Need Help Fixing Model

Postby solocircuit » Fri Aug 29, 2014 2:21 pm

Hello there!,

I am new to the forums here and model making in general I am currently trying to make a laptop using the odroid u3 and touch screen in sketchup but when I go to upload it to Ponoko I get a messy mesh error. So after some research I downloaded the solid inspector plugin, It looks like there is only a couple errors to fix but I do not know how to go about fixing them and it's so annoying. If anyone would be so kind as to help fix the errors it would be much appreciated!

Solid -> two faces for every line...

Your construction has up to 4 faces for several lines and internal faces!

Use the Cleanup plugin to get rid of those extra faces you have piling up on each other. What is happening is that often when you delete a line and redraw it, or if you draw two lines on top of each other, SU will make two faces on top of each other (even though everything "looks" normal). You have to go through and delete these extra faces or just run Cleanup plugin to get rid of them.

But, that aside...
You have to think of 3D print modelling just like you would be building something in real life. Every wall has to have a thickness: in other words, a FACE is NOT a wall. A wall must have two sides and a middle (thickness). 3D printing does not know what to do when you just have a single face because it sees this as a piece of geometry without any solidity.
