- 用Block Editor修改現有的Block，完成後所有Block Instances自動更新。
這些方法遠比複製物件快，也可省略重新建立的工夫。利用進階功能Dynamic Block，更可以加入幾何和尺寸限制，簡化製作library的過程，其參數更能快速為報告提供所需資訊。 一間工程公司若能認真去為工程師建立一個Block Library，除提高生產力外，更能確立一個標準，而不會突然出現因誰貪快製作出不一致的圖則。
AutoCAD block holds important role in productivity. However, it’s often overlooked by many users. When you want to change a door, you may want to:
- Replace the model with other model. You can do it easily by replace that door with other door type from your library.
- Modify the block in block editor. All block instances will be updated when you finish.
This is much more faster than copying objects, as well as to spare the time required to redraw your common objects and annotations. By using advanced function, Dynamic Block, you can apply geometric constraint and dimensional constraint that you can use in blocks, enabling simplification of your library drawing and process, and allowing easy extract of information for reports.
An engineering firm should seriously develop a block library for all of the engineers, so that on top of productivity, you can make your drawings consistent.
