Welcome to AutoCAD’s Class. With this suite of tools, you will be able to produce high quality designs in less time, via the significant improvements in precision and flexibility while working in both 2D sketches and 3D modeling. Developed based on the feedback from actual users, AutoCAD includes the features that designers and engineers need in order to do their best work. Richer design context and more intelligent tools clear the way to faster, more precise design and documentation. The new smart dimensioning feature automatically creates appropriate measurements based on the type of objects you select.
