ToolsFramework: add UInteractiveCommand and UInteractiveCommandArguments types, base classes for 'interactive commands' which are intended to be used for atomic actions, ie stateless, no user interaction, etc ModelingComponents: add UGeometrySelectionEditCommand/Arguments, this is a UInteractiveCommand that uses a FGeometrySelection as an argument add UGeometrySelectionManager::CanExecuteSelectionCommand() and ExecuteSelectionCommand() MeshModelingTools: add UDeleteGeometrySelectionCommand, deletes selected mesh geometry by converting input selection to list of triangles ModelingToolsEditorMode: add Delete command to ModelingMode and UI. ModelingToolsEditorMode currently is keeping active command set alive via new UModelingToolsEditorMode::ModelingModeCommands member. #rb none #preflight 62d195b9a66919b6701d89a8 [CL 21113757 by Ryan Schmidt in ue5-main branch]
