Just now I created a simple box, rec @8,8 saved it as an R12 dfx, tried to load it into LCam, no go. So I exploded it into segments, still no go. Well hmmm lets purge, only had layout blocks, purged anyway. Only one layer on a new file so there shouldn't be any hidden thingys. I saved a R12 as everything works with R12. What is up with this? I must admit that I am more used to using the dwg file as Microvellum is integrated with ACad and reads this file real time. What am I doing wrong?
