Every element (axis, column, wall, beam, line, circle, etc.) you draw in the drawing area is called an object. There are two methods for operations such as deleting, moving, rotating, changing the properties of objects. First one is that the object is selected after entering the command. Second one is that the command is entered after the object is selected. In both methods, the selected object changes color according to the customizable selected object color. When properties are changed in selected objects, only the changed information is updated on the objects.
There are various methods for selecting objects in the ideCAD.
