Hello.
I am using Pro/TOOLKIT to connect to a Creo 8.0.5.0 session and to explore the active opened CAD file.
First of all, I need to retrieve the datum tags.
Here there is a skeleton of my program to do that.
ProEngineerConnect() ;
ProMdlCurrentGet() ;
ProMdlNameGet() ;
ProMdlTypeGet() ;
ProSolidSetdatumtagVisit(ProSetDatumTagVisitAction) ;
static ProError ProSetDatumTagVisitAction(ProSetDatumTag* pSetDatumTag, ProError, ProAppData AppData)
{
// Obtention du label du datum tag.
ProSetdatumtagLabelGet() ;
// Recherche des liens vers la géométrie à partir des références.
//
ProAnnotationReference* References(nullptr);
if (ProSetdatumtagReferencesGet(pSetDatumTag, &References) == PRO_TK_NO_ERROR)
{
int ReferencesCount(0);
if (ProArraySizeGet(References, &ReferencesCount) == PRO_TK_NO_ERROR)
{
for (int i = 0; i < ReferencesCount; i++)
{
switch (References[i].type)
{
case PRO_ANNOT_REF_SINGLE:
{
ProSelection Selection(nullptr);
ProModelitem ModelItem = { PRO_TYPE_UNUSED, 0, nullptr };
if (ProReferenceToSelection(References[i].object.reference, &Selection) == PRO_TK_NO_ERROR &&
ProSelectionModelitemGet(Selection, &ModelItem) == PRO_TK_NO_ERROR)
{
switch (ModelItem.type)
{
case PRO_AXIS:
case PRO_SURFACE:
{
Pro3dPnt ptDatumFrameLocation;
ProAnnotationPlane DatumFramePlane;
ProPlanedata DatumFramePlaneData;
ProSelection DatumAttachment(nullptr);
Pro3dPnt ptDatumAttachmentLocation;
if ((ProSetdatumtagTextPointGet(pSetDatumTag, nullptr, nullptr, ptDatumFrameLocation) == PRO_TK_NO_ERROR || ProSetdatumtagTextLocationGet(pSetDatumTag, nullptr, ptDatumFrameLocation) == PRO_TK_NO_ERROR) &&
ProSetdatumtagPlaneGet(pSetDatumTag, &DatumFramePlane) == PRO_TK_NO_ERROR &&
ProAnnotationplanePlaneGet(&DatumFramePlane, &DatumFramePlaneData) == PRO_TK_NO_ERROR &&
ProSetdatumtagAttachmentGet(pSetDatumTag, &DatumAttachment) == PRO_TK_NO_ERROR &&
ProSelectionPoint3dGet(DatumAttachment, ptDatumAttachmentLocation) == PRO_TK_NO_ERROR)
{
BUG ! -> ptDatumAttachmentLocation == {0, 0, 0} !!!!
If the datum tag is connected to a geometrical tolerance, the datum tag attachement location returned by Pro/TOOLKIT is null !
For more informations, you can refer to the following case which has been opened for this problem :

Is it possible to have a correction for this problem ?
Thank you.
Best regards.
