• INTRODUCTION
• Computer Aided Design refers to the designs that
  an engineer prepares for certain object using a
  computer. CAD models of mechanical designs help
  engineers to carry out analysis of the structure,
  improve the designs, improve productivity and
  decrease the cost of production. CAD software
  uses vector based graphics to represent drafts.
• The final object as per the computer aided
  design is produced by separate drafting of parts
  while assembling them on a later stage. Designer
  needs to specify other parameters for design.
• This includes materials used, processes that
  object needs to pass through, dimensions,
  allowances tolerances and more depending on
  software that he/she is using.

• USES OF CAD SOFTWARES
• CAD software is heavily used in the mechanical
  industries which play a pivotal role in
  manufacturing of each and every product.
  Mechanical design formed on a CAD software is
  used to study the object much in prior to the
  actual manufacturing which can help in optimizing
  the manufacturing process.
• Following are some of the uses of mechanical
  design softwares
• Mechanical designs can be directly uploaded to
  manufacturing machines like CNC machines and the
  product can be manufactured using Computer Aided
  Manufacturing Process.
• Mechanical designs can be used to analyse the
  product before actual manufacturing takes place
  and induce changes if necessary which is not
  possible after the production process starts.
• It can be fed to the 3D Printers for direct
  manufacturing after meshing it into layers of
  definite thickness.
• The software can also be used for Documentation
  purposes.
• CAD modelling can be used to mark material
  wastage regions which help in minimal material
  wastage.

• TYPES OF MECHANICAL DESIGN SOFTWARES
• There are different types of softwares for
  mechanical designs which require designer to come
  up with basic plan of the object differently.
• Following are two type of CAD softwares used for
  mechanical designs
• PARAMETRIC MODELLING This type allows the
  designer to induce changes into model anytime he
  wants. In this type of modelling, geometric and
  functional relationships in the model are
  preserved by software.
• DIRECT MODELLING This type of modelling does
  not have a history tree and model is directly
  converted into geometry. Designer does not need
  to change the original sketch to make changes.

• CAD SOFTWARES
• There are several softwares used for mechanical
  design but most common ones include Dassaults
  Catia, Dassaults Solidworks, AutoDesk AutoCad,
  TurboCad, AutoDesk Inventor etc. All these
  softwares have different interfaces and user
  friendliness.
• CONCLUSION
• CAD softwares used for mechanical designs have
  helped the production process to become more
  efficient by reducing wastage of material and
  using apt quality measures depending on the
  analysis done on CAD model. CAD softwares have
  different features integrated onto them which
  help in saving the crucial production time as
  well intern giving higher efficiency, larger
  profits and scalability.
