E-book: AutoCAD Block Best Practices

We draw repetitively when using AutoCAD. If we manage the drawing elements as reusable contents, it will increase our productivity significantly. Not only can we draw faster, we can add information to our blocks. Which allows us to generate useful reports. This is what Edwins e-book entitled AutoCAD Block Best Practices is all about.
