# 1. Material lists and constituents may have shape aspects and I
|

|
# haven't implemented it yet.
|
||
|
|
# 2. Material layer and profile sets implicitly define parametric
|
||
|
|
# geometry and we have no way of guaranteeing that this constraint is
|
||
|
|
# satisfied.
|
||
|
|
# 3. Material set usages follow an unofficial constraint that all
|
||
|
|
# instances must have a usage of their type's material set. We cannot
|
||
|
|
# guarantee that constraint.
