See you at Lisbon

Please stop calling them 'lines' - I know that's the CAD name but in SketchUp Ruby code they are best called 'edges' - I know some SketchUp tools refer to drawing 'lines' and there's even an API method add_line() that adds an edge BUT when we are talking code - especially if we are taking about edge.line - it's a recipe for confusion to muddle up the two terms... I tried to explain the difference between an edge and a line [edge.line]... The two perpendicular edges you drew will only return a point with the intersect_line_line() IF they intersect - i.e. they are 'coplanar'... looking down 'in plan' does not mean they do intersect if their 'z' values not equal... Assuming they do return a point, then my previous post explains how you can then tell if that point falls 'in space', or either of the edges' vertices, or on an edge in between its start/end... It'd be quite possible to slide your example edges around so that they then return a point 'in space' that is on neither edge...

Hi Dan, Thanks a lot for the reply! Having the Java program write to a file and then having the Sketchup script read it in is a good idea. I'm going to try that. Can I use the 'File' object to accomplish this in a Sketchup script? Having said that, for me latency is an issue, and I don't know if the time for writing and reading from the disk will slow me down - but I guess I'll only know after I try. Actually what I am trying to accomplish is have a controller control the camera in the Sketchup model. The controller has APIs in a bunch of languages (Java, C++, Javascript), but none in Ruby. There is one interface created by a third party that uses SWIG to wrap the C++ functions and make it accessible in Ruby, but those are 'listeners', and I don't know if they would work within Sketchup Ruby. Do you know if it is possible to have the a .rb script, run via the Sketchup Bridge from within an IDE, that acts as a listener? (Sorry if this is a bit vague - I'm don't have much experience integrating a scripting language like Ruby with something like Java or C++. Let me know if I can clarify this further).

Didn't try. Then you'd have to hook into the windows messages. yuck

Hi , The process : Store Data - Components , Patterns , Panels of original data from Architect's Model Tag Part Number - Select Panels ,and distinguish different panels type Auto Open Patterns - To recheck the original design Re-Tag Part Number - The users have to change after checking Patterns , Different patterns have different tag numbers even though they are the same sizes. My expectation needs to " Store Data and Recheck Patterns later for a RE-TAG Number correctly " as a facade designer wants.

@chris fullmer said: ... suspend will tell you if the user has started using orbit or pan, ... Really? That is news to me. (The API docs do not say this.) AFAIK, a tool's suspend callback is called JUST BEFORE the tool becomes inactive, (so you can save stuff like your tool's state etc.,) and BEFORE the interruptor tool becomes active. Also.. because the Sketchup::Tools collection does not have Enumerable mixed in (and an each method defined,) there is no way to non-destructively read the last tool on the stack, nor even iterate the stack.

Try point = Geom.intersect_line_line(edge1.line, edge2.line) You either get a point or nil if the two 'lines' don't intersect. Unlike an 'edge', a 'line' is infinite, so two 'edges' might not physically intersect even though their 'lines' do. If you get a point you can then test if it actually falls on an end point of an edge point == edge1.start.position point == edge2.end.position point == edge1.start.position point == edge2.end.position where true shows it is at a vertex AND if the point falls between the start/end of each edge, the test is... point.vector_to(edge1.start.position) == point.vector_to(edge1.end.position) point.vector_to(edge2.start.position) == point.vector_to(edge2.end.position) Note that getting true means that the point is not physically on the edge because the vectors are both in the same direction, and false means that the point is on the edge and between the start/end...

Thanks Dan ! , I never realized about this method. My supervisor wants me to switch schemes for " DESIGN COMPARE " at the same position to open and hide layers , then show all schemes by coding. The layers now are overlapped.If I can't do at the end I will do only Switch One by One. http://www.youtube.com/watch?v=ZffmxlB5dbk&feature=youtu.be

I respect you !!! I'm a big fan of you.

@tt_su said: That will prevent the initial white dialog under OSX. Yes I did that and received feedback from a Mac user that the dialog was loading ok. @tt_su said: On a sidenote, I always recommend jQuery or similar frameworks. They take care of most cross compatibility issues - even in this case because jQuery.ready() event uses the DOM ready event which doesn't cause any white out. I will need to study how to implement this for future...thanks!

Too many recursion levels can be a problem (with memory I think.) We have discussed this in other threads. Do a forum search on "recursion".

@tig said: Read my SmartOffset code to see how I offset the edges of a given face... That is by no means an easy task but I will try to understand what you wrote. Isn't there a 1st grader version? @tt_su said: Side note - Ruby is very slow. You'll find using the SketchUp API's .distance method much faster than doing your own length calculation. At least if you do this for a somewhat large set of entities. That is good to know thanks!

No it's was not ! But now seems you have made something , because seems that works! Bravo for that! Maybe these particular advertisements enter in conflict ? PS In any case : the second line of links at the bottom page seems a good idea! (and not a big effort of programming!

JSONPadding Will try that. Thanks a lot!

@tig said: SO THEN **b = a.split('')[4..-1].join('')** o there should do it, even with strings containing non-ASCII characters Great advice!...thank you guys!

Thanks, Dan! Your idea worked out very well using "onTransactionCommit" event of the Model Observer. On every commit event I simply reset the "changed" flag and then do the rest as you proposed.

Great, thanks !

Sorry to drudge up old news, but this is an embarrassingly old issue, be nice to have a filter option in the API by now. Here was my solution because I didn't like the fact that it could possibly overwrite a file accidentally using TIGs approach (untitled != untitled.txt for example). Anyhow it can be a burden to hit save twice, but I'd rather do that 100x then accidentally save over something important. Where: EXT = "txt" default_dir = "c;\\temp\\" default_file = "untitled" The following while loop: name_valid = false while name_valid == false path_to_save_to = UI.savepanel("Save Code File", default_dir, default_file) #path_to_save_to = path_to_save_to.tr("\\","/") # This maybe required. fileext = File.extname(path_to_save_to) # filename with prefix stripped filebase = File.basename(path_to_save_to, ".#{EXT}") #puts fileext.inspect if fileext == "" || fileext == nil default_file = filebase + ".#{EXT}" UI.messagebox "Oops! Including the file extension '#{EXT}'\nThis is an embarrassing workaround...\nPlease hit save again." #puts default_file.inspect else filename = filebase + ".#{EXT}" path_to_save_to = File.dirname(path_to_save_to) + "\\" + filename name_valid = true end end

@mitcorb oslocadiz is correct, the script is not at a point where it's useful in any way. I'm just in the first stages of learning Ruby, so this post was more as a way of asking the skilled developers in the forum for advice and feedback, not as a usable script at this point. Furthermore, TIG's produced (as usual) a very capable script that does Datum measurements, I'd recommend that. I may shelf this project for the time being anyway, as it's a little to ambitious for my knowledge at the moment. I wish I knew more, but I just haven't had the time to devote to it enough, or enough understanding at this point. Thanks for the interest, Matt
