Block

In the context of AutoCAD, block is simply a collection of objects that act as a single object and they can be used in a drawing repetitively.
Advantage of an AutoCAD Block.

  • We can insert block again and again, saving time. In fact, we can insert block into other drawings as well.
  • A block uses less electronic space than individual objects, so our drawing file is smaller.
  • By updating a block’s definition, we can update all the blocks in the drawing at once.
  • Note: If we try to insert a block from another drawing that has the same name as a block in the current drawing, the block definition in the current drawing will be used instead.

    The block basically needs to follow two steps
  • Create New Block
  • Insert Block or Insert Existing Block

    Create New Block

    Draw an object > Press B (for block) > Give the block name > Select objects > Pick Point > Ok 

Insert Block or Insert Existing Block
When we insert a block reference, we specify its location, scale, and rotation.
 Press I (for Insert Block) > Current drawing , Recent and Other drawing 
If Current drawing > Select block > Double click on block > insert in drawing
If Recent ( Here will be the most recent block ) > Select block > Double click on block > insert in drawing
If Other drawing > Give the path for block ( click on three dots  in top right corner for path) > Select block > Double click on block > insert in drawing  

   Attribute

   Attributes can be added to make block definitions more informative. Attribute definitions are a great         way of storing text information as part of blocks.
   For example, we can add an attribute to a MCCB block of a drawing indicating its manufacturer’s name,     size or description. we can add visible as well as invisible attribute values to the blocks.  

 How To Add Attribute In Block

Draw object > Add attribute > Create block
