Dear Fredo6, Have tried every which way to download Lib Fredo6 with no results. Have auto downloaded from this website and Sketchup Warehouse. Have unloaded "all" your plugins and re installed latest version, but to no avail. Round corner and Visihole tool bars do not appear. Very frustrated after spending several hours attempting to reolve this problem. [image: Y2Vv_Capture.PNG]
