Greetings, has anyone had problems with the curtainwall tool spontaneously losing all the frames on the inserted curtainwalls? I have a project with several types of curtainwall configs and the model keeps getting corrupted somehow and all the frames disappear on me. The support person at our distributor only suggestion was to create a new template file from scratch and merge the corrupted file into the new one. This solved the problem once, but now it has happened again. It seems that only the ones with modifications have gone bad. I.E. ones that I have inserted doors or customized frames. Any suggestions?
