What defines a good or bad pairing?

No overlap when moved center to center. Where 'center' is center of paired face.

No worries - we all learn. Thanks for posting back your solution.

how about closest pair of points?

Since you are only dealing with two objects, it shouldn't matter which is sel[0] or sel[1]

To find the closest corners of two objects

mod = Sketchup.active_model > . > . > . > UI.messagebox "Obj0 Cor#{m} to Obj1 Cor#{n} is #{Sketchup.format_length(md)}" >

Thank you for the snippet!

You are correct excepting that the tool in question will move one of the two objects such that the opposing face centers are touching plus or minus an offset. Sorry for the grossly incomplete spec 😞 My plan (very fluid and quite murky ) is take the first selection as the moving object and the second as the fixed object. I've some notion about non-parallel faces requiring ( optionally ) an rotational adjustment. However it's my goal to keep things as simple as possible. My usage is to stack components together to assemble the model much like one would in actuality. Hex nuts, lock washer on threaded rod etc.

Additionally, there is the self-educational aspect of solving the which selection is on first 😄 This tool already has four options and looks to acquire one or more in the future. So it seems prudent to solve this now to make ready for the unforeseen. 'Sides any excuse to cut code!!

My thanks...and off to read the fine manual (err...what manual?) again 😉 😉

I've read through same and I plan to do so again more thoroughly again after I get this next layer of magic nailed down. I think I now understand the two file format well enough to give it a spin in a bit but am momentarily busy prepping prototype parts for shapeways. Its been tool, prototype, tool, proto in a kind of recursive spiral! Need one for the other and round about we go...

I've been coding all the way back to my assembler days (pre 1980). Various flavors of (Basic, Cobol, C, C++, Pascal, C#, Java), many database scripting languages such as (dBase, MSAcces, Paradox), other scripting languages such as javascript, jquery, PHP, Ruby, CSS, SQL. AWK, TCL ...

I usually go with the flow. Borland built a very good library called the VCL (Visual Components Library), which makes use of an absolutely excellent object oriented set of classes. Easy to follow and very consistent stylisticly. This library is used by Delphi (object oriented pascal) and by C++ Builder.

Microsoft built a terrible interface called MFC (Microsoft Foundation Classes). So when I had to use Microsoft for various early mobile devices I skipped it and used the Win API.

With Sketchup I use a mix of both Classes (for tools) and simple reusable methods for helper functions. Even though I prefer using pointers with C, C++ etc. it just isn't possible with ruby (although under the hood most everything is passed as a reference).

Having said all that - Ruby is quite good - although there are a few too many ways to do anything. This just means it is often a bit slower reading other code as the programmer often chooses a different way to do things.

So I'm a bit more formal and like to use terse syntax where possible. ! instead of not, || instead of or, immediate if = ? :, parenthesis for all methods, lots of white space etc. For me it is all about readability so I can come back and speed read code I wrote months or years ago.

But I do like some of Ruby's ways. "#{var}" the use of if after an assignment etc.

I use a modified template that Dan Rathburn created. I also use his file naming convention for the loader etc.

You could strip this down. But I like to place my plugins in a shared folder so I can test a single plugin on 6 versions of Sketchup SU7 through SU2016
