When the weak separation condition implies the generalize finite type in ${\mathbb{R}}^d$

Let $\mathcal{S}$ be an iterated function system in ${\mathbb{R}}^d$, with full support and some restrictions on the allowable rotations. We show that $\mathcal{S}$ satisfies the weak separation condition if and only if it satisfies the generalized finite-type condition. With this in mind, we extend the notion of net intervals from $\mathbb{R}$ to ${\mathbb{R}}^d$. We also use net intervals to calculate the local dimension of a self-similar measure with the finite-type condition and full support.
