When adding drawings into StructionSite, people typically expect drawings to be ordered in alphanumerical order.
Level 1
Level 2
Level 3
etc...
However, an issue may come up with you have more than 9 drawings. When you get into the double digits, you may notice that the drawings are ordered as the following:
Level 10
Level 11
Level 12
Level 1
Level 2
Level 3
etc...
In order to make the drawings order correctly, you'll need to add a "zero" in front of the single digit numbers, like so:
Level 01
Level 02
Level 03
...
Level 10
Level 11
Level 12
That should ensure that drawings are always ordered in proper expected alphanumeric order!
