Setting the layer linetype    

Each layer uses a default linetype (a repeating pattern of dashes, dots, or blank spaces). Linetype determines the appearance of entities both on the screen and when printed.    

Its a good idea to assign the BYLAYER linetype to any entities that you draw on that layer. progeCAD uses the BYLAYER linetype as the default linetype setting for Entity Creation (in the Drawing Settings dialog box).

Using the Explorer, you can set or change the linetype assigned to a layer. With the direct-editing feature, you can click on the linetype you want to change, and then select a new linetype from the dialog box that appears. Changing the linetype assigned to a layer changes the linetype of all entities drawn on that layer with the BYLAYER linetype.

Only those linetypes already set in the drawing can be assigned to layers. For more information about setting additional linetypes, see Working with linetypes.

To change the linetype assigned to one or more layers

   1   Do one of the following to choose Explore Layers ():    

    On the ribbon, choose Home > Explore Layers (in Layers) or choose Tools > Layers (in Explorer).

    On the menu, choose Format > Explore Layers or choose Tools > Explorer > Explore Layers.

    On the Explorer toolbar, click the Explore Layers tool.

    Type explayers and then press Enter.

   2   Click in the Linetype column for the layer you want to change.

   3   In the Linetype dialog box, select a new linetype for the layer, or click Browse to select your linetype file.

Entities dont have to use the layers linetype.
You can also assign a specific linetype to an entity, which overrides the layers linetype setting. When you create a new entity, use the Tools > Explorer > Explore Linetypes command to change the current linetype through the Explorer. For an existing entity, select the entity, right-click for the shortcut menu, and choose Properties. You can then modify the entitys linetype using the Properties pane.
