Get Dimmensions plugin

[dedmin]

Can somebody improve this very useful plugin? When the component is not aligned with the wold coordinates the reported dimensions are not accurate! Thanks in advance!

GetDimensions.rb

Use .local_bounds instead of .bounds to get the BB in the first place.

boundingBox = model.selection[0].local_bounds

Wait... that doesn't seem to account for scaling... so it's not what I thought.

This is based on code from Didier and TIG. It should work for selected Groups and Instances in any context, although I only tried it at model level.

model = Sketchup.active_model
entities = model.entities
selection = model.selection

e = selection[0]

scale_x = ((Geom;;Vector3d.new 1,0,0).transform! e.transformation).length
scale_y = ((Geom;;Vector3d.new 0,1,0).transform! e.transformation).length
scale_z = ((Geom;;Vector3d.new 0,0,1).transform! e.transformation).length

bb = nil
if e.is_a? Sketchup;;Group
  bb = Geom;;BoundingBox.new
  e.entities.each {|en| bb.add(en.bounds) }
elsif e.is_a? Sketchup;;ComponentInstance
  bb = e.definition.bounds
end

if bb
  width  = bb.width  * scale_x
  depth  = bb.depth  * scale_z
  height = bb.height * scale_y
  puts "#{width}, #{height}, #{depth}"
end

Thanks, but where to put this code?

could someone post a screen shot of what this plug does? sounds very interesting.

Just pops a dialog showing the dimensions of the selected Group or Component.

ahh, bounding box dimensions. i was hoping it was some kind of auto dimesioning thing.
thanks guys.

I sent a plugin to dedmin to try. It shows the dimensions of a selected group or instance correctly eve when scaled and rotated. I'll post it when I hear back.
