ACAPI_Element_Change Issue

4livesdragon — Mon, 19 Jun 2023 01:18:34 GMT

Hello everyone, I have encountered a very strange problem. I have two Archicad Pln files, the contents of which are the same except for a few object parameters. But when I change some object parameters, and call ACAPI_Element_Change at the end, one of the files can succeed, and the other file will always report an error at ACAPI_Element_Change? Does anyone know what the possible cause is and what are the key points when using API Element Change?

Thank you so much!

I think I found a possible reason. I found that in the unsuccessful file, ACAPI_Element_Create was not successfully called, nor did any errors occur, but after being called, no object was created. I wonder what are the conditions for ACAPI_Element_Create to be used successfully?

hello

without context it's hard to tell you, what's the problem, share more from the code but the ACAPI_Element_Create should look like this:

GSErrCode err = NoError; // element API_Element element; API_ElementMemo memo; Int32 addParNum; API_AddParType** addPars = nullptr; // libPart API_LibPart libPart; double a, b; Int32 nSystem; BNZeroMemory(&element, sizeof(API_Element)); BNZeroMemory(&memo, sizeof(API_ElementMemo)); element.header.type = API_ObjectID; err = ACAPI_Element_GetDefaults(&element, &memo); if (err != NoError) { ACAPI_DisposeElemMemoHdls(&memo); return err; } ACAPI_DisposeAddParHdl(&(memo.params)); // worth erase it memo.params = nullptr; // LibPart machinations BNClear(libPart); CHCopyC(objUNID, libPart.ownUnID); err = ACAPI_LibPart_Search(&libPart, false, false); if (libPart.location != nullptr) delete libPart.location; if (libPart.index == 0) { ACAPI_WriteReport("text", true); // GDL object not found! Please add them in Library Manager. ACAPI_DisposeElemMemoHdls(&memo); return err; } err = ACAPI_LibPart_GetParams(libPart.index, &a, &b, &addParNum, &addPars); if (err != NoError) { ACAPI_WriteReport("ACAPI_LibPart_GetParams[%ld]", false, err); return err; } // set basic parameters memo.params = addPars; element.object.libInd = libPart.index; element.object.angle = 0.0; element.object.level = 0.0; element.object.xRatio = 1.0; element.object.yRatio = 1.0; // for loop for change parameters for (Int32 ii = 0; ii < addParNum; ii++) { // change something in memo if (CHEqualCStrings((*memo.params)[ii].name, "someParameter")) { ((*memo.params)[ii].value.real) = 5.0; } } // for loop for change parameters ends // place something, .gsm in my case err = ACAPI_CallUndoableCommand("some text", [&]() -> GSErrCode { err = ACAPI_Element_Create(&element, &memo); if (err != NoError) { return err; } err = ACAPI_Goodies(APIAny_RunGDLParScriptID, &element.header); return err; }); if (err != NoError) { ACAPI_WriteReport("ACAPI_Element_Create failed", true); return err; }
