Add an array of entities to a set.

Add existing gentities to the gentity_set (do not create them). Note that if a gentity of dimension d>0 is added to the gentityset, the lower-dimensional gentities that bound it are not automatically associated with the gentityset.

Parameters:

gentity_set	Set being added to
gentity_handles	Gentities being added to gentity_set

		iBase_EntitySetHandle	entity_set_to_add,

	)

Add an entity set to a set.

Allows the user to explicitly add one or more gentity_sets to another. This automatically sets the contained in relationship, but not the parent/child relationships. All gentity_set handles are automatically contained in the parent mesh interface, so passing in NULL as the first argument results in no action.

Parameters:

gentity_set	Set to which other sets are being added
gentity_set_handles	Sets added to gentity_set

Create a cone or tapered cylinder.

Create a cone parallel to the z-axis and centered at the origin (so that its z-coordinate extents are +height/2 and -height/2). The 'base' of the cylinder is at z = -height/2, and the top is at +height/2.

Parameters:

instance	iGeom instance handle
height	The height of the cone.
major_rad_base	The x-axis radius at the base of the cylinder
minor_rad_base	The y-axis radius at the base. If minor_rad_base is 0, the cylinder will be circular (as if minor_rad_base == major_rad_base)
rad_top	The x-axis radius at the top of the cone. The y-axis radius at the top of the cone will be inferred to keep the aspect ratio of the top of the cone the same as the bottom. If rad_top is 0, the cone terminates at a point.

ITAPS_API void iGeom_createEntSet	(	iGeom_Instance	instance,
		int	isList,

Create an entity set.

This function allows a new gentity_set to be created. The user may set the multiset, ordered, isMesh, flags as needed; otherwise default values (all false) will be used. On creation, Entitysets are empty of entities and contained in the parent geometry interface. They must be explicitly filled with entities using the addGentities call and relationships with other Entitysets must be done through the addEntityset and parent/child relationship calls.

Parameters:

multiset	If true, gentities can appear more than once in this gentity_set
ordered	If true, order of addition and removal is maintained for this gentity_set
gentity_set_created	Entity_set created by this function

Create a tag with specified name, size, and type.

Create a tag handle with a given name, size (in bytes), and default value. The tag name is a unique string; if it duplicates an existing tag name, an error is returned. The tag_handle is returned as an opaque value which is not associated with any mesh gentities until explicitly done so through one of the 'AddTag' functions defined later.

ITAPS_API void iGeom_destroyTag	(	iGeom_Instance	instance,

Destroy a tag.

Delete a tag handle and the data associated with that tag. The deletion can be forced or not forced. If the deletion is forced, the tag and all of its associated data are deleted from the implementation even if the tag is still associated with mesh gentities. If the deletion is not forced, the tag will not be deleted if it is still associated with one or more mesh gentities. In this case an error is returned asking the user to remove the tag from that gentity before deleting it. If the underlying implementation does not support the requested deletion mechanism, an error will be returned.

Get tag values of arbitrary type for an array of entities.

Get tag values of arbitrary type for an array of entities. Tag data is returned as void*. tag_values_size specifies the size of the memory pointed to by tag_values in terms of bytes. Applications may use this function to get data of any type, not just iBase_BYTES. However, because this function supports data of arbitrary type, in all cases the size specified by tag_values_size always in terms of bytes.

Parameters:

instance	iGeom instance handle
entity_handles	Entity array on which tag is being set
entity_handles_size	Number of entities in array
tag_handle	Tag being set on an entity
*tag_values	Pointer to tag data array being returned from function. Note that the implicit INTERLEAVED storage order rule applies (see section ITAPS Storage Orders)
tag_values_allocated	Pointer to allocated size of tag data array
tag_values_size	Pointer to occupied size in bytes of tag data array
