Create Markups

It is assumed that before creating a markup, the following have been created: file structure (OdPrcFileStructure &newStructure), product occurrence (OdPrcProductOccurrencePtr &newProductOccurrence), tessellation data related to the markup (OdPrcMarkupTessPtr mTess), and markup leaders array (OdPrcMarkupLeaderPtrArray arr_leader). In addition, it is assumed that the name of the markup was provided (OdPrcName name).

Add markup leader IDs to the product occurrence markup leader IDs array. Leaders are added to the file structure:


          OdPrcObjectIdArray &leaders = newProductOccurrence->markups().leaders();
          leaders.resize(arr_leader.size());
          for(OdUInt32 f=0;f<arr_leader.size();++f)
          {
            newStructure.addObject(arr_leader[f]);
            leaders[f] = arr_leader[f]->objectId();
          }

Add markup leader tessellation data to the file structure tessellation:


          if (leaders.size() > 0)
          {   
            newStructure.fileStructureTessellation().tessellations().push_back(arr_leader[0]->tessellation());
            if (leaders.size() == 2)
            {
              newStructure.fileStructureTessellation().tessellations().push_back(arr_leader[1]->tessellation());
            }
          }

Create a new instance of the OdPrcMarkup class and add it to the file structure:


          OdPrcObjectIdArray &arr = newProductOccurrence->markups().markups();
          OdPrcMarkupPtr markup = OdPrcMarkup::createObject();
          newStructure.addObject(markup);

Set markup attributes (name, type, tessellation data):


          OdPrcGraphics graph;
          markup->name() = name;
          markup->graphics() = graph;
          markup->setType(type);
          markup->setSubType(subtype);
          markup->tessellation() = mTess;

Add leaders to the markup:


          OdPrcObjectId un_id;
          if (leaders.size() > 0)
          {
            un_id = leaders[0];
            markup->leader().push_back(un_id);
            if (leaders.size() == 2)
            {
              un_id = leaders[1];
              markup->leader().push_back(un_id);
            }
          }

The ID of the newly created markup is added to the product occurrence markup IDs array (storing all markup data for a product occurrence is implemented in the OdPrcMarkups class):
```
            arr.push_back(markup->objectId());        
        
```

Create annotation items for the markup and set its attributes:


          OdPrcObjectIdArray &arr_entity = newProductOccurrence->markups().annotationEntities();
          OdPrcAnnotationItemPtr ann_item = OdPrcAnnotationItem::createObject();

          ann_item->name() = name;
          ann_item->graphics() = graph;

Link the created annotation item with the markup by specifying the markup ID:


          un_id = markup->objectId();
          ann_item->markup() = un_id;

Add the annotation item to the file structure and product occurrence annotation item IDs:


          newStructure.addObject(ann_item);
          arr_entity.push_back(ann_item->objectId());

Add markup tessellation data to the file structure tessellation:


          newStructure.fileStructureTessellation().tessellations().push_back(mTess);

Creating different types of markups is illustrated in the OdPrcCreate sample application.
