I'm trying to invoke the AutoCAD Import command via the Design Automation API. This works fine from accoreconsole.exe locally, and while the Design Automation API accepts the Import command without error, it proceeds to the next command without importing anything.
In the excerpt of a Design Automation API output log below I'm invoking the Import command both directly from the generated script file and via SendStringToExecute via my plug-in. In the latter case I've pulled the full local file path.
