Nonsolid object becoming solid when exported to Cura

[autumnalblues]

Thanks for all the tips, guys! Yes, I'll add some geometry connecting the free-floating eye and mouth.

Great, and please post photos of the finished print and cookies once you make them!

[autumnalblues]

I most definitely will.

Here is the finished cookie cutter, guys. Can't wait to try this on fondant and make sugar cookies!

Hello again, guys!

I'm making an Anna cookie cutter this time around. For the life of me, I can't figure out what's wrong with the model. I still have a lot to learn on Sketchup, indeed. The neck becomes solid when I export it to Cura. Kindly check attached files.

Would anyone be able to point out what's wrong with the model?

Thank you.

To check if any model is a solid you need select all of the relevant geometry and make it into Component [or Group].
Its "Entity Info" will not include the word 'Solid' in its header if it is not a solid.
Sadly it is not a solid.
It is racked with internal partition faces.
Use thomthom's Solid-Inspector to see the many issues.
My SolidSolver cannot fix it as the issues are two convoluted...
To fix it, edit it cut a section-plane looking down so you can see inside it.
Erase any internal facets and faceless edges [select+<del> key].
Remember that a solid object can only contain faces and edges, and every edge must have two faces - no fewer and no more !
Internal partition faces mean there will be edges with only one or more likely three or more faces.
There are some faceless edges, and you have a part meeting at a point - meaning that edge has four faces !
A little remodeling is needed

Thanks TIG. I really appreciate the help. I most definitely need to remodel Anna. Just a small favor: can you take a screenshot of the part that has four faces?

Fantastic! Thanks a lot, TIG.
