      The statistics are after purging everything and then saving. That whole process I performed many times. Since I posted this I ran cleanup on both models, It found a few duplicate faces and stray lines in each and I then purged and saved again. Only slight changes in file size. 😕 Also the dropbox links are there for the models if your interested. Thanks for the input!

        I'd use the smaller file, if there's no advantage to the bigger one. Keep the bigger one in storage in case there's a hidden glitch.

          The smaller one was what I was using in my main model of the house(there are over 100), the bigger one is what I modified for 3d printing. I mostly wanted to use it to avoid any future confusion. For now though I think that's all I can do.

          Thanks!

            you also used 'Thru Paint' and 'Twilight' on it and they left a number of embedded attributes...

            even when purged the file size remains disproportionate to the minor changes between the two files, so I believe the attributes 'have' corrupted the file...

            I've noticed this before with 'Thru Paint' but can't quite see what goes wrong...

            I would remake the 3d print version from the original and not 'play around' before saving it as a component...

              Thank you! How did you know that? That is very interesting!
              I just ran through paint on it, setting it to paint the default material an all connected faces and it dropped the file size by 3mb. Also ran "Clean All" from the Twilight menu but no change in file size. Thanks for checking it out!

                I run Enroth's Attribute Inspector on both to see what was there...

                I used it to 'clear' those found, but it didn't make it any smaller, hence I recommended remaking...

                    Interesting problem.

                    I was able to make the big file 2,8Mb again by doing:

                    1. explode the group
                    2. use 'show hidden geometry' and select everything (including the invisible edges )
                    3. assign a default material to everything -> saves 3Mb
                    4. run this ruby code in the ruby console to remove any attribute on any entity (delete the lines with the 'puts' if you dont want to report everything in the Ruby console. -> saves 4 Mb (dont forget to close the Outliner or it will slow down the execution of the code)
                    model = Sketchup.active_model
                    sel = model.selection
                    
                    sel.each {|s|
                    	attrdicts = s.attribute_dictionaries
                    	if attrdicts
                    		attrdicts.each{|d|
                    			puts attrdicts,d
                    			attrdicts.delete d
                    		}
                    		
                    	end
                    }

                      That is amazing! Thank you so much for that! I find it interesting that when I selected everything and changed the default material in the Entity Info window and saved no change. But when I select everything and use the paint bucket and save... then I get the file size reduction.

                      Really appreciate all your help!
                      Thanks!

                        I ran a modified version of kaas's code and it shows every faces has it's own attribute dictionary...

                          Thanks so much! Now I see what you were saying about ThruPaint. This will help model performance greatly!

                          Thanks again for all your input!

                            I will republish with an option to erase all attributes, when the user judges that the painting is OK.
