I’m trying to access the sketch/drawing data of the model included in sample data at “data/CV5\_Aquo\_Bottle/"\_Aquo Bottle.CATProduct”

From a DrawingBlock reference, I run the following code:

```void
	if (pDrwBlock == nullptr) {
		return;
	}
		
	A3DDrawingBlockBasicData drwBlockData;
	A3D_INITIALIZE_DATA(A3DDrawingBlockBasicData, drwBlockData);
	A3DStatus status = A3DDrawingBlockBasicGet(pDrwBlock, &drwBlockData);
	if (status != A3D_SUCCESS) {
		return;
	}
	
	std::cout << " Entities: " << drwBlockData.m_uiDrwEntitiesSize 
	          << ", Markups: " << drwBlockData.m_uiMarkupsSize
	          << ", Nested Blocks: " << drwBlockData.m_uiDrwBlocksSize << std::endl;
	
	if (drwBlockData.m_uiDrwEntitiesSize > 0) {
		std::cout << " Drawing Entities:" << std::endl;
		for (A3DUns32 i = 0; i < drwBlockData.m_uiDrwEntitiesSize; i++) {
			if (drwBlockData.m_ppDrwEntities[i]) {
				A3DEEntityType entityType = kA3DTypeUnknown;
				if (A3DEntityGetType(drwBlockData.m_ppDrwEntities[i], &entityType) != A3D_SUCCESS) {
					return;
				}
				std::cout << entityType << std::endl;

```

Most of the referenced draw block entities from this sample file have A3DEntityType=1315. This value does not seem to match up to any enum values in the [docs](https://docs.techsoft3d.com/hoops/exchange/api/c/enums/A3DEEntityType.html#c.A3DEEntityType) but it just overshoots the kA3DTypeDrawing range (1300-1314). I’m wondering, is there a definition for this type that I am missing, or is 1315 simply an undefined drawing entity?

For clarity, I am using the enum headers from the trial code

Generally, the range of expected type values is known before calling `A3DEntityGetType`. In this case, you’re expecting one of the `kA3DTypeDrawing*` values. When the actual value returned is outside this expected range, it generally means an unexpected result or unknown type related to this range.

Hello,

An entity type value outside the expected range means this imported structure is not exposed by our API for some reason.

It should be safe to use `A3DDrawingCurveGet()` on these entities if you want to access the data.
