amont 0 Posted January 26, 2017 in Cura 2.3.1 not recognizing holes Cura 2.3.1 is not recognizing vertical holes (stopped and full) in object. These holes are recognized in earlier versions of Cura. Curiously these holes are recognized when the object is turned through 90 degrees in Cura 2.3.1 (this is not a practical orientation in which to print the object). This problem needs to be fixed.

peggyb 136 Posted January 26, 2017 in Cura 2.3.1 not recognizing holes can you check in the view mode (left on your screen, eye) the x-ray, to see if there is something in your CAD model invalid. second you can check what settings are enbled/disabled in the Mesh fixes (preferences-settings) Share this post Link to post Share on other sites
amont 0 Posted January 26, 2017 in Cura 2.3.1 not recognizing holes Nothing comes up in x-ray mode, no boxes are ticked in Preferences - mesh fixes. Share this post Link to post Share on other sites
DaHai8 67 Posted January 27, 2017 in Cura 2.3.1 not recognizing holes Can you post your STL and/or a screenshot in Cura so we can see exactly what is happening? Share this post Link to post Share on other sites
peggyb 136 Posted January 27, 2017 in Cura 2.3.1 not recognizing holes then tick the 'union overlapping volumes', if that doesn't help, try the others one by one. Share this post Link to post Share on other sites
amont 0 Posted January 27, 2017 in Cura 2.3.1 not recognizing holes I have been through all the Mesh fix options without success. Here are some screenshots. [media=31499] [/media] I cannot find out how to attach the stl file. Share this post Link to post Share on other sites
DaHai8 67 Posted January 27, 2017 in Cura 2.3.1 not recognizing holes First thing I see is your faces are reversed. That's why it shows red on the top of the object when laying flat. When you view it in x-ray mod, do you see any red areas then? Those are manifold errors. Did you design this in SketchUp? If so, install the Solid Inspector2 and use it to check and fix your model.

amont 0 Posted January 27, 2017 in Cura 2.3.1 not recognizing holes Thank you DaHai8 - this has cured the problem but also leaves me wondering quite what is going on. No red appeared in X-ray mode. I use Cinema 4D. I reversed all the normals on the main body (not the holes) which were showing all facing the same way, which fixed the problem, but again when in Cura one of the large flat faces is showing in red suggesting it thinks the normals on the two large surfaces are not facing the same way (inward/outward). I am surprised turning through 90 degrees should have any effect on a problem like this, and why do earlier versions of Cura not have a problem? Thanks for the help.
