Hello everyone I reference everyone's suggestion The successful implementation of the following code: mod = Sketchup.active_model ent = mod.entities grp = ent.grep(Sketchup::ComponentInstance) for i in 0...grp.length - 1 grp.each{ |g| next if g == grp[i] bb = Geom::BoundingBox.new.add(g.bounds.intersect(grp[i].bounds)) if bb.valid? puts "#{g.name.to_s} and #{grp[i].name.to_s} intersect" else puts "#{g.name.to_s} and #{grp[i].name.to_s} do not intersect" end bb.clear } end Next, I want to know how to calculate the model of dynamic properties of all objects (such as "Lenx", "Leny" ,"Lenz"...etc) after the object intersected the other object. The case description like this: First, detect all objects intersect situations like the above code Second, if name = "column" objects intersect name = "beam" objects(just a simple example) then, "column" objects dynamic properties("Lenx") deduction "beam" objects dynamic properties("Leny") Thank you for your advice and help [image: NS2n_01.JPG] [image: ZMDk_02.JPG]

Thanks for everybody help and advice The problem has been resolved

Thank you very much, it's works fine.

One was written back in 2008 named Event Relay. It received little attention and the author last visited SketchUcation in 2009. The code for is hosted here: https://code.google.com/p/eventrelay/wiki/EventRelay Maybe the code could be updated. If this were my goal and I was using Windows, I would try to create an Autohotkey script.

@bomastudio said: Hi Guys, I have an agony-problem with a 3D rotation. The transform that TIG suggested (rotation) works for your need. The docs on transformations aren’t very clear, especially for people who aren’t familiar with 3D transforms or linear algebra. They’re also a little quirky, as the trans.to_a method returns a matrix that is the transpose of what I would expect. FWIW, I had a lot of linear algebra (long time ago)... Anyway, the rotation method returns a transformation based on a rotation in a plane, which is defined by the ‘axis’ parameter, which should be the normal to the plane of rotation. If the start and end vectors are parallel, they do not define a unique plane, hence, both my original ‘linear algebra’ algorithm and the rotation method fail. The code below accounts for that – Greg module SUMath def self.transVector2Vector(vStart, vEnd, pt = nil) ptRot = pt || [0,0,0] if vStart.samedirection?(vEnd) # return identity transformation, vectors are in the same direction Geom;;Transformation.new elsif vStart.parallel?(vEnd) #return 180 transformation, vStart and vEnd in opposite direction Geom;;Transformation.axes(ptRot, [-1,0,0], [0,-1,0], [0,0,-1] ) else # return rotation transform based on vStart and vEnd # vCross is normal to plane of rotation vCross = vStart.cross(vEnd) ang = vStart.angle_between(vEnd) Geom;;Transformation.rotation(ptRot, vCross, ang) end end def self.rotateFace(face, vector_end, pt = nil) # for demo purposes, the next 2 statements chose an arbitrary face # if no face passed unless face entities = Sketchup.active_model.entities faces = entities.grep(Sketchup;;Face) face = faces[0] end face_normal = face.normal t = transVector2Vector(face_normal, vector_end, pt) entities.transform_entities(t, face) # below is just for a demo confirmation sd = face.normal.samedirection?(vector_end) sVEnd = "[#{vector_end.join(",")}]" puts "face.normal.samedirection?(#{sVEnd}) = #{sd}" end end # load module thru console # type SUMath.rotateFace(nil, [0,0,1]) into console with whatever vector # you want, it can be typed as often as you'd like. # As a demo, best done with one face in the model

One can also wrap Dan's code in a method def self.operation(opName, procElse = nil, procEnsure = nil) if (block_given? && String === opName) am = Sketchup.active_model begin am.start_operation(opName, true) yield am.commit_operation rescue => e am.abort_operation puts("Error operation block #<#{e.class.name};#{e.message}.>") puts(e.backtrace) if $VERBOSE else procElse.call() if (Proc === procElse) ensure procEnsure.call() if (Proc === procEnsure) end else raise "Error operation parameters - No block given or opName not a String!" end end # call by # operation("My operation") { operation block } Note that if either procElse and procEnsure are used, they should probably be lambdas. One should also be careful about return statements in the block passed to the method. BTW, I'll use snake case for methods, maybe not variables... Greg

I would use something like steve suggests... %x(defaults read ~/Library/Preferences/com.sketchup.SketchUp.20#{Sketchup.version.to_i} "SketchUp.DefaultFolder.Models") BUT, it always returns the last Folder used for a Save...

