CleanUp3 leaving massive files

Postby philem » Thu Jan 02, 2020 10:32 pm

Hi guys,
Can someone answer a question for me please ?

I have a 3D Printer and in the past when I have modeled in my CAD programme or downloaded a part from the net I have bought it into Sketchup to look at it and "clean up " by manually deleted excessive lines that create so many extra faces.

I then came across "CleanUp3" I think it was written by Thom Thom, my apologies if it was someone else.

I bought a model online all in STL format for a new spool holder for my particular printer, I bought them into Sketchup one by one to look at them and get them ready for printing ie: make sure they are the right orientation on the print bed, while I was there I thought I would give the models a clean using the extension. I did all of them and exported them again into the same folder with the same name but with "Mod" added so I know the modified ones.
When I went into the folder to get them ready to dump onto a flash drive to put into the printer the 'Mod files were massive, for example:

One piece was 15 KB before I cleaned it up but it came out as 3,423 KB after it was cleaned, I assumed it would be smaller because it was cleaned.

What am I missing?

A lot would depend on how the originals were created and what they are, they may well have been optimized for printing, 15kb is pretty small for a printable object. .stl is a triangulated format and removing the triangles in sketchup then re-exporting to an .stl will recreate those triangles. Also the object may have been created in a program that handles curves differently.

Do you not have printer software, can you not open the originals and orientate them there? Realistically you should only import into SU if you really need to modify them as each import/export has the potential to change things.

Hi Box,

Yes they were downloaded specifically for 3D Printing, also they were designed specifically for 3D Printing, I just thought it was a good idea to do this.

I will delete the modified files and just stick with the originals.

Thank you for replying.

I'd be interested to see one of the files to see what can be done, but as you bought them I doubt you'd want to share publicly. You could message one to me if you want, or a link to where you acquired them.

Hi Box.
I would be happy to share the file to see what can be done, what would be the best way to do this?
