@tig said: Googling 'dxf reference guide' return lots of interesting hits - e.g. http://www.autodesk.com/techpubs/autocad/acadr14/dxf/dxf_reference.htm Also there are several RB file plugins in the PluginStore which do DXF import/export manipulation - so using those as 'cribs' would help too... So what more do you want ? Thanks for this... i did a lot of search, but I guess I used the wrong keywords ) never found this. Thanks a lot.

@blruuska said: Dan, Thanks for verifying. It is surprising that NotImplementedError wasn't raised, if that is the case here. Ackh! Yea, something is amiss here. Not sure if we intended to support enumeration type in the initial release of the API - but if that's the cause it should have been NotImplemented. However, I might confuse this with the "choice" type. Maybe something changed in the last moment. I need to investigate.

Thanks TIG and Dan I applied the code to the Tails part of my Dovetail Tool and now the result is a part with tails that is still a solid. No left over edges or faces. The strange thing was that when selecting the component edges if you selected them clockwise (edge1 to edge2) the part was clean but selecting in a counter clockwise direction there were left over faces. Now thanks to your help edge selection direction works either way. Thanks Keith

@tig said: I don't have time to dissect your code in detail... But it seems to me you are replicating my Latticeizer plugin ? Look at that... http://sketchucation.com/pluginstore?pln=Latticeizer You need to offset the perimeters of the edges' faces [which sometimes fails, just like native-offset - so it perhaps needs my Smart_Offset?] It's NOT easy... Don't waste your time dissecting it since this is a just for fun exercise. I have found a number of bugs but have a few more to go. I have no intention of publishing it since, as you say, there is Latticeizer and others already out there.

SketchUp 2014 was bugged in this regard. The workaround was to pipe to a text file, I think. I think it was fixed in SketchUp 2015. I recall having written a patch script that overrode the Kernel.backquote method. (I have to have a look for it.)

A good question for: http://forums.chaosgroup.com/

@wawmsey7 said: However it would be easier if I could have code before the code for loading the component to check if it's already loaded or not into the model and then load it if it's not already there? Is that do-able? You need to search the DefinitionList collection properly. This class, like many of the API collection classes, has the Enumerable library module mixed in. The following method should be wrapped within your plugin module: def self.get_component( filepath = "some/path/to/component.skp" ) # Warning, on MS Windows the definition paths are # returned with backslashes not forward slashes ! filepath = filepath.tr("\\",'/') dlist = Sketchup.active_model.definitions found = dlist.find {|cdef| if cdef.path.nil? false elsif cdef.path.tr("\\",'/') == filepath true else false end } return found if found if File.exist?(filepath) dlist.load(filepath) else return false end end

@oajfh said: ...Tool Observer (OnButtonUp and OnButtonDown) ... There is not a ToolObserver class in the API. The onButton.. callbacks are part of the abstract Tool class, not an observer class. @oajfh said: ... and an EntityObserver (OnEntityChange), ... Write a quick test observer and see if it fires when you move an object. @oajfh said: Does this seem like the most natural way to you ? Are there any latent bugs (seems like Observers have had problems in past versions, I can't seem to find more recent information) or potential problems to this approach (I've read up on a few common pitfalls but don't know much more) ? Welcome the foggy world of SketchUp API Dcoumentation. Where nothing is really certain, and all are kept in limbo.

hello all, i'm looking for a plugin or extension that make rotation of the object, for example any 15 degrees each, to create sprites for games or visualization. i've found web exporter beta but i'm not able to found the download link, no in extension warehouse nor plugin store. please let me some suggestions! many thanks Akira

@devinlange said: At the very least if the user modifies the faces I don't want anything to fail. This will be difficult. As faces get modified, or new edges intersect with them, they get split up into multiple faces, and sometimes get new object ids. Myself, I'd never rely on "setting" a path of primitives, and expecting the path of them to survive. Instead I'd create a virtual path. Could be a series of Guidelines (Construction lines) in a special group. Or actually maybe a Curve (which is SketchUp's name for a series of edges connected end to end,) within a group context, and on a "path" layer that can be turned off. The path and it's group can also be locked. You could associate the vertices of the path with one of the vertices of a face. Later on when you need to "follow the path" you iterate the Curve's collection of vertices, and use a PickHelper object to find the face under the current vertex. Push the face reference into an array, and repeat. Just thinking out loud.

@maricanis said: I was concerned what would happen if user select other Scene for example while tool is active, ... I believe the active_view is a singleton object of the model. (there is only one.) The user sees scene pages through the active_view.

Going back several steps .move! works like .transform! without affecting the stack within an animation ?

@oajfh said: Sorry for dragging this topic on for so long. Don't worry about it. This is the kind of nitty-gritty dirty details us consummate geeks really love to ponder.

Put the face in a group the do the followme. Everything created by the followme will be added to that group myGroup = Sketchup.active_model.entities.add_group myFace status = myFace.followme(lines) Then you can move the group.

@youngosg said: t = Geom::Transformation.scaling 2 There is an issue with this method - it doesn't produce the same transformation as Geom::Transformation.scaling(2, 2, 2) The former change the 16th value in the matrix - instead of scaling the components. I'm not sure why it was implemented as such, but several render engines have had issues with that. I think even SU have issues in some cases. Think we have an issue filed to change it.

That would do the same thing - the <form> element usually have the URL to which to submit to. Without a parent <form> the submit button had no default action.

Thanks I've missed that edge.find_faces, it works great. I think the naming put me off as I wasn't expecting that it will also add faces, I just thought it was going to find potential faces, I think it should may be renamed: find_and_add_faces just for clarity.

Thanks, sdmitch and slbaumgartner. Now It works well However, I'm planning to create some shapes more with this way and actually made few shapes. I'm worrying about increase of icons in Sketchup, and am making ideas how to simplify tools. Making dialog box I saw some free tools which 'inputbox' is added together. If the shapes can be individually selected in inputbox, I need not add icons anymore, but don't know how to make it. I know basic codes for creating inputbox, and would like to apply the basic code to what I want(choosing each shapes individually in inputbox). Additionally, Is it possible to add shapes which are saved in .skp file(I know how to load shapes saved in .skp file by using 'Class' method and how to place it on Sketchup space clicking) into inputbox too? Using webdialog If i create webdialog box and add all icons into the webdialog by making tables(categorization), This way may look good as well. I'm trying to use dlg.add_action_callback("") {|d, p|Sketchup.send_action ""} Can i utilize this command for making icons in webdialog? I mean, the command looked like only basic tools(Undo, Redo, New, Cut, PushPull) can be used with the command. For example dlg.add_action_callback("Undo") {|d, p|Sketchup.send_action "editUndo:"} dlg.add_action_callback("Redo") {|d, p|Sketchup.send_action "editRedo:"} dlg.add_action_callback("New") {|d, p|Sketchup.send_action 57600} dlg.add_action_callback("Open") {|d, p|Sketchup.send_action 57601} dlg.add_action_callback("Save") {|d, p|Sketchup.send_action 57603} As you know, these actions are used in HTML and '<scrip> </script>' connects between ruby codes and HTML codes for indicating icons in webdialog. How can I make my own Sketchup.send_action? If it is possible, I will add the icons into webdialog.
