Auto-Created sections but Viewpoint not appearing in the Navigator

Hi everyone,

I’m trying to automate the creation of cut planes in front of ~200 doors, so that each door has its own section.

I compute each door’s position and then create an API_CutPlaneType element for the cut line and marker. This part works. The marker shows in plan. But no section is added to the Navigator, and the marker is locked so I can’t manually convert it into a real section viewpoint.

Here’s my (messy) code : (Devikit 25)

#include "APIEnvir.h" #include "ACAPinc.h" #include <cmath> #pragma execution_character_set("utf-8") static void WriteReport(const GS::UniString& message) { ACAPI_WriteReport(message.ToCStr().Get(), false); } static GSErrCode ValidateDoors(void) { GSErrCode err = NoError; GS::Array<API_Guid> doorGuids; err = ACAPI_Element_GetElemList(API_DoorID, &doorGuids); if (err != NoError) { WriteReport("Erreur lors de la récupération des GUIDs des portes."); return err; } WriteReport("Nombre de portes trouvées : " + GS::UniString::Printf("%d", doorGuids.GetSize())); Int32 doorIndex = 0; for (const auto& doorGuid : doorGuids) { API_Element doorElem{}, wallElem{}; BNZeroMemory(&doorElem, sizeof(API_Element)); BNZeroMemory(&wallElem, sizeof(API_Element)); doorElem.header.guid = doorGuid; if (ACAPI_Element_Get(&doorElem) != NoError) { WriteReport("Erreur lors de la récupération de la porte."); continue; } wallElem.header.guid = doorElem.door.owner; if (ACAPI_Element_Get(&wallElem) != NoError) { WriteReport("Erreur lors de la récupération du mur parent."); continue; } // Points début/fin du mur API_Coord beg = wallElem.wall.begC; API_Coord end = wallElem.wall.endC; // Vecteur unitaire du mur API_Vector wallVec = {end.x - beg.x, end.y - beg.y}; double vecLength = sqrt(wallVec.x * wallVec.x + wallVec.y * wallVec.y); if (vecLength < 1e-9) { WriteReport("Longueur mur invalide."); continue; } API_Vector wallUnitVec = {wallVec.x / vecLength, wallVec.y / vecLength}; // Position porte double objLoc = doorElem.door.objLoc; API_Coord doorPos = { beg.x + wallUnitVec.x * objLoc, beg.y + wallUnitVec.y * objLoc }; // Normale (perp. mur) API_Vector normVec = {-wallUnitVec.y, wallUnitVec.x}; // Préparation de la coupe API_Element cutPlaneElem{}; API_ElementMemo cutPlaneMemo{}; API_SubElement cutPlaneMarker{}; BNZeroMemory(&cutPlaneElem, sizeof(API_Element));

} // Libération ACAPI_DisposeElemMemoHdls(&cutPlaneMemo); ACAPI_DisposeElemMemoHdls(&cutPlaneMarker.memo); } WriteReport("Validation des portes terminée."); return NoError; } static GSErrCode __ACENV_CALL MenuCommandHandler(const API_MenuParams* menuParams) { WriteReport("Menu sélectionné : Validation des portes + création de coupes."); return ValidateDoors(); } GSErrCode __ACDLL_CALL RegisterInterface(void) { return ACAPI_Register_Menu(32500, 32501, MenuCode_UserDef, MenuFlag_Default); } API_AddonType __ACDLL_CALL CheckEnvironment(API_EnvirParams* envir) { envir->addOnInfo.description = "Valider les données des portes et créer des coupes"; return APIAddon_Normal; } GSErrCode __ACDLL_CALL Initialize(void) { GSErrCode err = NoError; err = ACAPI_Install_MenuHandler(32500, MenuCommandHandler); if (err != NoError) { WriteReport("Erreur lors de l'installation du gestionnaire de menu."); } return err; } GSErrCode __ACDLL_CALL FreeData(void) { return NoError; }

I must be missing something. The line is drawn, but I don’t see any new section in the Navigator. Has anyone successfully done this? Any help or guidance would be greatly appreciated!

Thanks!
