dbCreateSnapBoundary

dbCreateSnapBoundary(
d_cellViewId
l_points
[ lt_edgeNames ]
)
=> d_boundaryId / nil

Description

Creates a snap boundary in the specified cellview.

Placement tools use the snap boundary to place instances of the cellview in rows. Depending on rotation and symmetry, the appropriate corner is snapped to the site in the row. A snap boundary must be an rectangle, therefore the number of points in the point array should be four. A cellview can only have one snap boundary.

Arguments

d_cellViewId	The database ID of the cellview.
l_points	Specifies the points of the snap boundary.
lt_edgeNames	Optional argument that list the names of edges.

Value Returned

d_boundaryId	The database ID of the snap boundary if the creation is successful.
nil	If a snap boundary already exists for the cellview, a warning is generated and nil is returned.
