Hi, as far as I know the precision was increased to 10-12 because of errors when inserting a window into a wall which is not exactly aligned with the axes. There were problems with the window vertices that they fall outside the wall plane if the precision is too low.

Von: trnsys-users-bounces@cae.wisc.edu [mailto:trnsys-users-bounces@cae.wisc.edu] Im Auftrag von vincent.coste@amoes.com Dear all, Do you know if it is possible to reduce the vertices coordinates precision (10-12 m by default). I tend to think that 10-3 m is enough and it could reduce errors in surfaces matching. Any idea ?
