[Source issue details](../../Source%20Issues.md). <!-- /help-structure:notice --> ## **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. ![Missing source image: pic/Redefine Block.jpg](Help%20System/GSTARCAD/2021/assets/missing-source-image.svg) --- Gstarsoft Co.Ltd. ## Other versions with matching text [GstarCAD 2019](Help%20System/GSTARCAD/2019/User%20Guide/What's%20new%20in%20GstarCAD%202019/Redefine%20Block.md) · [GstarCAD 2020](Help%20System/GSTARCAD/2020/User%20Guide/Additional%20Pages/Redefine%20Block.md)
