AutoCAD Tutorial: Create a dynamic block of a door

Dynamic blocks are an amazing feature, but they can be complicated. This tutorial will teach you many techniques that you can use in your own blocks. The door will do the following:

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

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

Quickly find out how many insertions of a block are in your AutoCAD drawing

Do you sometimes want to know how many times you inserted the widget block in your drawing? Here’s a quick way:

Display the Properties palette (Ctrl+1).
Click the Quick Select button at the upper-right corner of the Properties palette.
In the Quick Select dialog box, from the Object Type drop-down list, choose Block Reference. If you choose one [...]

How to control what you see by clipping xrefs and blocks

You can attach other drawings to the current drawing to facilitate the drawing process. For example, you can attach a floor plan to a drawing of an electrical layout to make sure that you put the outlets in the right location. These other drawings are called external references, or xrefs.

Sometimes, xrefs can be [...]

Select all instances of a block

Follow these steps:

Open the Properties palette.
Click the Quick Select button to open the Quick Select dialog box.

XPlode a block

You can use the EXPLODE command to break up the block into its components, but you don’t have control over layer, color, or linetype. The XPLODE command gives you that control.

Here’s how it works:

Type xplode on the command line.

At the Select objects: prompt, select one or more blocks.

If you select more than one [...]

Write blocks to save them as separate files

When you create a block in a drawing, you should think if it will be useful in other drawings.

You can access that block from other drawings using the DesignCenter, but you’ll probably need to remember where the block was, in order to find it.

Instead, many people create block libraries, putting several blocks [...]

Substitute one block for another

One of the advantages of blocks is that you can substitute one for another. Why would you do that?

Your organization switches to a different part
You need to create more than one version of a drawing, each with a different part

If you use blocks for this purpose, think how much faster it would be to [...]

Redefining a block without losing your insertion point

Have you ever had the experience of redefining a block and finding that the insertion point is way off? Or perhaps the block just seemed to disappear and you couldn’t figure out where it went! It turns out that how you redefine the block makes a difference.

After you have exploded and changed [...]

Select a block before a writeblock or edit

If you want to writeblock a block (use the WBLOCK command to save the block as a separate drawing file), normally, you’d start the WBLOCK command first. But then you have to choose the Block option in the Write Block dialog box and use the drop-down list to choose the block you [...]

All the ways to open a drawing

There are lots of ways to open a drawing and sometimes you may not think of the quickest way right away. Here’s my list:

The OPEN command. This is the obvious one, of course. Click the Open button on the Standard toolbar. (In 2009, click Open on the Quick Start toolbar.) Or type open [...]
