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.

Jim

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.

Jim

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.
