I use some 3rd party symbols in my drawings and also use standard symbols I have created. When I use either the design center or tool pallet (AutoCAD2005) to insert the 3rd party symbols, the symbols are automatically scaled to the scale factor of my drawing. But when I insert my own symbols, I have to specify the scale factor. All symbols are drawn at 1 to 1. What do I need to do to get my symbols to automatically scale to the drawing scale factor like the 2rd party symbols?? Thanks Tom
