In a situation if you want to have number of planes, which are parallel to each other, there are two ways to create planes:
-You can create a new plane, which has an origin plane as a reference plane or
-You create a new plane, which has a plane you created before as a reference plane.
Which is better. I assume it is good to have an origin plane as a reference plane because when editing it avoids model fails and model will be more robust.
What is your experience?
