# Redefine Block [GstarCAD 2019](Help%20System/GSTARCAD/2019/Index.md) → [What's new](Help%20System/GSTARCAD/2019/What's%20new/(What's%20new).md) ## **Redefine Block** Now design center offers a quick way to update instances of block. Redefining a block allows you to overwrite each block instance without changing the block name, all while keeping the original block's position. Alternatively, if you just copy a newer version of a block into your active drawing, the block will not update – it will instead inherent the active drawing's block definition. By redefining a block, there is no need for deleting, purging, and copying.  --- Xi'an Gstarsoft Ltd ## Other versions with matching text [GstarCAD 2020](Help%20System/GSTARCAD/2020/What's%20new/Redefine%20Block.md)
