CBECCcom boost.geometry error

asked 2017-02-21 12:37:43 -0500

Has any one encountered and successfully removed a 'Boost.Geometry Overlay invalid input exception' error from a CBECCcom v3e 2013 model? This is causing and error when model is loaded and daylighting is not registering correctly for the impacted spaces. I've looked a coordinates and geometry, and tried to understand the planar geometry....but this is escaping me. Any suggestions?

Could you post the file? If it's not shareable, could you make a minimally complete model (one that opens and runs) of just one space that is having that error and share that?

Ok, so...couldn't stop thinking about this. After detailed examination of the walls and windows...nothing. Then I started looking at the Space polygons. The two spaces in question were a mess. Plotting the coordinates in Excel revealed that the spaces each had numerous duplicate vertices as well as vertices which were in the center of the space. (making a backup copy) and removing these 'problem' vertices fixed the problem. WOO

Moral here is that the error was not due to the wall/window, but due to the space polygon. Reviewing the OSM file from which the CBECCcom file was makes it appear as though the error occurred in translation. Keeping in mind, this was a running and compliant model, even with the error(s). We'll run again tonight and see how compliance goes.....
