Is there a way to limit where fill is done within a print. I am trying to print BOTW Shrine from Thingiverse. It appears to be as a rock formation with an entrance to a cave like opening. The problem is if I do no infill, the flat area outside the entrance and walkway in area have no support and if I enable infill, the entire cave is filled. Any help would be greatly appreciated, Grandson disappointed with 1st failed print. BTW this downloads as a huge size and i scaled it to 4% to have it fit my build plate.

Also, if I enable supports, no support is generated under these surfaces.

Clarify things, make a screencapture and point out your "problem".  I opened the file in cura, had to scale it to 2.5% to fit my buildplate!

 

Can't see why it is not possible to print... cave is open, doesn't change with high or low infill-percentage... and since it is flat on the buildplate there is no need for support...

Mari, thank you for the help. If you preview line by line from the build surface up, you will see the bottom layers, and then the sides build to the point in my settings at layer 140 the flat surface going into the cave appears. there is only empty space under that surface and the print fails. I hope you can see from my picture.

When I use infill, it fills the entire cave. My question originally was< Is there a way to limit the infill. Could I have infill up to layer 139 and not beyond? Or could I have infill only under the unsupported floor?

Don't think so... show me the setting you use...  "My" cave is open as you can see!

You were correct, I though I had seen a photo where the entire area inside the outer shell was open space. I am Technology challenged.🤕
