Dramatically slash your design revision time with parametric drawing. By defining persistent relationships between objects, parallel lines remain parallel and concentric circles remain centered, all automatically. And now, you can infer geometric constraints in real time—as you draw—eliminating the need to manually define all of your object relationships.
Sharing and reusing designs has never been easier thanks to robust PDF support within AutoCAD. With TrueType font support, import and underlay capabilities, and powerful publishing capabilities, AutoCAD helps facilitate clear communication when using PDF.
