Agreed. I logged several Feature Requests for MDI support (new methods) in the API, including a Models collection.

What makes it more troublesome is that the documentation doesn't mention bugs that appeared in the various methods in the various SU versions.

Never - my brain was being silly.

Wow, Sketchup.read_default and Sketchup.write_default were easy to implement. Attaching the defaults to individual models can also be advantageous, and I will have to think about the best way to save user defaults. Thanks guys. a_values=[] s_value="" s_value = Sketchup.read_default "honoluludesktop","values","None:Inches:Model:to Faces:by Number" a_values = s_value.split(":") . . results = inputbox prompts,a_values,enums,my_file_name+" Options" . . a_values = ["None",scale_sel,origin_sel,dface_sel,material_sel] s_value = a_values.join(":") result = Sketchup.write_default "honoluludesktop","values",s_value

TIG, As you suggest, I will work on this and post what I find. Thanks.

tt, and cf, Thanks. Got it to work as follows: my_definition.entities.transform_entities(t,my_definition.entities.to_a) Off and on for 4 days, this has got to be the longest time I've spent getting a single line of code right. Hopefully I'm getting better.

I unzipped a skm to see what it contained. If I learn enough, maybe working with skm's is something I can attempt to tackle a year from now?-)

I think it can be ported on OSX as zlib (library that I used in dezip) is available on OSX as well.
