Using the Automation function through .DAT files I can only cluster a LH version of a part in sheet metal manufacturing. ProE will custer two LH parts together but the RH Mirrored image will only place one part per sheet. I have submited a SPR to PTC... the only response back was to change the Angle setting to 1 Deg. This results in the Rh version clustering two per sheet but now ProE only place one LH version per sheet. Has anyone else experienced this problem????? The parts are not complicated geometry... ProE should be able to cluster both mirrored images the same Way!!!!!!
