Excellent, thanks Dan. It is working as expected, but I'm still very confused what the error was. This code works: id = "113" t = %Q^<form><input type="button" value="Click me!" id="#{id}" onclick="change_time(this.id)" /></form>^ But this one causes errors: id = "113" t = %Q^<form><input type="button" value="Click me!" onclick="change_time('#{id}')" /></form>^ As I've been playing with it over and over, it seems everytime I introduce the single quote into the function arguments, it crashes. But I'm doing it that was in other very similar onclick functions. Oh well, its beyond me. Thanks for helping everyone, I've got a wokring version now! Chris

@jrudd said: Any idea what the make_pano_pm.rb file does? @unknownuser said: Creates a set of photo matched pages given a series of panoramic images. Also creates a box (using create_box) which makes it easier to start sketching over top of the images. In the last edition of CatchUp (#5), was a article entitled: "INTERIOR DESIGN how to make a look around background" (midway thru the zine, just after "MAYOR MIKE’S GADGETS" section.) http://78.47.159.221/CatchUp_5_2011_10.pdf

@tig said: Add the Image inside a new empty group group.entities rather than the model... Manipulate the Image size etc as desired Explode the Image. You now have a face inside the group.entities Find the face in the entities - there's only one. Leave the face.material as it is [i.e. the image now made into a texture]. Make face.back_material=nil to use the 'default back material' or say use face.back_material="Black" to make it 'black'... That did it! Genius, TIG!!

Ah, thanks. Doing some tiling with thoose mesurements. Should be ok then.. @unknownuser said: The internal unit is converted to user units only in the UI That's why I got back different results in the ruby console when changing the Model precision. Maybe that goes for some other mesurement as well, havent just thought about it until now. @unknownuser said: When dealing with user units, make the Length class do the work for it. And make sure you know if your objects are Floats or Lengths. I'll try to stick to that.

@dan rathbun said: If I was a Mac only user, I'd be raisin' hell... getting a petition going, or similar to get the Mac Sketchup Ruby updated (at least equal to that of the PC.) It would be nicer if both platforms were updated to the latest patch in the 1.8.7 trunk. I am in the process of raising hell to Google... @dan rathbun said: It would be beneficial if you could figure out a way, to install an additional frameworkized v1.8.7 Ruby beneath (alongside) the Sketchup obsolete Ruby, and then have a "switching" utility that allowed the user to change the symbolic links, to load the newer Ruby. Sigh... these convoluted workarounds are getting old. I think it will be resort to using shell commands instead of the Ruby libraries I need. Mac comes with curl and gzip, and I believe this will eliminate my need for stringio as well. Thank you for your input Dan. I will pass this on to Google.

ModelTranslation[X,Y,Z]

I seem to have determined the units of the ModelTranslation values - inches. My problem now is to reset the z-axis of the model to make it easier to calculate elevations. For instance, I want to show the impact of a flood which reached a certain height. That height is given in AHD (Australian Height Datum) relative values. I presume that the location data elevations are also AHD-relative. I can represent a flood by drawing a rectangle centred on 0,0,0 and pulling the surface up to the height of the flood. The idea works well, apart from some apparent inaccuracies in the terrain data. However, it is far easier to simply pull the "water" to a given height in metres, than to convert the height to inches, subtract the Z translation in inches, then reconvert the difference to metres to calculate a level relative to 0,0,0 to pull to. Flood level

Here's a way that doesn't iterate every windows there is. It enumerates the windows of the calling thread. Cuts down the searching and ensure that you don't get the wrong window. win32_sketchup_window.rb

@chris fullmer said: Thom gave a great example with some if loops I think that let you blend the entire rainbow smoothly from red to pink to purple to blue to cyan to green to yellow then orange and back to red. I'd have to search a ways back to think where that was posted though. I couldn't find the example I posted earlier either, so here it is again: # Soft Selection Colour Map # Colours to translate to. First is max, last is bottom. @clr = [] @clr << Sketchup;;Color.new(255, 0, 0) # 100% @clr << Sketchup;;Color.new(255,255, 0) # 75% @clr << Sketchup;;Color.new( 0,255, 0) # 50% @clr << Sketchup;;Color.new( 0,255,255) # 25% @clr << Sketchup;;Color.new( 0, 0,255) # 0% def self.clr; @clr; end # Accessor # (?) Should this be done by CExt? def self.value_to_color(value = 0, max = 100, min = 0, clr = @clr) # Cap value to range. value = [min, value].max value = [max, value].min # Calculate what colours to blend between and the blending ratio. n = (value-min) / ( (max-min) / (clr.length-1.0) ) index1 = n.to_i index2 = [index1+1, clr.length-1].min ratio = n - index1 return clr[index2].blend(clr[index1], ratio) end That's the method I use in Vertex Tools to colour the soft selection: [image: KA9c_clr.png]

Yes, I understand. I've seen your praising for it. That made me want to try to learn it in addition to standard JS. Can say.. Haven't been using Jquery for long(or JS for that matter), but only the selectors themself is worth the use of it.

@adamb said: Ruby has "green threads" which is simply the Ruby interpreter locally slicing & dicing its own execution thread. But since the Ruby intepreter itself is being scheduled from the runloop of SketchUp, its of little use for asyncronous work. In other words, if I have a progress bar inside a C extension, it will suffer same 'halt' as whole SU user interface, when Ruby is doing heavy lifting, right? Does it mean that I have to start an independent thread with the progress bar to have it updated in same conditions?

Creating entities in SketchUp is slow! Very slow and it gets slower the more entities you have in the context. It also triggers all kinds of observers etc. If possible, avoid any kind of calculations without temp geometry. ( Some times you have to, like when you want to trigger SU's merge feature to make sure things heal up properly. Or if you need to get the current user axis - then you need to create two dummy groups.) And yes, using the built in methods of SU for calculations is much faster than trying to do it in Ruby. Make use of the Geom module for all it's worth. For Vertex Tools I even ported the method that calculated soft selection to a C extension because in Ruby it was slow as a sleeping snail. Any calculation, even simple 2 + 2 operations eat time in Ruby - which you notice quickly when you do it in a look. But the biggest bottleneck is adding entities in SU, and that's not much you can work around other than trying to use the bulk methods whenever possible.

That sounds good. Though, might be good to start simple, just so that it doesn't get so complex it'll never finish. (I've been there soooo many times... )

A lightweight solution for plugin installers is to use self-extracting zips: http://www.izarc.org/tutorials.html#sfx izarc gives you a few basic options as well. You'll have to make separate installers for 32/64bit Windows (since 64-bit systems use C:\Program Files (x86)).
