Spiralize ignoring gaps in walls

[GregValiant]

Please see UM Cura #19230
@smartavionics seems to have found a hard coded number in line 15 in mesh.cpp that is having a negative effect by allowing the toolpath to ignore gaps in walls that have been put in place to keep islands from forming. This would have a negative effect on airplane prints and boat prints.

-->

Application Version
up to and including 5.7.2

Platform
Independent

Steps to Reproduce
This is reproduceable with the OP's project file.

Actual Results
The toolpath ignores some gaps while respecting others. Ignoring gaps results in an incomplete print and Spiralize fails.

Expected results
The gaps should be respected and the print should include all features and a spiral path.

Additional Information
Please see the referenced Cura bug report.

I can't find the bug report on this but it appears to be related. This model has slits of varying widths. Starting with the .30 slit they are ignored. The model dates from May of 2023.
