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 […]

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 large. […]

Here’s how it works:

Type xplode on the command line. At the Select objects: prompt, select one or more blocks. If you […]

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

Instead, many people create block libraries, putting […]

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 […]

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 the objects, […]

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 want to write.
