Is custom .NETCore running application inside AutoCAD or Civil3D?

How can I tell if my custom .NET application is running inside plain AutoCAD or Civil 3D?

I'm not civil, so I can't test this . .

Crude, but may suit the situation.
Identify a System Variable unique to Civil3D

Check it's value.

Something like :

global using CadApp = Autodesk.AutoCAD.ApplicationServices.Application; global using Exception = System.Exception; [assembly: CommandClass(typeof(ProductInfoTest.Commands))] namespace ProductInfoTest { public class Commands { [CommandMethod("Test")] public static void Test() { var ed = CadApp.DocumentManager.MdiActiveDocument.Editor; try { //var cmd = (string)CadApp.GetSystemVariable("ACADVER"); //var cmd = CadApp.GetSystemVariable("UCSICON"); var cmd = CadApp.GetSystemVariable("PPOINT"); ed.WriteMessage($"\nVariable .Test : {cmd}\n"); } catch(Exception ex) { ed.WriteMessage($"\nError: {ex.Message}\n"); } } } }

Have you tried checking the PRODUCT system variable?

Hi Tony,

I wasn't sure about that because you can start "Civil 3D as AutoCAD" using a different profile ( if I remember correctly )

. . . though it makes sense that the "Product" variable would change, so that would be simpler.
