Mike I was thinking the same thing about his tutorials and voice.

Awesome! Thanks everyone. For now I will finally get a chance to play around with Layout and then use that as the selling tool once the 8 free hours of the pro tools. In Wisconsin in middle and high school that is generally used by students to make one more 3d version of Lambeau Field though I presume in Manchester UK, Paris FR or Denver CO it might be a different stadium.

Sorry for being unclear. In general you can't copy joints and you probably shouldn't even rename them. Many joints can however, share the same value for things like thrust. You can use a slider for instance, so they act in unison. a "$" in front of a variable name makes it global so it can be essentially called from all of your joints. I'll try and make a little video and post it to do a better job of explaining it. Hang in there, once you get past a few quirks sketchy physics combined with a little ruby scripting is loads of fun.

As school starts up again here (at least in the US) I am busily advocating for more creative use of sketch-up and sketchy physics at our local high school. After much prompting the district has installed 2000 laptops with the "make version" 2013 and I am wondering if it is worth the fight to promote sketchy physics' (warts and all) installation. Has anyone done any comparison testing for sketchy physics running on Sketchup 8 and Sketchup 2013? I haven't given up the discussion to get them to take advantage of Trimble's generous K12 partnership program for Pro but I need to pick my discussions carefully.

Joint names I think need to be unique but you can give them a common controller name or (and I know it is bad practice sorry TT) a common global $variable.

What you describe should have been possible especially if you had a gyro attached. You are probably trying to avoid this but functions from the sketchy physics library like teleport or setVelocity would probably work.

We can try. http://camstudio.org/ is one place you can get a screen sucker. If that doesn't work check back and we can see what we can do.

Anything that gets folk using git is a good thing. That cool sketch-up community empowered with the power of github would be incredible

Sounds like a good idea, especially the github part, but are there other efforts out there?

Any tips for going the SQLite route?

Awesome. Thanks Rich!

Exciting to see. Looking forward to putting it to good creative use.

This is a small model built with some code to make it usable for sketchy physics (and perhaps 3d printing). Does anyone know how this would print on a makerbot?

or by just modeling with some pretty bizarre music

This will give you a construction line defined by a point and a vector. If you want to draw a line segment aka edge you could get the second end point by applying a scaled transformation to your initial point.

It takes a village to perfect a render. Love it!

Anton: hooray for you. Can you give a quick rundown on what you have or will be doing? I will also try to experiment with what you released above but a short rundown would be greatly appreciated.

You are a good man Chris. ....as Rosanne Rosana Dana once so eloquently said.....never mind.

I will piggyback on this post to ask a related question both of which will be solved with linear algebra I am sure. How can you take a group's transformation and determine which way it is pointing (the components of its internal positive x) and its up (the components of its internal z)? I think this is just a middle step to the above problem where one calclulates the "basis vectors" of the bounding box by taking differences of coordinates of the corners and then normalizes them.

Probably bad form here to answer my own subquery but what the hey. The following code snippet demonstrates that for a particular component instance of an unscaled component or group, the basis vectors (component x, component y and component z) are just the [0-2], [4-6], and [8-10] positions of the component transformation. In my own particular case I am trying to add lift, drag and thrust values to objects in sketchyphysics based on the attitude of the object.

` model = Sketchup.active_model
entities = model.entities
selection = model.selection
#this assumes only one entity in the drawing
#which would be a group or component
#the basis vectors for the component definition
#are calculated into xvdc,yvec and zvec
#and then drawn at the origin
t=entities[0].transformation.to_a
orig=[0,0,0]
xvec=[]
yvec=[]
zvec=[]
for i in 0..2 do
xvec.push(t[i])
yvec.push(t[i+4])
zvec.push(t[i+8])

end
puts xvec
puts yvec
puts zvec
entities.add_line(orig,xvec)
entities.add_line(orig,yvec)
entities.add_line(orig,zvec)`
