A pocket-size version of the full-featured AutoCAD reference tool and training aid, called The CadCARD Slidechart, is available. CadCARD Jr features a reversible insert for calculating drawing scales, scale factors, inverse multipliers, and text heights for commonly used sheet sizes. The original, CadCARD Slidechart and CadCARD Jr. are reference tools for use with AutoCAD. They are intended to provide designers, engineers, and drafters with an easy-to-use aid in many of the day-to-day CAD tasks that would otherwise have them reaching for a calculator or the software's user guides. The CadCARD Slidechart and CadCARD Jr. are available at www.cadcard.com.
