Difference between 3D BIM & 2D Drafting Workflows

Both workflows will be compared at a functional level, including phase-by-phase comparisons. Upon completion, you will understand five major differences between 3D BIM & 2D drafting workflows.

Automated management of project documentation

2D drafting workflows produce DWG files with many dependent external reference definitions (XREFs). File-by-file management is typically used for these files, which are organized into sheet sets. A manual process is used to update documentation when design changes occur. A sheet set can be a very complex process with a high chance of errors if each view of each drawing is not exactly the same.

Databases always get updated automatically, as do the sheet sets that make up final drawing deliverables. All generated drawing views are automatically updated as soon as a change is made to the BIM model. A detailed review of the changed drawings is flagged, which assists in maintaining the integrity and accuracy of the sheet set.

Design captures using 3D massing and study models

Maquettes and hand sketches are usually used as visuals when selling a conceptual design to a client when using a 2D drafting-based workflow. In the past decade, most companies, including firms that use BIM, have created and rendered models using surface modeling tools like Trimble’s SketchUp. Designers can produce high-quality renderings, which are credible, by creating 3D study models.
