aoh, I need to have that file Win32API.so in the plugin map! thanks

@garry k said: This is NOT as expected - regardless. I know myself that I work mostly in millimeters but feel quite at home going back and forth. All the other built in conversions work just fine. Just not this one. Yes I think it IS a bug. Today I tested with a model set to decimal feet (0.001) and got this: ` '2 1/2"'.to_l 30.0 Sketchup::format_length('2 1/2"'.to_l) 2.500'` So the inch symbol is ignored. But in a model set to inches: "2.54'".to_l %(#008000)[30.48] So it seems the foot symbol works, IF the numeric is decimal. But IF it is fractional (model set to inches): "2 1/2'".to_l %(#008000)[24.0] **So I agree. It is a bug issue with fractional expressions. ADD: The error also occurs within the VCB (Measurements Box) !**

thanks!

@fredo6 said: The Selection observers remain completely silent about the erasing of the current selection. No event is fired. Not true... they are calling misspelled callbacks. To see what the SkecthUp engine wants to call (even tho the spelling is a bug,) ... override the respond_to?() method in your observer subclass, (being sure to pass the arg on to super,) but puts'ing the method name to STDOUT. Once you know the mispelling... you can write wrapper callbacks that use the mispelled method name that simply call the correctly spelled callback (or just alias the bad names to the good names.)

ok, thanks

Last I knew Mac only worked with string arguments for actions.

Short and ride to the point Thanks again Dan! Have a nice new year's eve...

(1) If you are going to develop, logon as an admmistrator, so you have full access rights to the plugins folder. (Or right-click the SketchUP icon, and choose "Run As Administrator", or "Run with elevated Privileges" etc.) (2) Forget about zip & rbz during development, that is the avenue of distribution. (3) Stop thinking of SCRIPT, and start thinking of your code as being defined WITHIN and executing FROM your namespaces. You need to choose a toplevel namespace (module name,) and then write ALL of your plugins within a sub-module of your toplevel module. (Clarify: I mean each plugin has it's OWN sub-module of your toplevel author/company module. That way NONE of your plugins clash with each other, NOR any other author's plugins.) (4) BE wary of comparing Ruby to Fortran, BASIC, etc. Ruby is MUCH different. It is a dynamic language. This means that modules and classes can be modified at any time. Methods can be redefined, removed, access changed (made private,) etc. This also means you can reload a file that defines your plugin's module, after making changes, and the changed methods are updated. This is great for development. (5) Ruby is 100% object-oriented. Ruby has 2 (TWO) things. Objects and references that point at objects. Ruby does not really have variables, but the documentation and some query methods refer to "variables", but I think it is best to have programmers from other languages know from day one, that Ruby only has references, not variables like BASIC. For example, Ruby references can point at any object, at any time, of any class, and then be changed (re-assigned,) to point at any other object, of any other class (or perhaps the same class.) So any "typing" of reference names is only in your mind. It it makes you "comfy" to say use bMyRefName to hold a reference only to true or false (or nil,) then thats OK. Add (6) Read the "Pick-Axe" Ruby book cover to cover. (see the Ruby Resources sticky topic.) Doing so will make your journey so much easier, and avoid asking all the questions here that people who do not read the book first have already asked (here and in other forums.) (7) Do not think or write your code in a linear manner. Think in and write code in an event-driven manner. (Have your code respond to things the user does, or act upon objects the user has selected, or do something with the entity the user has just modified, etc.) See the API dictionary on all the observer classes.

Thank you for your help! Turns out the camera that the photos were taken off of had some weird GPS offset, which is why my photos were imported yet placed kilometers away. I solved my problem by using a 'reference point'. I have the user import one photo and place that photo where they believe it was taken. I use that photo's lat and long to modify the rest of the photos that were imported. Success

There are several 'rectangle' plugins available, like '3 point rectangle' ... My own 2Dtools includes a 'rectangle tool' making 4 edges - no face... The principal is very similar to the line-tool example, instead of picking 2 points, you pick 3. The 'box' tool also has a potential crib... Point 1 click = p1 the start of an edge Point 2 click = p2 the end of that edge A Vector - vec = p1.vector_to(p2) Point 3 click - poff - this defines the offset to the opposite side NOT a vertex. A Line - line = [poff, vec] Project p1 & p2 to line p3 = p2.project_to_line(line) p4 = p1.project_to_line(line) Now if you want a face: face = Sketchup.active_model.active_entities.add_face(p1, p2, p3, p4) The edges get automatically added. If you want just edges: edges = Sketchup.active_model.active_entities.add_edges(p1, p2, p3, p4, p1) Remember to close the loop by reusing the first point again at the end... ***To get the temporary graphics rubber-banding that is needed in 'draw'... use the initial 2 points as if it's the line-tool, and then after the stare increments... while waiting for the 'poff' click the mouse's cursor-position can be used for calculating the the dynamically changing projected points from those 2, to draw the four sides of the potential rectangle as the cursor moves...

Well it is replaced with Win32API.rb which is a wrapper that uses the DL library. So you can still use it. In later versions even DL is deprecated and becomes a wrapper into the Fiddle library. They (the Ruby Core people,) want coders to begin using the newer libs. But not every user installs the full Ruby libraries. It is easier to just use the Win32API class, for now.

hi tig, yes, i understand the principles of giving attributes to entities now and will try to experiment with this. maybe i may go step back to my special situation (just for understanding): i have an axis of different edges, giving a path for 'followme' , then i let create the ruby the same object again and again (imagine: square, path, followme, delete square, path, followme, delete etc.) the funny thing is, that the entities DO have a numbering , which is their position in the array, right? and so a thought, while knowing , which entity has which number in the row, i could access them easily (again: always the same object with same amount of edges and faces from the same procedure) but at this point the numbering of faces in the array changes, although generated thru same procedure. and since the object is a follow-me- object, i cannot give any attributes to single faces, i guess..... so that's the trouble. but i can gerate these objects per hand too (face by face), so i will be able to use the 'attribute' option. regards stan

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
