I adjusted the Drawing Units and Symbol Scale Factor, but the symbols are still not coming in at the correct size.

RainCAD inserts all symbols as AutoCAD blocks. A block can be composed of multiple objects drawn on several layers with various colors, line types, and line weight properties. For example, sprinkler symbols include the actual symbol on one layer, the arc pattern on a second layer, and the zone assignment attribute number on a third layer. These objects are combined together as a block and inserted into the AutoCAD drawing. To change the characteristics of the symbol, you must first purge all references to the block from the design screen. You cannot purge a block if the block is in use on the design screen. You must first delete any references to the block on the screen, meaning you must erase the symbols from the drawing. You can then use the Purge command in AutoCAD to remove the blocks from the drawing.
