That isn't quite right.
An "aspect" is a partial view of something. If a mountain is in front of you, you see one "aspect" of it (you can't see the whole mountain). You can use "aspect" in many contexts, e.g.
1. There are several disturbing aspects to his character.
2. One of the most attractive aspects of this book is its fine illustrations.
A "respect", on the other hand, is a detailed view of something. You tend to find this meaning of "respect" only in certain set phrases, e.g. "in several respects", "in one respect", "in many respects":
3. In many respects, his character is quite disturbing.
4. This book is however quite attractive in one respect: it is very well illustrated.
All the best,
