Why does Cura think my models are completely solid?

· Why does Cura think my models are completely solid?
So sketchup specifies which part of every surface faces air and which side faces plastic. This information is stored in the STL file as something called a "normal". Your normals are backwards inside that part. In sketchup you can tell because the surface is gray instead of white. Right click on that surface and select "reverse faces".
If you are new to sketchup I suggest you switch to a solid modeling CAD versus sketchup which lets you create infinitely thin planes. Normal CAD software does not let you do that. Sketchup makes it work to seal up all solids - people often forget to seal in the bottom for example. But if you are a sketchup expert then definitely read the advice in the above link.

Ah thank you. On a sketchup forum I discovered it was actually the file format it was exported in. The faces were already right-side out, but I appreciate the link you provided.

Cura 5.7 is here and it brings a handy new workflow improvement when using Thingiverse and Cura together, as well as additional capabilities for Method series printers, and a powerful way of sharing print settings using new printer-agnostic project files! Read on to find out about all of these improvements and more.
S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
(Sorry, was out of office when this released)
This update is for...
All UltiMaker S series
New features
Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.
