What is CAD?

Computer-aided design, or CAD, is the use of computers to help in creating, modifying, analyzing, or optimizing a design. It covers a wide variety of design tools that are utilized by a number of industry professionals such as architects, game designers, artists, manufacturers, and engineers.

Traditionally CAD systems were limited to only having 2D capabilities. Similar to drawing on a flat sheet of paper — you can only design or draw objects using basic views. Modern CAD software allows us to draw in 3D and deliver in either 2 or 3D.

CAD systems immensely aid their users by performing thousands of complex geometrical calculations without anyone having to think about it. As a result, these calculations are able to read by other programs to manufacture a product from CNC machines to injection molding.

CAD design modifies, analyzes, or optimizes the data acquired from scanning. Traditional design allowed a user to take the 2D version views and “pull” them out of the page to make it into a 3D object on the screen. This process is 10x faster with 3D scan data.

Data from rendering creates a virtual object that can have all of the same properties of a physical object — from its material, weight to its size, optical and physical properties.

CAD allows us to create assemblies of parts to see how they fit together. In addition, you can also test how they will react to force, fluidity, or motion

What kind of Software Do We Use?

Tangent Solutions uses the most recent version of Solidworks but your CAD design data can be delivered in any format that is required. File formats include:

  • XT
  • STEP
  • IGS
