xml-enclosed-surface

The xml-enclosed-surface geometry builder builds simple solid geometries.

This builder does not require any data parameters, and will construct the simple solid geometry from existing surface geometries. Thus, before the xml-enclosed-surface geometry builder is deactivated, other geometry builders should have been activated, passing their constructed surfaces to the xml-enclosed-surface geometry builder.

Each of the surfaces passed to the xml-enclosed-surface geometry builder should fully enclose a volume of space. The first surface accepted forms the outer boundary, and subsequent areas accepted form inner voids.

builder type: composite - accepts surface geometries

geometry constructed: simple solid

data parameters:

Data Name	Value	Required/Optional
demote-incomplete-geometry	This Boolean parameter determines if incomplete geometry should be demoted instead of producing an error. If set to true, whenever the geometry builder receives no surfaces to create a simple solid from, the simple solid will be downgraded to a null geometry. If set to false, whenever the geometry builder receives no surfaces to create a simple solid from, it will raise an error and terminate the translation. Range: true|false Default: false	Optional
coordinate-system	Specifies the coordinate system name. If the expression sequence for the coordinate-system evaluates to the empty string, then the coordinate system for the feature being built will not be set. Range: String	Optional
name	Specifies the geometry’s name. Range: String	Optional
