I have enabled the ceiling joist span table option in the system options. When I press the 'ceiling system' button and draw a joist area, it always frames it with the same height joist that is specified in System Options > Material Dimensions > Ceiling Options. Therefore, it draws everything, regardless of span, with 2x6 joists. When I double click the area, it brings up the joist properties and I have to manually select the span table to use. If it's a large room, once I select a span table, it will say "This span is too far, maximum span is XXX...." And then I have to manually change the size of the Joists. Is there a way to link a span table to the Ceiling Joist tool, so that when I draw a joist area, it will take the span, check the table, and draw joists the appropriate height automatically? When I draw a 20' room it will draw 2x12, a 10' room it will draw 2x6, etc. I see how to customize the span tables to meet my needs for span criteria, but I can't figure out how to make the software calculate joist size automatically when drawing. Going back and changing all the joists to the correct size after drawing them all isn't very efficient.
