understanding the insertion point
The insertion point of a family is important for three main reasons.
▶
A family will flex around its insertion point; therefore, the insertion point
is maintained when the family's dimensions change.
▶
If you need to replace one family with another of the same category, they
should swap at the same insertion point. Otherwise, if you have a family
with an insertion point that is at a corner and swap it with another fam-
ily whose insertion point is at the center, all the instances of that family
throughout your project will shift.
▶
If you need to adjust the default elevation when placing some types
of families (such as wall-based families), you can change the reference
elevation.
