Procedure of Mechanical CAD Drafting

Posted by on

Mechanical CAD drafting is a procedure, which imparts the engineers, design developers and clients with the capability to visualize the mechanical projects in three-dimensional aspects.

With the advancement in the CAD tools and techniques, the drawings are not only limited to paper drawings. Instead, highly integrated designs are now developed using the various designing tools to exhibit the projects in a photo-realistic way before the start of the practical construction.

The drawings developed by the mechanical CAD drafting process are not only detailed and accurate but can also be designed in a faster way, thereby saving a significant amount of time.

The professionals known as the drafters may have to design different types of mechanical components such as jigs, fixtures, clamps, conveyor belts and much more simple and complex designs. Developing sketches of the mechanical components is one of the fundamental duties of the drafters.

Advantages of Mechanical CAD Drafting are as follows:

  • Any modification in the designs gets automatically updated in the whole design thereby saving a lot of time.
  • Enhances clarity of communication related to mechanical drafts between the designers and clients.
  • Helps in managing the whole design data with ease and accuracy.
  • Helps in a more efficient digital prototyping process.

Sketches are also known as free hand drawings and a drafter can generate different idea options of the designs. Sketching can be developed in two procedures, which are known as the orthographic method and the isometric method.

In the orthographic procedure, the two dimensional aspects of the project are demonstrated. However, by the use of the isometric method, the drawing can be viewed from multiple dimensions and angles.

Once the approximate or rough sketches are developed, proper dimensions are then added to them using the computer software. The whole process of mechanical CAD drafting can be automated by using highly efficient drawing and drafting software tools such as AutoCAD and Inventor.

The software tools are comprised of functionalities, which can effectively reduce the time taken for the drafting of the mechanical assemblies and reduces the chances of any type of re-work by developing the accurate dimensions.
