How can I change the default type setting for flex duct?
I've changed my display properties to show all flex duct as single line. When I did that it changed all my flex duct to the from what I preferred to the wavy S appearance. I've looked everywhere and cannot find where the setting is. If I look in the duct preferences on the duct pallete, it's set to a different type which is not showing up. Does anyone know where the setting is I need to change so that it will modify all the flex duct within the drawing?

It appears all newly drawn flex comes in as shown on the duct preferences. Looks like I can just select all my existing flex and perform a Flex modify properties to get my preferred type. Apparently the S flex must have been the 1-line default when I orginally drew the flex. Since I was using the 2-line display I didn't see that. Then when I switched my flex to 1-line display it all got converted over. Makes sense now that I think about it. Just make sure when drawing your flex that both 1-line & 2-line are set to the appearance that you prefer. Regards, Jmcfaddn
