Blockify automatically creates a block definition and replaces all matching sets of entities with block references throughout your entire drawing. You can reduce DWG file size up to 90% by using Blockify to find repetitive geometry and convert it into block references.
Parametric Blockify is even more powerful, using a parameterised set of entities as input, and finding any geometry of the same form which fits the range of the parameters of the original block.
With the ability to also create blocks automatically from copies of geometry which have been tweaked slightly, it enables the power of blocks to be realised even more effectively.
Other CAD software relies on the user to create individual blocks by hand, which is far more timeconsuming.
