Blocks are compound objects that are commonly used for symbols, parts, detail views, and title blocks.

Using blocks provides the following advantages:

• You can ensure uniformity between identical copies of furniture, fixtures, parts, symbols, and title blocks in drawings.
• You can insert, rotate, scale, move, and copy blocks much faster than operating on selections of individual geometric objects.
• If you edit or redefine a block definition, all block references in that drawing are updated automatically.
• You can include data such as part numbers, costs, service dates, and performance values to blocks. The data is stored in special objects called block attributes.
• You can reduce the file size of a drawing by inserting multiple block references instead of duplicating object geometry.

You can create drawing files for the purpose of inserting them into other drawings as blocks. Individual drawing files are easy to create and manage as the source of block definitions.

• Specify the name of the block
• Specify the base point of the drawing By default, the WCS (world coordinate system) origin (0,0,0) is used as the base point for drawing files inserted as blocks. You can pick by mouse to reset the base point.
• Specify the objects to make block.

Sets the effect of block creation on objects used to create a block.

• Convert to block. Converts the selected object or objects to a block in the current drawing after saving them as a file.
• Retain. Retains the selected objects in the current drawing after saving them as a file.
• Delete. Deletes the selected objects from the current drawing after saving them as a file.
