Resizing a Component

ebelg2000

Is there an easy way to resize a compenent, adding a uniform amount to each side? For instance, if I have a component that is 10" x 10", is there a way to add 1/4" to each side, changing it to a 10.5" x 10.5" other than by using push pull on each of the edges? Thanks

Scaling the component instance about it's center using Ruby is probably the easiest way to do it.

@mod = Sketchup.active_model
@ent = @mod.active_entities
@sel = @mod.selection
@vue = @mod.active_view
ci = @sel.grep(Sketchup;;ComponentInstance)[0]
if ci
 dims = UI.inputbox(["New Wid;","New Hgt;","New Dep;"],[ci.bounds.width,ci.bounds.height,ci.bounds.depth],"Resize Component")
 if dims
  wid,hgt,dep=dims
  xscl = wid/ci.bounds.width
  yscl = hgt/ci.bounds.height
  zscl = dep/ci.bounds.depth
  org = ci.bounds.center
  tr = Geom;;Transformation.scaling(org,xscl,yscl,zscl)
  ci.make_unique; ci.transform! tr
 end
end

Thanks, that's great, exactly what I had in mind and more. My problem now is I have absolutely zero knowledge of Ruby and therefore how to implement your solution. Any suggestions on how I might proceed would be greatly appreciated. Thanks again for your help

Question for ebelg2000: How complex is the component? Is it more than just a cube?

Select the Component Instance. Open the Ruby Console, Window>Ruby Console. Copy and Paste the code into the Ruby Console input and press Enter. You can repeat the process by selecting another Component Instance. Clicking the the Ruby Console input and pressing the Up arrow and then the Enter key.

This is a simplistic solution and will only work with Component Instances that are not rotated by some angle other than 90 degrees due to the bounding box expanding and contracting base on the rotation.

Dave, no nothing anymore complex. I had drawn a rectangular component as the start of a raised panel and then decided to change dimensions. As I was using push pull to add 1/4" to each edge of the panel I wondered if there was an easy way to accomplish the same thing.

Ah. Understood.

Not to take anything away from the script by sdmitch (it works a treat doing what it does) but be open to the idea of redrawing components when it makes sense. For a panel in a frame and panel door, it might actually be faster to delete the original geometry in the component and replace it with new geometry that is the right size. Also consider that the Move tool is often more appropriate than the Scaling for resizing.

Thanks guys for your input, I really appreciate it. Dave thanks for the comments an SDmitch thanks for the help. I did come across a post that led me to Fredos Scale tool that lets you scale a component to a specific dimension which seems to be just what I had in mind. Thanks again!
