Wall Quantities Extraction

Apollos — Mon, 16 Sep 2024 12:51:01 GMT

Dear fellow Archicad C++ Users,

I am trying to extract the Quantities of walls (particularly composite walls). I followed the example folder Element_Snippets. But I am stuck, please I need help. I have tried several code setups some crashed but only this one gave me a WriteReport Dialog page but with Wall GUIDs but no Composite as output.

Please here is my code, any useful help and guidance is appreciated.

void ExtractCompositeWallQuantities1() { GS::Array<API_Guid> wallGuids; ACAPI_Element_GetElemList(API_WallID, &wallGuids, APIFilt_OnActFloor); char reportBuffer[4096]; BNZeroMemory(reportBuffer, sizeof(reportBuffer)); // Initialize reportBuffer with zeros char wallBuffer[512]; BNZeroMemory(wallBuffer, sizeof(wallBuffer)); // Initialize wallBuffer with zeros strcat(reportBuffer, "Composite Wall Quantities:\n"); for (const auto& wallGuid : wallGuids) { API_Quantities quantities; API_QuantitiesMask mask; BNZeroMemory(&mask, sizeof(mask)); // Initialize mask with zeros API_QuantityPar params; BNZeroMemory(&params, sizeof(params)); // Initialize params with zeros ACAPI_ELEMENT_COMPOSITES_QUANTITY_MASK_CLEAR(mask); // Clear the composites part of the mask ACAPI_ELEMENT_COMPOSITES_QUANTITY_MASK_SETFULL(mask); // Set the composites part of the mask to full params.minOpeningSize = EPS; GSErrCode err = ACAPI_Element_GetQuantities(wallGuid, &params, &quantities, &mask); if (err == NoError) { const GS::Array<API_CompositeQuantity>* compositeQuantities = quantities.composites; // Dereference the pointer if (compositeQuantities) { for (UInt32 i = 0; i < compositeQuantities->GetSize(); ++i) { const API_CompositeQuantity& compositeQuantity = (*compositeQuantities)[i]; double const wallVolume = compositeQuantity.volumes; double const wallProjectedArea = compositeQuantity.projectedArea; sprintf(wallBuffer, "Wall GUID: %s, Composite Index: %d, Volume: %.3lf, Projected Area: %.3lf\n", APIGuidToString(wallGuid).ToCStr().Get(), i, wallVolume, wallProjectedArea); strcat(reportBuffer, wallBuffer); } } else { strcat(reportBuffer, "No composite quantities available for wall GUID: "); strcat(reportBuffer, APIGuidToString(wallGuid).ToCStr().Get()); strcat(reportBuffer, "\n"); } } else { strcat(reportBuffer, "Failed to get quantities for wall GUID: "); strcat(reportBuffer, APIGuidToString(wallGuid).ToCStr().Get()); strcat(reportBuffer, "\n"); } } ACAPI_WriteReport(reportBuffer, true); }

Dear @BerndSchwarzenbacher ,

Please do you have any counsel relating to Composite Wall Quantities?

After this line:

API_Quantities quantities;

…add:

CompositeQuantityList composites; quantities.composites = &composites;

ACAPI_Element_GetQuantities won't populate this variable for you - leaving it as nullptr indicates you aren't interested in those quantities.

Then instead of this:

const GS::Array<API_CompositeQuantity>* compositeQuantities = quantities.composites;

…just use the existing composites variable.

Thank you @Ralph Wessel . I will try out what you advised. Even though I also tried ACAPI_Element_GetMoreQuantities() as described in the Documentation but still not successful. I try out your suggestion I hope all goes. Please, here is the extra code I tried but no result. Please, where do you think I made a mistake? Please I use Archicad 27 C++ API.

void CompositeWallQuantitiesExtraction() { API_Element element; GS::Array<API_CompositeQuantity> composites; GS::Array<API_Quantities> quantities; GS::Array<API_Guid> elemGuids; API_QuantitiesMask mask; API_QuantityPar params; ACAPI_Element_GetElemList(API_WallID, &elemGuids, APIFilt_OnActFloor); ACAPI_ELEMENT_COMPOSITES_QUANTITY_MASK_CLEAR(mask); ACAPI_ELEMENT_COMPOSITES_QUANTITY_MASK_SETFULL(mask); quantities.Push(API_Quantities()); quantities[0].composites = &composites; elemGuids.Push(element.header.guid); params.minOpeningSize = EPS; GSErrCode err = ACAPI_Element_GetMoreQuantities(&elemGuids, &params, &quantities, &mask); if (err != NoError) { ErrorBeep("ACAPI_Element_GetQuantities", err); return; } WriteReport("%s GUID:%s", ElemID_To_Name(API_WallID).ToCStr(CC_UTF8).Get(), APIGuidToString(element.header.guid).ToCStr().Get()); for (UInt32 i = 0; i < composites.GetSize(); i++) { API_Attribute attr; GS::UniString cFlags; GSErrCode err; attr = {}; attr.header.typeID = API_BuildingMaterialID; attr.header.index = composites[i].buildMatIndices; err = ACAPI_Attribute_Get(&attr); if (err == NoError) { if ((composites[i].flags & APISkin_Core) != 0) { cFlags.Assign("Core"); } if ((composites[i].flags & APISkin_Finish) != 0) { if (!cFlags.IsEmpty()) cFlags.Append("+"); cFlags.Append("Finish"); } } WriteReport(" composite: %s[%d] - volume: %lf - projected area: %lf - flag: %s", attr.header.name, composites[i].buildMatIndices, composites[i].volumes, composites[i].projectedArea, static_cast<const char*> (cFlags.ToCStr())); } }

Dear @Ralph Wessel , please your recommendations did not achieve the expected task. May be I did not understand and therefore still omitting something. Thank you for being there to help.

Try processing the quantities element by element like this:

void CompositeWallQuantitiesExtraction() { GS::Array<API_Guid> elemGuids; if ((ACAPI_Element_GetElemList(API_WallID, &elemGuids, APIFilt_OnActFloor) != NoError) || elemGuids.IsEmpty()) return; for (auto& guid : elemGuids ) { API_QuantityPar params{}; params.minOpeningSize = eps; GS::Array<API_CompositeQuantity> comps; API_Quantities quants; API_ElementQuantity elemQuants{}; GS::Array <API_ElemPartQuantity> elemPartQuantities; GS::Array <API_ElemPartCompositeQuantity> elemPartComposites; quants.elements = &elemQuants; quants.composites = &comps; quants.elemPartQuantities = &elemPartQuantities; quants.elemPartComposites = &elemPartComposites; API_QuantitiesMask mask; ACAPI_ELEMENT_QUANTITIES_MASK_SETFULL(mask); auto error = ACAPI_Element_GetQuantities(guid, &params, &quants, &mask); if (error != NoError) continue; for (auto& comp : comps) { //Process composite quants here } }

Thank you @Ralph Wessel . I will try you advice. I will get back to give you an update. Once again thank you.
