Creating AutoCAD Dynamic Blocks


Good dynamic blocks must be simple to incorporate into other drawings, straightforward to use, and free of glitches that can frustrate the experience. To create high quality blocks, use the following steps:

  1. Have a plan for the contents of the block. That is, you should know how it should appear and in what way it will be used. Deciding in advance which components are active, and in what way they will modify the block will make the following steps easier.
  2. Using the drawing area, Block Editor contextual tab, or Block editor, to create all the common elements. If you will be using visibility states, create them after the common elements, and then add the additional components for each visibility state.
  3. Following your plan from step one, add the parameters and actions in assending order of inflence, with all the parameters added before any of the actions. In other orders, if a parameter and action will modify other parameters and actions, it should not be the first created. (It is possible to modify earlier parameters and actions, if necessary.)
    1. Add Parameters
    2. Add Actions
  4. Define how the block will be manipulated through custom grips and custom properties.
  5. Test the Block
