I need ( structural ) Parameter for walls & slabs to be type instead of instance because we always draw SE slabs & walls and forget to check this parameter
also, i think it will be great if we can change system parameters to be instance of type (or deleting from them) in our template file to match our need because @ my work we don't use them all and it consume some of the memory and processor
also when adding shared parameters to some thing like walls, i need to separate between basic walls and curtain wall
