I'm trying to inference lock along a random vector. I wrote this and it works as long as @vector is along the red/green or blue axis but it doesn't lock in any other situation. Does anyone has a solution?

@picked_first_ip.copy(@mouse_ip)
@mouse_ip = Sketchup;;InputPoint.new(@picked_first_ip.position.offset(@vector))
view.lock_inference(@picked_first_ip,@mouse_ip)

I got it working. I used the ruby-c-extension-example to create a visual studio 2017 project and compiled it. You can find the VS2017 project in the link and compile it or use the so in releases if you have Sketchup 2017 x64.

I'm trying to use the rbclipper library in sketchup 2017 pro x64 using this tutorial:
http://dagrende.blogspot.be/2011/08/install-rbclipper-in-sketchup-8.html

But instead of ruby 1.8.7 I used 2.2.4 and instead of DevKit-tdm-32-4.5.2-20110712-1620-sfx.exe I used DevKit-mingw64-64-4.7.2-20130224-1432-sfx.exe

When I try running it in Sketchup I get this error

require 'clipper'
Error; #<LoadError; 126; The specified module could not be found.   - C;/Users/maarten/AppData/Roaming/SketchUp/SketchUp 2017/SketchUp/Plugins/clipper.so>

C;/Program Files/SketchUp/SketchUp 2017/Tools/RubyStdLib/rubygems/core_ext/kernel_require.rb;54;in `require'
<main>;in `<main>'
SketchUp;1;in `eval'

What am I doing wrong?

My code gives a Cannot convert "100.00mm" to length error on some computers but not on other computers. How is this possible?

I thought the problem was that some computers use a , instead of a . to indicate a decimal mark but changing the language input on those computers doesn't solve the problem.

Thanks that works

It doesn't work in windows 10
I get this error:

Does it work inside sketchup?

Is it possible to get the mac address in ruby?
I've tried this gem: https://rubygems.org/gems/macaddr but I can't get it working.

I've also tried executing shell commands from within ruby with backticks getmac and %x(getmac) but I don't get a response.

Thanks that did the trick. Is there a reason why the face isn't removed by the pushpull command?

# create cube
subelement.entities.add_face(pointscube).pushpull(height)
# create face on side of cube
face = subelement.entities.add_face(retourpoints)
fbounds = face.bounds
face.pushpull(isolatie + binnenschil)
subelement.entities.each do |ent|
  if ent.is_a?(Sketchup;;Face)
	ebounds = ent.bounds
	if ebounds.max == fbounds.max and ebounds.min == fbounds.min
	  ent.erase!
	  break
	end
  end
end

Sorry for my explanation but english isn't my first language.
I first create a plane inside a group and pushpull it. This is the slab in the picture.
Then I create a face inside the same group. But when I pushpull this one it creates a new cube touching the slab. When I manually delete the mutual face it becomes a solid group.

Both objects in the picture are created with the same script.