Anton, Thanks. It's a pity that there is no built-in mechanism (such as the return value of the callback defined in set_on_close). We can also understand that SU wants to preserve a way to close the web dialog 'whatever' in case of trouble. Anyway, reloading the HTML works fine. I just noticed that redoing just a show() create this delay in capturing mouse events. Fredo

@unearthed said: I haven't tried this yet as I'm on the road but have been hoping poisson distribution would get scripted for SU. A while ago ago I posted this query http://sketchucation.com/forums/viewtopic.php?f=323%26amp;t=55779%26amp;hilit=+poisson . Did not see your post, distributing plants is certainly something I also thought of before! Not sure about Poisson Sampling with ruby, was thinking going the other way - a more performant solution using OpenCL or CUDA - because sampling is quite numerically intensive. @unearthed said: Currently when I want these (for 'random' planting layouts) I run them in R and export to dxf - Your method offers possibility of saving two steps and keeping everything 'in house'. One extra though - would you be able to add a ratio for each different component so as to get an effect as in the link's first image? Right, the percentage of the total samples for each component? I could certainly do this, perhaps I will make an update this weekend if there is time. As with regards to using different radii (for each sample/plant to have a different minimum radius), as also mentioned in your other post - I will see how quickly it can be done, perhaps if it takes more than a few hours (if done efficiently!) I'll think of releasing a commercial plugin. Greetings

@al hart said: I "fixed" it be downloading the 3D Warehouse models, turning off the ground plane, setting the background color to white, and then re-uploading them. Well, you never said they were YOUR models. Of course you are responsible, if you left the ground plane turned on. LOL

It turns out the the other developer had defined a override to Length which returned a value of class Area when 2 lengths were multiplied. We were multiplying the bounding box extrema to try to calculate an approximate volume if volume was not defined. if (entity.respond_to?(:volume)) rval = entity.volume else rval = bwidth * bdepth * bheight end#if They plan to fix it, but I think I can coerce each "length" to a float before multiplying them: if (entity.respond_to?(:volume)) rval = entity.volume else rval = bwidth.to_f * bdepthto_f * bheightto_f end#if Actually I will do this earlier when I get width from the bounding box

To set up a shortcut that is context-sensitive you must be in that selection-context. So to shortcut 'Edit Group' you first need to select a group to get that possibility in the context-menu and you must then open SketchUp's Preferences > Shortcuts and filter for 'Group'... - then set up the shortcut on that tool's command... then of course you'll need to mimic some key-presses etc in some third party code executed by Ruby - all as outlined earlier [PC only]... PS: This 'context' issue when making shortcuts applies to many selection-sensitive commands - like Reverse and Orient, which both need a face to be selected before they appear in the context-menu list...

Assuming you wrap all of your code in a method inside your own module... @x = 1.m unless @x @y = 1.m unless @y @z = 0.m unless @z results = inputbox(['X: ', 'Y: ', 'Z: '], [@x, @y, @z], 'Slicing Rectangle Dims') return nil unless results @x, @y, @z = results BUT then you need to decide the values for each point... If all of the slices are in plan then only the Z value is important. Can I suggest you use: bb = model.bounds min = bb.min max = bb.max then a single input for the Z thus: @z = 0.m unless @z results = inputbox(['Z: '], [@z], 'Slicing Height') return nil unless results @z = results[0] Extract the x/y/z values from min and max and make the points for the face from those... p1 = [min.x, min.y, @z] p2 = [max.x, min.y, @z] p3 = [max.x, max.y, @z] p4 = [min.x, max.y, @z] later entities_b.add_face(p1, p2, p3, p4) Note how whe adding a face you only need the points for each vertex, if you were adding edges you need to add the extra 'p5' to close the loop.

Thank you for giving me advices. The problem has been partly fixed by myself. Maybe, I have to pay attention to studying ruby more

yes ! ok with touchmousepointer ! thanks

You do not need sorted = [], as grep makes a new array, then sort makes another new array. Save yourself some grief. Use puts or pp output to the console, rather than UI.messagebox, for testing. ( UI.messagebox can fail silently if the C WinAPI functions do not like the string passed to them.)

@dubai_skyscraper said: The initialization in line 930 + 931 looks like this: def_screw_thread = def_list.add ("Screw thread") ent_screw_thread = def_screw_thread.entities I really thought that looked like a space, between the .add and the ("Screw thread"),... It could be a "vacuum" character though. P.S.are brackets, { } are braces, ( ) are parenthesis.

Thanks for the help I just got to part of the program where this is needed. I visulized 6 to10 lines of code knowing that unique would work directly. Keith

I am an avid sketchup promoter and user and have follow and use many extensions created by the authors from this thread i am very interested in being able to export all scenes to layout, does anyone know how you can import all the scenes from your sketchup model into individual viewports in layout, i usually have to create over 50 individual pages and individually select each scene for each viewport, is there any way to do this automatically I would be very grateful to pick your brains let me know if you have anyway of accomplishing this, writing a macro, or anything Please let me know any thoughts you might have cheers!
