Set binary 3D data to library part

Martin Walter — Mon, 26 Sep 2022 21:00:59 GMT

For performance reasons I would like to add binary 3D data instead of scripted 3D data in the section API_Sect3DScript to a libraray part. The section API_Sect3DBinData seems to be what I need. But how can I use it?

You can update a libpart section using ACAPI_LibPart_UpdateSection.


API_LibPart			libPart = {};
API_LibPartSection 	section = {};
GSHandle			sectionHdl = nullptr;
libPart.typeID = APILib_ObjectID;
libpart.index = someLibPartIndex;
libPart.docu_UName = "MyLibPart";
section.sectType = API_Sect3DBinData;
section.subIdent = APISubIdent_Any;
err = ACAPI_LibPart_UpdateSection( libPart.index, &section, sect3DBinaryHandle, nullptr );

where sect3DBinaryHandle is a handle to your binary data.

Thanks! But is there some specification for the format of the 3D Binary section?
