Dynamic blocks in AutoCAD–When and why?

I’ve written posts about how to create specific types of dynamic blocks and about some of their features, but I’ve never explained when and why you would use a dynamic block.

If you have a block library that contains variations on an object or component and you insert them at various scales and rotations angles, […]

Chain dynamic blocks in AutoCAD

Dynamic blocks, introduced in AutoCAD 2006, are very powerful, but sometimes they can get complicated. One of the more involved features of dynamic blocks is chaining. In this tip, I try to make chaining easy.

Sometimes, you want one action to execute a second action at the same time. If the relationship between the two […]

Stretch to 3 sizes Flip left/right Flip in/out

This tutorial is updated for AutoCAD 2010 and 2011. Follow these steps:

Working with Blocks: The BASE command, the Basepoint option, and the Basepoint parameter

Blocks and basepoints go hand-in-hand. Knowing how to work with basepoints can make your life much easier. It’s so frustrating to insert a block and have it disappear into outer space because the basepoint is in the wrong location!

The Basepoint option of the INSERT command

When you insert a block, a Basepoint option appears […]

Create a rectangle with an adjustable corner, Part 2: Using a dynamic block

In a previous post, “Create a rectangle with a flexible corner,” I showed how to create a rectangle whose upper-right corner is stretchable, creating a flexible rectangle that doesn’t lose its shape. In this post, I show how to do the same with a dynamic block.

Thanks to Joel, whose comment to the earlier post […]

Tutorial: Use fields to automatically label dynamic blocks

You can use fields (AutoCAD 2005 and later) to create automatic labels that provide information about objects.

I’ve covered aspects of this topic before. In “Tutorial: Display the area of an enclosed figure,” I show how to use fields to create a label that displays an area.

In “Tutorial: Create attributes,” I mention that you […]

Flip objects with dynamic blocks

You can create dynamic blocks that you can easily flip after you insert them. This is great for doors which may open from the left or right, or open inward or outward. Dynamic blocks were introduced in AutoCAD 2006.

Follow these steps to create a door that flips both ways:

Start with a door block, […]

Align a block to other objects with a dynamic block Alignment parameter

If you’d like to be able to quickly snap a block aligned or perpendicular to another object, a quick, helpful use for dynamic blocks is the Alignment parameter. Unlike most other parameters, you don’t need to specify an action.

The Alignment parameter is easy to create. Make the block and open the Block Editor (the […]
