Steps to take when creating dynamic blocks

Dynamic block is a very useful feature in CAD, and there are a few steps users can take to create high-quality dynamic blocks with efficiency.

1.Planning

It is necessary to plan the dynamic block before actually creating it. For example, the appearance of the dynamic block, the functions of the dynamic block, what parameters and action are used to be fully functional, etc.

2. Draw objects

3. Add parameters and actions

4. Test the dynamic block

5. Save and exit the block editor

How to create a simple dynamic block using parameters and actions.

Let’s take an easy example to look at the steps for creating dynamic blocks

1.Draw a rectangular as the basic object, then enter B command, enter a name and specify base point to define the rectangular as block.

2. Double-click the block to enter block editor.

3. Click Linear in the Block Authoring Palettes, and snap two rectangular points as start point and end point to create linear parameters as prompted and drag the parameters to proper positions, shown as below,

Linear parameter is similar to linear dimension. The default names for linear parameters are “DISTANCE 1” or “DISTANCE 2”, if there are multiple linear parameters in the drawing, we can open Properties Panel using CTRL +1 or rename parameters in the right-click menu, for example, we can change its name to “Width”, shown as below,

4. Click Stretch in the Actions tab of Block Authoring Palettes, when the system prompts us to “Select Parameters”, just select the parameter we just defined,

5. Specify a parameter point according to prompts, the point will be stretched , shown as below,

The above are some basic steps for creating dynamic blocks. Creating blocks is not that hard, although involving parameters or actions may make it seem hard at first.
