Setting the layer lineweight

Each layer uses a default lineweight. Lineweights determine the thickness of entities both on the screen and when printed.              

All new layers are assigned the DEFAULT lineweight, which is .25 millimeters or .01 inches. If you want a different lineweight assigned to a layer, you can easily change it using the Explorer. For example, you may want different lineweights on each layer of your drawing to show separate elements, such as walls, dimensions, structural steel, and electrical plans. Changing the lineweight assigned to a layer changes the lineweight of all entities drawn on that layer with the BYLAYER lineweight.

When you create new entities, its a good idea to assign the BYLAYER lineweight to any entities that you draw on that layer, unless you want to override the layer lineweight. progeCAD uses the BYLAYER lineweight as the default lineweight setting when you create entities (in the Drawing Settings dialog box).

You can change the default lineweight.
To change the DEFAULT lineweight, choose Tools > Drawing Settings, click the Display tab, click the Lineweights tab, and then select a new default.

To change the lineweight 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 Lineweight column for the layer you want to change.

   3   In the Lineweight list, select a new lineweight for the layer, then click OK.

Entities dont have to use the layers lineweight.
You can assign a specific lineweight to an entity, which overrides the layers lineweight setting. When you create a new entity, use the Tools > Drawing Settings > Entity Creation tab to change the current lineweight. For an existing entity, select the entity, right-click for the shortcut menu, and choose Properties. You can then modify the entitys lineweight using the Properties pane.
