Hi Snomojo23,
You can set it by default in your project by doing the following :
1. In 2015 version, go to "Systems" menu, select "Flex Duct" from HVAC group (as attached file, image 1).
2. From properties box, select your desired Flex Pattern (as attached file, image 2). Start using the selected flex pattern in your project by clicking in your screen, you can just hit Esc key after clicking to discontinue or you can just continue using the flex duct. The point is once you have done that it will now be your default Flex Pattern every time you use it.
You can do the same procedure in your template, make it by default by doing item 1 & 2 above and save your template. Everytime you start with a new project using the template, it will always be your default Flex Pattern.
