BLOCKIFY command
Converts identical set of entities (2D or 3D) to block references.

Description
Searches the drawing for an identical set of entities (2D or 3D) and replaces them with block references.
Method
There are four methods to use the BLOCKIFY command:
- Convert 2D and 3D entities to blocks.
- Convert equally shaped solids to blocks.
- Find collections.
- Match existing blocks.
If a selection set is active when launching the command, the current settings of the BLOCKIFYMODE and BLOCKIFYTOLERANCE system variables are used for running the command.
If no selection set is active when launching the command, the Command Context panel opens:

- Blockifymode settings
- Tolerance
- Blockifymode settings
- Shows all the settings available in BLOCKIFYMODE system variable with their current state and lets you modify them:
- Tolerance
- Allows you to modify the current value of the BLOCKIFYTOLERANCE system variable that specifies the relative tolerance for determining whether two entities are equal.
Options within the command
- match Equal solids
- Searches the drawing (or the selection) for equally shaped solids and replaces them with newly created block definitions. In case a solid matches an existing block definition, the replacing block reference points to that block definition.
- Specify block name or <ENTER to use default name>
-
Specify a block name or use the default name. If you choose to use the default name, block definitions with names like Block, Block1, Block2 etc. are created.
Note: If BLOCKIFY is used on BIM entities, it checks the BIM Name property of all equal-shaped BIM classified solids and tries to find the longest common substring to use it as the name of the block definitions.
- find Collections
-
Identifies collections and eventually nested blocks are created. This option opens the Find Collections panel.
Note:- This option only works on block references. If the model also contains other entities, these will not be taken into consideration.
- With a large number of input entities, calculating all possible collections can take a long time. Press the Esc key to cancel the calculation at any time, and choose from the collections found so far.
- match existing Blocks
- Searches the drawing (or the selection) for 2D geometry matching existing block definitions.
- selection options (?)
- Lets you choose one of the listed methods to add entities to the selection set.
