It's odd that it happens on the second File->New as in the first one, nothing is done. And yes, I do have quite a few observers and references. Though, I thought I was resetting everything onNewModel. I think I'll have to release a developers alpha, see if anyone can spot the culprit in my code. What I'm building is a plugin that allows cutout components to also cut through an opposite faced face. It does taht by creating a new invisible cutout. That's the simple stuff. The complicated stuff is making sure the extra cutout syncs with move,rotate,edits etc. That required allot more work than expected. Especially since I ran into so many bugs in the SU Ruby API requiring workaround upon workaround.

I looks like it's some wires crossed in the backend. I made a typo when I wanted a DefinitionsObserver, where I instead wrote DefinitionObserver. But the code still worked. So while the DefinitionObserver doesn't trigger the events it's supposed to, it triggers all of DefinitionsObserver's events. Example code: class TestDefinitionsObserver < Sketchup;;DefinitionsObserver def onComponentPropertiesChanged(definitions, definition) puts 'DefinitionsObserver - onComponentPropertiesChanged' end def onComponentRemoved(definitions, definition) puts 'DefinitionsObserver - onComponentRemoved' end def onComponentAdded(definitions, definition) puts 'DefinitionsObserver - onComponentAdded' end end class TestDefinitionObserver < Sketchup;;DefinitionObserver def onComponentPropertiesChanged(definitions, definition) puts 'DefinitionObserver - onComponentPropertiesChanged' end def onComponentRemoved(definitions, definition) puts 'DefinitionObserver - onComponentRemoved' end def onComponentAdded(definitions, definition) puts 'DefinitionObserver - onComponentAdded' end end module TestDefOb def self.test r = Sketchup.active_model.definitions.add_observer(TestDefinitionObserver.new) puts 'Sketchup;;DefinitionObserver - ' + r.to_s r = Sketchup.active_model.definitions.add_observer(TestDefinitionsObserver.new) puts 'Sketchup;;DefinitionsObserver - ' + r.to_s end end Type TestDefOb.test in the console and add/remove some component definitions. Notice how both observers trigger.

@jderekito said: Thanks TIG, The defaulting to inches explains it. For now I am just trying to draw a single line. If I just drawing a single line does it still need the face and edges. Thanks again for you assistance as I am still learning my way around SU. Derek 'Line' and 'Edge' are interchangeable in this context... A line [edge] is just a line. edge=entities.add_line(pt1,pt2) for one line, edges=add_edges(pt1,pt2,pt3); edge0=edges[0]; edge1=edges[1] for multiple lines [edges] strung between the list of points - if you use .add_edges you get an array of edges - if there's only one you still need to use edges[0] to find it, if you .add_line you get just the one edge [line]. A face needs at least 3 edges with common vertices. More edges also have to be coplanar. face=entities.add_face(xxxxx) takes a 'list/array of points', it then makes new edges with a new face, or a 'list/array of edges', or a 'closed-curve' - it then makes a new face to these existing edges So there are several ways: Make the points and then make the edges and face in one go - probably what you want - face=entities.add_face(pointsList) Make the edges from the points and add the face to them - useful if some edges pre-exist - edges=entities.add_edges(pointsList); face=entities.add_face(edges) Make the edges and then 'find_faces' that they can have - useful if it's a set of 3D edges - edges=entities.add_edges(pointsList); edges[0].find_faces it returns only the number of faces that it's made - if you want to find the face itself then you then need to use face=edges[0].faces[0] additionally...

Why not write us one...

Hello TIG, Again many thanks for the hint. sel_def.instances[0].add_entities(MySubCompArray) does the job for me. Now I can use the imported dummy-block from autocad as the hierarchy-master instead of creating a separate new group. Will keep the outliner structure more readable. I also use now Jim's togglewindows.rb to keep the outliner close during execution.

The onContentsModified event is broken...

Ok. Found the problem. I was using model.active_path to cache the last path. When the last path was the model itself it'd return an empty array.

@aceshigh said: well, I am certainly getting depressed for the lack of the plugin Maybe this could help you to fill 'un-depressed' (and therefore 'pressed') http://www.sketchucation.com/forums/scf/viewtopic.php?f=180&t=18916#p155058 Fredo

NO. Use Plugins >> Component Report++++

Adam, Thanks for the script. I wasn't aware of Sketchup.open_file(url). Does it open a new instance or does it replace the open file?

Unfortunately, as you say, a group is not a component ! The group.make_unique is 'deprecated' BUT it works till it's fixed by Google... Why don't you make the group into a component, THEN you can probably use it as desired - inst=group.to_component - returns its instance OR defn=group.to_component.definition - returns its definition if you want to add to that... OR instn=defn.instances[0]to return what you just 'componentified' from the group...

Works fine on my PC with Vista. Opens an app (.exe) or a file with it's assigned app... Puzzling...

@unknownuser said: Ruby is kind of cool in that you can increment Strings. Thanks Jim for the tip. In this case I can not use it, since my block-numbering-steps comes from the imported autocad-blocknames. But maybe it gets usefull in the future. @unknownuser said: Do whatever works for you best... Thanks again TIG. Hans-Peter

The sample 'Make Sang Red' from here: http://www.sketchucation.com/forums/scf/viewtopic.php?f=180&t=17888&p=145120&hilit=Make+Sang+Red#p145120 might help: # Add a new configurable option to Sang. # (Any attribute that starts with an underscore # is a "meta attribute" that describes behavior.) sang_def.set_attribute 'dynamic_attributes', 'weight', '145' sang_def.set_attribute 'dynamic_attributes', '_weight_label', 'weight' sang_def.set_attribute 'dynamic_attributes', '_weight_formlabel', 'My Weight' sang_def.set_attribute 'dynamic_attributes', '_weight_units', 'STRING' sang_def.set_attribute 'dynamic_attributes', '_weight_access', 'TEXTBOX' Not sure if this would enough to make a normal component into a DC! Will try.

Oh! Deception So translator must be very brief

Fredo, did the pic come?? i'll re-attach. freeScale. bottom box after TopMenu your delightful scripts, when I can download them (a problem with this site), and get them in the right place (my fault) are fantastic to use on the Mac, my comment was more about if any of the earlier ones had been absorbed into FreeScale or Pushpull, or outdated by SU7, etc.. then I will not try to find them now. cheers john [image: oPgQ_monpm2.jpg]

Too funny....your quick Chris. When I have a minute....which might be awhile, I'll put together a little Photoshop idea of the dialog box. It might help. And I can't believe your not a math whizzzz. I was checking out your Ruby writing tutorial. Can't wait to try it. You've made it look really user friendly. Have a great day! Jeff

pret auto How wonderful feedback!
