Constraints in Options
You should take the following things into consideration when
adding constraints to an option:
- Solving options activates the dimension constraints, but does
not remove overlapping constraints. For example, the bay window
roof may have an overhang constraint, which has already been
defined for the main roof. In this case, an overdefined model is
resulted in option solving. The constraint can be used to position
the roof, but it should be removed before solving the options.
- Constraints of roof accessories may be lost when the roofs are
merged in option solving.
- An option may have constraints to components outside the
option. The non-active options are highlighted in grey in the list
of the Constraints of Object dialog box. However, you should
consider how to ensure controlling the model when adding
constraints. For example, a dimension constraint between two
options may cause a too complicated model.
