AutoCAD 2D TutorialControl the Color and Linetype of Blocks 19.3The objects in an inserted block can retain their original properties, can inheritproperties from the layer on which they are inserted, or can inherit the propertiesset as current in the drawing.You have three choices for how the color, linetype, and lineweight properties ofobjects are treated when a block reference is inserted.-Objects in the block do not inherit color, linetype, and lineweightproperties from the current settings. The properties of objects inthe block do not change regardless of the current settings.-For this choice, it is recommended that you set the color,linetype, and lineweight properties individually for each object inthe block definition: do not use BYBLOCK or BYLAYER color,linetype, and lineweight settings when creating these objects.-Objects in the block inherit color, linetype, and lineweightproperties from the color, linetype, and lineweight assigned to thecurrent layer only.-For this choice, before you create objects to be included in theblock definition, set the current layer to 0, and set the currentcolor, linetype, and lineweight to BYLAYER.-Objects inherit color, linetype, and lineweight properties from thecurrent color, linetype, and lineweight that you have set explicitly,that is, that you have set to override the color, linetype, orlineweight assigned to the current layer. If you have not explicitlyset them, then these properties are inherited from the color,linetype, and lineweight assigned to the current layer.-For this choice, before you create objects to be included in theblock definition, set the current color or linetype to BYBLOCK.- 169 -
