How to switch to 3d window by ACAPI?

sxs — Thu, 29 May 2025 11:56:10 GMT

Hi,everyone:

GSErrCode err = ACAPI_Sight_SelectSight (nullptr, &origSight); if (err != NoError) { ErrorBeep ("Cannot switch to the 3D sight", err); return err; }

I try this to switch to the 3d window, but it does not work.

Call ACAPI_Database_ChangeCurrentDatabase passing APIWind_3DModelID as the API_DatabaseInfo.typeID

This API still has no effect, but the return value is NoError. Is it related to my ArchiCad currently running DEMO status?

{ API_WindowInfo windowInfo; API_DatabaseInfo origDB, planDB; API_Element element; GS::Array<API_Guid> elemList; GSErrCode err; BNZeroMemory(&planDB, sizeof(API_DatabaseInfo)); planDB.typeID = APIWind_3DModelID; //ACAPI_Database(APIDb_GetCurrentDatabaseID, &origDB, nullptr); ACAPI_Database_ChangeCurrentDatabase(&planDB); // BNZeroMemory(&windowInfo, sizeof(API_WindowInfo)); windowInfo.typeID = APIWind_3DModelID; windowInfo.databaseUnId = planDB.databaseUnId; err = ACAPI_Window_ChangeWindow(&windowInfo); }

this can work.

You can use also ACAPI_View_GoToView()

When you say it has no effect, do you mean you don't see the view come to the front? If so, this isn't what ACAPI_Database_ChangeCurrentDatabase does. It makes the 3D window the current database for all following API commands that concern a specific database, e.g. ACAPI_View_Rebuild

If you simply want to bring the view to the front, use ACAPI_Window_ChangeWindow, but I don't think that's what you want to do in the context of a notification handler
