Core: Features
The function ProFeatureIsNcseq() determines whether a feature
is an NC sequence.
The ProFeatureSolidGet() function provides the identifier of the
solid that owns the specified feature.
The ProFeatureChildrenGet() and ProFeatureParentsGet()
functions get the children and parents of the specified feature. For
these functions, the parent of a feature means a feature it directly
depends on, and a child is a feature that directly depends on it. This
differs from the Pro/ENGINEER command Info, Feat Info, which
also shows indirect dependencies.
The function ProFeatureSelectionGet() is used for features that
were created in a part as a result of a feature in a parent assembly.
For example, if you create a hole in Assembly mode, then select a
part to be intersected by that hole, the geometry of the hole is
visible to Pro/TOOLKIT as belonging to the part, even if the
original feature is specified as being visible at the assembly level.
This geometry—a list of the surfaces forming the hole—belongs to a
feature in the part whose type is PRO_FEAT_ASSEM_CUT. The
function ProFeatureSelectionGet(), when applied to that part
feature, identifies the assembly, and the path down through it to
the part in question, which contains the original feature.
During regeneration, Pro/ENGINEER performs geometry checking
to prevent regeneration errors. The geometry check process
identifies features that could cause problems if the part or assembly
is modified, but which do not cause regeneration failure in the
model in its present state. The ProFeatureHasGeomchks()
function outputs a variable of type ProBoolean that indicates
whether a particular feature, identified as an input argument to the
function, has geometry checks.
The function ProFeatureIsReadonly() provides information
about the read status of the specified feature. Its first argument is a
pointer to the feature’s (ProFeature) handle. If the feature is read
only, the function outputs a ProBoolean with the value
PRO_B_TRUE; otherwise, the value is PRO_B_FALSE.
The feature ProFeatureIsEmbedded() identifies whether the
feature is an embedded datum. Embedded features are visible in
the model tree, but cannot be used as reference parents for features
other than the feature into which they are embedded.
