Here is my skp file.

My style is the default style, the hidden line mode is off. i just turn on the monochrome style to check if my model have any backface showing on the outside. Its just super weird to see some object is fliped in 3ds max even though they have the same material and all correctly face outside.

I know that i can reverse face inside sketchup but all of my face is flipped correctly.

I checked it with monochrome style and they are all turned white
But when i import it into 3ds max to apply some uvs, some of the object is flipped.
Green show face is backward.

and this is what happen when i port it to stingray, all the backface is invinsble and i can see the inside of the object.

I relly don't understand how 3ds max import work my model to that. Is there anyway i can fix this? I can send the sample of my model if you want.

Hello, sorry for digging up years old thread. I wonder if anyone can help this work with the newest version of sketchup.

oh man, i have found it. it was Eneroth Solid Tools
https://extensions.sketchup.com/en/content/eneroth-solid-tools

I swear that i saw it in sketchucation plugin store but now it only available in sketchup official plugin store. Also thanks Dave, i'll use that plugin too.

This is quite a silly post so forgive me but i seem to have lost my memory and can't remember what that plugin name anymore. I recently reinstalled windows and everything so i need to reinstall my plugins as well. Im using sketchup 2016 windows.
Im looking for a solid tool (trim, cut boolean...) plugin that i have randomly installed through sketchucation. it does what default solid tool on sketchup do but better, it can cut through complex model etc... I have spent hours looking through the plugin store and couldn't find it.
it also has it own tool bar and icon similar to the default solid tool toolbar. I have used it before on sketchup 2015, and im sure it isn't Boolean OSCoolean because it only work with sketchup 2013. Please help!
