AutoCAD tips and tricks booklet is an annual ritual for Lynn Allen as the AutoCAD evangelist. She always published the booklet for each release for years. I remember the first time I have the printed booklet when AutoCAD is still delivered physically. Today, the booklet is only available in PDF format.
The AutoCAD 2018 tips and tricks booklet is now available for download. You can download the booklet here.
Remember: you need to fill the form before you download it.
