Set the Current Linetype
All objects are created using the current linetype, which is displayed in the Linetype control on the Properties toolbar.
You can also set the current linetype with the Linetype control.
If the current linetype is set to BYLAYER, objects are created with the linetype assigned to the current layer.
If the current linetype is set to BYBLOCK, objects are created using the CONTINUOUS linetype until the objects are grouped into a block. When the block is inserted into the drawing, those objects acquire the current linetype setting.
If you do not want the current linetype to be the linetype assigned to the current layer, you can specify a different linetype explicitly.
The program does not display the linetype of certain objects: text, points, viewports, hatches, and blocks.
