About Graphic Properties
Most of the attributes common to all object types can be set and changed in the Properties Bar and in the Graphic Atributes panel. Properties that are shared among most object types are: layer, pen color, fill color, pen line types, start and end markers, pen weight, shadow.
To set the properties for new items, make sure no object is selected and then use the controls on the bar or in the panel. To edit the properties of an object, select it and then change the corresponding values.
Graphic properties specific of some objects, such as extension lines of dimensions or hatches and fill color of walls, are managed through their Settings window.
