Do Not Expect AcRx::kLoadDwgMsg and AcRx::kUnloadDwgMsg in ObjectDBX Modules

Level

Requirement

Applies to

ObjectDBX modules

AutoCAD sends these messages whenever the user opens or closes databases for editing, but other host applications do not necessarily do so. Therefore, an ObjectDBX extension that has a non-null response to these messages will fail when used with host applications other than AutoCAD.
