Re: Sample plugin does not start
Right, I think my exe file is not up to date. Fine now though.
BTW, I modified your plugin Compute Walls Surface for my purpose and just for it (being messy of course), still I post it here if anyone bother to test or use it.
don't know how to attach a file

//version 25 Dec 2014
//- added ability to approximate curved walls
//- added ability to work for multilevel building
//- corrected slope walls
//- filter openings substractions by Doors & windows only
//- approximate doors & windows positions to prefer more inclusions. CAUTION: may have side effects when a door or windows is in vicinity of more than one wall on any level
