I totally understand and appreciate the ability to create custom shaped extrusions. However, I count no less than 27 sizes of square steel tubing smaller than 1 1/4" available right now from my steel supplier. This is just one of the many common shapes that start at larger sizes than what I commonly use. Why does Inventor's library arbitrarily start at arbitrary sizes, ignoring everything smaller than it? Expecting every user to custom make every COMMON size of extrusion is unfortunate on a CAD platform that is otherwise so amazing. This issue comes up often enough that I feel the need to set aside a LARGE chunk of my time to create a FULL library of steel extrusions smaller than what Inventor offers.
