Reading mm as inches

[chrisglasier]

point = Geom::Point3d.new 50,0,0
UI.messagebox(point)

The messagebox states (1270mm,0mm,0mm)

Window Entity, Model and Preferences are all metric.

Can anyone help please?

Hi,

Writing point = Geom::Point3d.new 50,0,0 means 50 inches on X axis
A numeric value (for coordinates,lengths, distances, etc) is always in inches (class Length) in SketchUp. That's weird but that's the way it is.

Just write point = Geom::Point3d.new 50.mm,0,0

Hope this helps,

Yes that's very good (given the imp/metric debacle) but now I have a problem (because I'm new to this)adding .mm to the variable in the following code:

def self.start
@dlg = UI::WebDialog.new("Nameset")

  @dlg.set_size 300, 180

  @dlg.set_file File.join(File.dirname(__FILE__), "openNames.html")
  
  @dlg.add_action_callback("find") {|d, p|
  a= p.split(",")
  subDir = a[0]+"/"+a[1]+"/"
  fileName = a[2]+".skp"
  theX = Integer(a[3])
  theY= 0
  theZ = 0
  
 point = Geom::Point3d.new theX,theY,theZ
 UI.messagebox(point)
  transform = Geom::Transformation.new point
  model = Sketchup.active_model
  entities = model.active_entities
  path = Sketchup.find_support_file fileName, subDir
  definitions = model.definitions
  componentdefinition = definitions.load path
  instance = entities.add_instance componentdefinition, transform
  view = model.active_view
  newview = view.zoom_extents
  }
  @dlg.show {}

I tried theX = Integer(a[3])+".mm" but no good.

Would be most grateful for more sagacity!

Hi,

Try this :-
theX = Integer(a[3]).to_mm

theX = Integer(a[3]).mm works.

I'm at GMT+8, so please accept delayed thank yous.
