Is it possible to create wall programmatically with C# while creating wall manually in editor?

[simongido1]

Hello, I am trying to create walls programmatically using C#. I tried using both custom IExternalEventHandler and UIControlledApplication Idling handler. Unfortunately, Idling nor custom event is executed when I am not editing my walls using the editor. This is the code I use to create walls. It works correctly when I am not modifying walls.

transaction.Start("create wall");

Wall wall = Wall.Create(document, line, levelId, false);
App.ThisApp.World.SetEntityElementID(wallData.Entity, wall.Id);

transaction.Commit();

Should implement IUpdater to respond to changes in the document with further changes.

I tought updater will respond only if I finish wall, the problem is, my walls come from external source over internet

Your question is a little confusing, and I guess you want to execute some code when you are inside the Revit Wall command when you are on the state to draw some walls.

If that's the case probably the Idling and IExternalEventHandler never gonna fires.

Idling only fires when Revit is not busy, when you execute some command Revit stops firing Idling until the command ends.

IExternalEventHandler is similar, gonna fire when an Idling event happens.

IUpdater is possible to trigger some code when you create a Wall.

See yaa!
