sorry, I must be really tired today. I meant you can't use a pickhelper outside of the current context. so If you you have two instances in the model, and you double click one, you can't use the pickhelper on it's sibling.

What difference between file exported to format Collada and files exported by script SU2KT ?

@unknownuser said: [Is it because ] super [is ] a keyword? Hence this exception? I believe so. If you look at the lex.c file in the Ruby source, you'll see there are only 3 keywords that use argument lists: defined?, super and yield. In the eval.c file, you see these statements are converted into internal C function calls, (like everything else in Ruby.)

Tig, true, normally i always check if the array has any value or length>0 What would be the best way to check if an array has values? I assume length is the way to go? test=[] if test==[] -->TRUE if test==nil --> FALSE if test.length<1 -->TRUE

Great, not sticky?

Great thx Tig for the extra explanation Now if only this was possible for materials to (without having to duplicate the entities first) BTW Tig, do you know if is possible to refresh the Layer window?

@cjthompson said: Has anyone figured out how to use threads fluidly, so that ruby and regular sketchup will work at the same time? All attempts to use threads I've heard about had failed. Apparently it is a no-go.

@thomthom said: I got the impression that the name was not the issue, but the path. Right. loading a definition with the same path returns the in-model definition with the same path, and does not re-load it from disk. The name is not important, but it is the path that matters. If I save_as the definition to a new path, then load will work on the original path, and the new definition's name will be incremented. I wanted to avoid saving the old definition to a disk file and all the mess that goes along with that - such as finding/creating a folder to save it to and cleaning it up afterward. What I found is I can cdef.save_as("/dev/null") which will reset the path, but not actually create a file on disk. Then I am free to load the definition again - a re-load, although the definition name is incremented. This apparently works on Windows as well as Mac even though Windows does not have a /dev/null file. Perhaps Ruby just knows how to deal with it. Can anyone confirm this does not create a file on disk on either Windows or Mac?

but what is the good guy?

@tig said: You could also ensure that the SUp import units [set under options] matches the original DWG's units - otherwise it can become too small anyway... YES!!! it works too. Thanks.

how about draw your own plane and use intersect selected?

something like this: def pointBetween(a,b,c) array = [[a.x.to_f,b.x.to_f],[a.y.to_f,b.y.to_f],[a.z.to_f,b.z.to_f]] x = c.x.to_f.between?(*array[0].sort) y = c.y.to_f.between?(*array[1].sort) z = c.z.to_f.between?(*array[2].sort) return x && y && z end I'm not saying it will work, I'm just wondering whether it will or not.

Polymetronic seems like it would require batteries.

OK great. Come back with questions as often as needed. Chris

I've used Tkinter with Python. It gives excellent results in about half the code wx requires. It's set of widgets isn't as extensive as wx, but it's much better than JavaScript's tiny set.

@kat said: I don't get the tangent = (normal * binormal) multiplication. Isn't B supposed to be the cross product of N and T? Makes no odds. Binormal and tangent both lie in the plane. @kat said: And why is gives @adamb said: (xform * binormal).length * (xform * tangent).length you the scale factor? I'm taking the unit vectors in the plane of the face and transforming them by the Group transform which may scale them. Getting the length in the binormal and tangent direction allows me to figure out how much to scale the area of the face accounting for the transform. Adam

why don't we just start discussing Lua while we're at it? no, but seriously Python is just a different language. I learned to use it before ruby, but then I discovered ruby, which I prefer for many reasons other than it's speed, which as mentioned is slow. Yes compulsory indentation is nice in some respects, but it is a complete and utter pain when mixing tabs with spaces (can't see where the problem is). Ruby allows for more creative formatting of the code (which can be very nice). I like them both, and don't we all wish the best of both could be combined?

Just for the record. I found this: http://www.rubyonrailsftw.com/lessons/28, after posting. @unknownuser said: If you get this error, you need to install 2 openSSL .dlls: Get openssl Download openssl windows binary from http://gnuwin32.sourceforge.net/packages/openssl.htm Unzip “libeay32.dll” to ruby\bin. Unzip “libssl32.dll” to ruby\bin and rename it to ssleay32.dll In some systems, you need to put those dlls by force on windows/system32, or on ruby/bin, if you are not running SU's ruby interpreter.
