Set All Object Properties to BYLAYER in AutoCAD 2008

Sometimes you’ll run into a drawing where the object properties are set to a specific value, like a certain color or linetype, instead ofBYLAYER.

Additional promptsallow you to choose if you want to change object properties that are currently set to BYBLOCK and/or objects within blocks.

If the objects are moved so that they no longer intersect, the break will disappear and ifthey are moved back the break will automatically return to the proper location. The Manual option enables you to specify start and end point of the break. You can use the Restore option to remove all...
