2D to 3D CAD Conversion
Conversion of 2D CAD Drawings to 3D


A number of professional designers prefer to make 2d drafts and then convert the 2D to 3D CAD drawings later with CAD softwares like AutoCAD, Catia, Revit and Solidworks because making a 3D drawing is an arduous task indeed and requires expertise of high order.

Reason for Converting 2D to 3D CAD Drawings:

  • 3D drawings are much easier to visualize
  • 3D models can be viewed from different angles. This nullifies the problem of hidden features in 2D drafts
  • 3D models are much less clumsier and hence make the dimensions and other necessary details very easy to understand
  • Special features like fillets and chambers are very clearly depicted by 3D models
  • 3D models enable cut-away viewing for internal features of a model
  • 2D drafts can very easily be extracted from 3D drawings but not the other way round

For simple projects having uniform depth, such 2D to 3D CAD drawing conversions is easy. The 2D drawing is simply extruded or padded depending on the software in use. However, if the project is multi-layered and complicated, the designer usually has to start the 3D model from scratch using the 2D drafts for reference.

2D to 3D CAD Drawings Conversion is used for Multiple Purposes like:

  • Architectural Drawings
  • Manufacturing Drawings
  • BIM drawings and related Plumbing and HVAC Drawings
  • Drawings for the Defense Department
  • Drawings for the Automobiles, Aerospace and Marine industries

In today’s construction scenario, a lot of attention must be given to every little detail as the slightest mistake might result in dire consequence. It is extremely important to choose the firm you employ very wisely. A little research into the background of the firm you intend to hire will go a long way in ensuring that your investment is a healthy one indeed.
