AutoCAD tutorial: Extract attributes

Blocks can contain attributes, which are labels with properties. For example, you can use attributes to attach price and manufacturer information to a block of an office chair.

Once you have the attributes, you can extract them to a simple database and open that database in Microsoft Excel, for example, or insert it as a […]

Change the scale of blocks and hatches in tool palettes

Tool palettes are a great way to store blocks and hatches for easy access when needed. But if you have only one instance of each block or hatch, you may find that the scale isn’t right and the block or hatch comes in at the wrong size.

For example, you may need to change the […]

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 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 […]

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 […]

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, […]

Dynamic blocks: the white papers

I’ve written three white papers for Autodesk on Dynamic Blocks. Together, these three white papers provide a thorough overview of the dynamic block feature.

Part 1: Dynamic Block Overview and Quick-Start Tutorial. In this white paper I explain the concepts behind dynamic blocks and suggest some scenarios for their use. I display some sample dynamic […]

Toggling the display of grips within blocks

By default, when you select a block, AutoCAD displays only one grip, at the block’s base point. However, what if you want to grip edit the block from some other point in the block. You can do so by displaying the grips of all the objects in the block. Jack Foster sent in a great […]

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, […]

Divide up a polyline or spline

Ever need to place an object evenly along a polyline or spline? For example, you may want to divide a plat into equal sections or 40′ sections. For whatever reason, you can do this easily using the DIVIDE or MEASURE command.

These commands are especially useful when your object is a curvy polyline or spline […]

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 […]
