I've been working on a new template for 2012 AMEP. Some how I lost the schematic plumbing elbows styles (all). If I switch to a mitered fitting they apear. Selecting the mitered fitting, then edit the fitting style through the properties pallet, even the edit fitting dialog preview referencing elbow fittings are missing from the display? Is it possible I deleted the dedicated layer/s for schematic elbow styles when clean up the template?
