Makes as much sense as anything can given the restrictions, since a moderator will take action if you USE a design to show HOW something can be designed.
There is nothing wrong with using a design to show how things can be designed. Just remember that fan designs go in Fan Designs. A very simple rule, extremely easy to follow.
This rule is actually for Catalyst's protection. The developers do NOT go into Fan Designs/Rules/Etc, and this way they avoid the kind of grief that comes when a TRO comes out and a unit coincidentally matches or bears a strong resemblance to a fan design posted in that section, and said fan demands credit or recompense.
Don't laugh, this has happened, and you can thank those bad apples for ruining things for everyone else.
