Support for 2-D and 3-D designs: Manual drafting is limited to 2-D designs.

You can have the dimensions as templates eliminating the need to start from scratch anytime you are doing a new design. With CAD, you can create standard templates to use in all your drawings that met industry standards.

You have to maintain a certain consistency in your drawings. Manual drawings are cumbersome when it comes to maintaining certain dimensions. Establish drafting standards: There various industry standards that architects and engineers have to maintain in their drawings.Coding systems save time, boost productivity by preventing the need to re-create designs again. This means when you want a particular design all you have to do is pull it out from its related classification. Classification and coding systems: Designers have the ability to grope similar items together through a system of coding and classifications.CAD software often has numerous standard templates that save you time of making a design from scratch. They can also make further changes to the design.

CAD drawings can be saved and shared among different designers. Another designer finds it hard to make changes without starting from scratch.

Ability to Save and modify drawings: Manual drawings pose various challenges when it comes to saving them.

You can also rotate objects and view them in different perspectives. The best part is you can draw everything to scale. CAD gives you unlimited drawing abilities. Instead of a system of pencils and rulers you have tools to create lines, circles, points, polygons and so much more.

Drawing tools: What really stands out for CAD unlike manual drawings are the tools used.
