We are currently on Rev 17. I thought you used to be able to convert a part to sheetmetal. The help says to go to the "Convert to Sheetmetal" icon on the feature menu, but it's not there. If you go to the file menue, it shows the convert to sheetmetal option, but it is not available. Didn't there used to be an "Environment" menu at the top that had a pull down for sheetmetal? Is you create a sheetmetal part, you can switch from SM to Part and back again, but now you must start from "Sheetmetal"? Anyone know what's going on?
