The Basepoint option of the INSERT command

When you insert a block, a Basepoint option appears with the [...]

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 strechable, 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 helped [...]

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.

In “Tutorial: Create attributes,” I mention that you can use [...]
