Rotation about the origin

[rossthompson]

Hi guys,

I am trying to write a script that very simply rotates selected objects by 90 degrees in the Z axis. I have put together some code but it isn't working. Can anyone help? I am new to Ruby so I have probably made some really basic mistakes.

require 'sketchup.rb'


# Add a menu item
UI.menu("PlugIns").add_item("rotate90") {  
  rotate90	# Call method.
}

def rotate90
	rv = Geom;;Vector3d.new(0,0,1)
	ra = 90.degrees
	rp = Geom;;Point3d.new(0,0,0) 

	Sketchup.active_model.Transformation.rotation(rp, rv, ra))
	
end

require 'sketchup.rb'


# Add a menu item
UI.menu("PlugIns").add_item("rotate90") { rotate90 }  # Call method.

def rotate90
   
   mod = Sketchup.active_model
   ent = mod.entities
   sel = mod.selection

   rv = Geom;;Vector3d.new(0,0,1)
   ra = 90.degrees
   rp = Geom;;Point3d.new(0,0,0) 

# define the rotation transformation
   trr = Geom;;Transformation.rotation(rp, rv, ra)
# apply the rotation transformation to the selection
   ent.transform_entities(trr,sel.to_a)
   
end

You were close. Use http://code.google.com/apis/sketchup/docs/index.html to help with syntax.

Sam,

Thanks very much that works perfectly.

Are you planning to build on your programming skills and add functionality to this?

What I have always found really frustrating is when you use the group/component 'handles' to rotate components. It is a neat time-saver, but for years I have always wanted to rotate about a component's origin.

Alternatively if anyone else out there has a plugin that does this, I would be grateful if someone could please point me in its direction.

Check out Rotate&Scale on my blog. It works with groups and components and rotation is about the origin.

Perfect for mapping to a shortcut key.
