DWG Viewer - Switch between model and sheets

Status
titleOBJ-C
Status
colourYellow
titleC++

The DWG Viewer uses a native method -(void)AddSheetButtonsTo:(UIStackView*)sheets to get all available sheets of the drawing. All available sheets are stored as a UIButton inside a UIStackView. The button is linked with a command expression that is executed when tapped. The command _SHEET_CONTROL handles the layout switch.
