Why do we convert BIM to CAD Drawings?
It is common to convert Building Information Modelling (BIM) to Computer-Aided Design (CAD) during the construction phase of a project. There are many reasons as to why there is a need for BIM to CAD conversion. A BIM model is typically used for the purpose of visualisation and clash detections. However, there is a need for the BIM model to be converted to CAD drawings for the purpose of Authority submissions and construction professionals to use on-site.
Authorities are still requiring submissions to be done in CAD formats as not all professionals in the AEC industry are familiar with BIM models. They may be able to navigate the models but they are not equipped with the knowledge to use the BIM models for reviewing the design details. Hence, the 2D CAD drawings are still needed to be submitted. In addition, many construction professionals are still not trained in using BIM hence the need for CAD drawings. BIM has the ability to allow models to be converted to 2D plans automatically with the use of the software functions.
