Hard to tell simply by looking the code. In general it is customary to test fixes before submitting them.

It just compiled fine it but I don't have the IFC file you observed the issue to test it with.

Should be observable with any file, simply use e.g. --verbose --center-model.

Could you please copy-and-paste your IfcConvert output please?

Seems to be fine with a test IFC file I'm using.

>IfcConvert.exe ..\..\test\input\acad2010_objects.ifc --center-model --verbose

@Stinkfist0 Yes it fixes it.
