GTA

Hi, I would like to insert a symbol at different scales in the same drawing, but I can't. To overcome this issue I have created a different but smaller symbol and placed it inside the first one. To switch them on or off, each one had a class attribute. This worked fine for three or four different scales. Now I have to do this massivly with new symbols - five symbols, twenty scales... To create/alter the symbols it is a time consuming task... Any help?
