Blocks A Block is a collection of entities bound together as a single  entity. After creating  a Block, we can insert it whenever we need it in a drawing. When you use the MakeBlock command, the symbol is recognized in the current drawing only. The MakeBlock command write a symbol to an external drawing file for use in any drawing. Click the MakeBlock icon on the Draw toolbar. The Block Definition dialog box is displayed. Name: Enter name. Description: Enter description. Units: Select Millimeters. Block entities: Click the Select in graphics area icon. Specify entities>> enter To insert a block Click Insert, Block from the Main menu. The Insert Block dialog box is displayed. The Insert Block dialog box provides the ability to select created symbols. Select the created block and specify the position in drawing where it can be inserted. Position X: Position Y: Click OK. Explode a Block DraftSight  provides  the  ability  to  explode  a  Block  into  its  compon

Working with Layers Working  with  Layers  is  analogous  to  drawing  manually  using  Layers  of  see-through  media.   Parts  or portions  -  these might be functional portions, such as Construction Lines,  of one complete drawing are drawn on different 'media' that, imposed on top of one another, form the entire drawing. Layers are useful in  separating  entities,  such  as  parts  or  sub-assemblies,  or  structural  components,  such  as  pipe  sizes  or building materials. They also serve to separate elements such as Construction Lines, Centerlines, Outlines, and Dimensions, or items  that are to be placed in a group, such as foliage in an architectural drawing. When you use Layers, you have a clearer construction of the drawing and better control over the drawing. Layer 0: The Default Layer The default Layer is called 0. It is automatically generated by  DraftSight when a new drawing is created. This is your active Layer which is shown, un-suppressed and  unl

COPY COPY is the command is used to create one or more copies of selected objects.  The copies of the object can be drawn by selecting the copy tool from modify toolbar.
