hi everybody, thanx for this interesting discussion, and yes, tig's way worls perfectly, so it is possible to immitate the mouse movement of single entities in any angle and direction. fantastic! new_line10 = entities31.add_line pts[1], pts[0] tr = Geom;;Transformation.rotation(pts_senkrecht1,@vector,@angle_m.degrees) group31.entities.transform_entities(tr, new_line10) #MOVE 1 FACE >>>> number distance_m_result = @carrier_w *@totaloffset_x_center/@run vector2 = new_line10.line[1] vector2.length = distance_m_result.abs tr = Geom;;Transformation.translation(vector2) group31.entities.transform_entities(tr,group31.entities[number]) stan

@bobdiya said: But given that the user is likely to rotate the cube (<90 degree off the global axis) ... Because now the default bounding boxes are larger and they don't represent the bounds of the cube themselves. Correct? True. @bobdiya said: ... then I will have to create and keep references to the bounding boxes? BUT then THOSE bounding boxes are not rotated,... their corners do not occupy the same vertices points that the cuboids do. Meaning that cubiods could have been rotate away from each other... so as not to be intersecting after rotation.

oh yes, and how it went......i am just about to begin to understand the basics. but i am proud of having the first version of my ruby nearly finished. the code is still more linear then intelligent, but will be improved step by step. and one day, who knows, i also can deal with metrices in the 5th dimension. merry x-mass stan

hi, problem solved, it was sketchy physics. i will try to redifine my code later, maybe i will find the problem. stan

Ho I didn't see that, thanks a lot!

@tt_su said: hm.. that looks like a SCF redirection error.... Redirect bug corrected. If the error message is cached, a browser cache-erase might be necessary.

Sorry, the official name is "SketchUp C API". "SLAPI" was just an acronym thrown around before I begun which has stuck with me.

hi tig, great , good formulas for further studies. my code works now, by the way. just to precise my informations: i understand, that "atan" only works for right-angled triangles (one angle = 90 degrees), but: is the sum of angles not 180 degrees in all triangles? so the criterium is the right angle, not the sum of 180 °, right ? "jumbling up radians and degrees [again]" _:) yes, i still sometimes mix it somehow, but i try to keep all calculaction in skp-origin and only to display in the console in degrees. seems to work now! _ so thanx again, all your tips makes my learning much easier! btw.: when a beta of the ruby is done and i made my tests, do you think, you and maybe somebody else , too, could check it on his machine? i have lots of rubys in my sketchup, so the compatibility here is ok, but who knows...!!! thanx stan

group2 = group.copy group2 = group.move!(vector) group2 = group.copy group2.move!(vector) Should leave group where it was ???

Functionally, there is no difference. BUT.. technically, Kernel::puts(), is a COPY of the instance edition of puts() that got mixed into Object, and will get inherited by ALL other classes and modules. The Ruby Core Team wrote the Kernel module as both a Mixin and a Library module. They used the module_function() method, so that all the library instance methods (that get mixin in using include,) had module method copies made. These copies can only be called by qualifying them with the Kernel module name. [ruby:1c8jtequ]Kernel.module_eval "class<<self; method(:puts).inspect; end;" >> #<Method: Class(Kernel)#puts> Kernel.module_eval "method(:puts).inspect;" %(#000000)[>> #<Method: Kernel.puts>]

Thank you, Thomas!

I stumbled onto this download at Microsoft (looking for something else.) Microsoft SQL Server ODBC Driver 1.0 for Linux The Details say it's for 64bit RedHat 5/6. (But maybe if your Linux uses the same Core..)

Two posts above you Tig has given you the link.

@tt_su said: These snippets should work: http://sketchucation.com/forums/viewtopic.php?f=180%26amp;t=41211#p365380 Oh, cool! Thanks a lot!

hi dan, that's exactly, what i ment. i want to restore the user file path after my ruby finished it's job. perfect! thank you very much, also for the other system variables, very useful for future development. stan

entities.fill_from_mesh(mesh, true, 2 | 8) is working nicelly, but a small gotcha.. %(#FF0000)[mesh.add_polygon(1,2,3) mesh.add_polygon(2,3,4)] Does gives hard edges, as expected. %(#FF0000)[mesh.add_polygon(1,-2,3) mesh.add_polygon(-2,3,4)] gives hard soft edge between Points 2, as expected. but so does this: %(#FF0000)[mesh.add_polygon(1,2,3) mesh.add_polygon(-2,3,4)] or %(#FF0000)[mesh.add_polygon(1,-2,3) mesh.add_polygon(2,3,4)] So I'm starting to see some trouble with this method. To be able to stear edge visibility one need to use 2 Points in comparison. For ex a Collection of edge.start and end positions. For a triangulated quad this works but not if the face has innerloops, Or faces where triangulation is splitting the face without hitting innerloops. Was to fast here.. The docs actually explains this behavior, "value of [-1, 2, 3] indicates that the edge from 1 to 2 is hidden"

hi tig, ok, let's play with some formulas thanx stan

hi dan, thanx, next step is done! this one works: @c_step = Sketchup;;Color.new(30,125,180) group.entities.grep(Sketchup;;Face).each{|f| f.material=@c_step} stan

Thank you, Dan, it works OK now!
