## Method List

ConvertToPrimitive ()
Convert the geometry into its primitive base form, returning a new part without the concrete type properties. The reference to the original part will become invalid. (Returns a Geometry object.)
CopyAndMirror (properties table)
Apply a copy and mirror using a table defining the properties. (Returns a Geometry object.)
CopyAndRotate (origin Coordinate, rotationaxis Coordinate, angle Expression, count number)
Copy and rotate the geometry. (Returns a List of Geometry object.)
CopyAndRotate (properties table, count number)
Apply a copy and rotate using a table defining the properties. (Returns a List of Geometry object.)
CopyAndTranslate (from Coordinate, to Coordinate, count number)
Copy and translate the geometry. (Returns a List of Geometry object.)
CopyAndTranslate (properties table, count number)
Apply a copy and translate using a table defining the properties. (Returns a List of Geometry object.)
Delete ()
Delete the geometry.
DeleteMesh ()
Deletes the geometry's associated simulation mesh.
Duplicate ()
Duplicates the geometry. (Returns a Geometry object.)
Explode ()
Explode the geometry into separate surface and edge parts. The new parts represent a snapshot of the geometry at the time it was exploded. (Returns a List of Geometry object.)
GetProperties ()
Returns a table of properties representing the state of the object. The properties table can be used with the SetProperties method to change multiple properties of the object in one step. (Returns a table object.)
ReEvaluate ()
Re-evaluate the model by initiating the mapping algorithm. The algorithm keeps track of the individual items when the geometry is modified. Models created in earlier versions of CADFEKO versions may not contain all the mapping information. As a result some items may be marked suspect.
ReverseFaceNormals ()
Reverse the geometry face normals.
ReverseFaceNormals (faces List of Face)
Reverse the geometry face normals.
SetProperties (properties table)
Modifies the state of the object using the provided table of properties. This method is used to modify multiple properties of the object in a single step.
Unlinks the geometry's associated simulation mesh. (Returns a Mesh object.)

## Static Function List

GetDefaultProperties ()
Creates a table containing the default settings to create an object. (Returns a table object.)
