A short exposition on the development of multidisciplinary 3D models!

The concept of developing 3D virtual models for the purpose of executing a building project was not there for long instead it is a new trend that have been optimized by AEC professionals for streamlining building activities or methods.  Until BIM’s presence in the industry CAD software served the purpose of developing models. But modeling process was soon dominated by BIM software such as Revit in context of construction industry. Huge amount of information and data is needed by BIM modelers for developing multidiscipline 3D models. In other words design data or information is required by the modelers of service providing company for the execution of modeling services.

Be it architectural, structural or MEP model, they are all developed on the basis of the design developed by relevant engineers. On the other hand multidiscipline 3D models are created on the basis of design created by architect, structural engineer or MEP engineers. So the information related to the design is always present in the CAD drawings which are developed by the technicians at the time of drafting process. In other words execution of architectural, structural and MEP drafting is very crucial prior to the execution of modeling services since relevant drafting documents are used for reference purpose during modeling.

So it is important for the modelers of the service providing company that they have all the necessary drafting documents with them while they develop 3D models. While working on a Revit modeling project CAD files are generally linked by the modelers in their current project for extracting the information. For example while making 3D floor plans in Revit it is important for modelers to have all the CAD floor plan drawings with them which when linked to the project help in obtaining information.


So in this way more than one CAD file is linked by the modelers to their current project for developing effective models. It’s not just the CAD drawings that are used for getting information however thing like PDF and other external sources are optimized by BIM modelers for developing precise 3D models in BIM software.

A brief account on BIM’s expansion over the years

Building Information Modeling has a dramatic history when it comes to its expansion in the landscapes of AEC industry over the years. BIM which is also known as Virtual Design and Construction has a dominant presence in AEC industry because of the fact that is has the potential to realize project outcomes and can control them significantly as per requirement. In short design and construction professionals can attain superior control over project outcomes by analyzing multidiscipline models. Well, Building Information Modeling evolved as a concept some four decades ago but it was not practiced by AEC professionals in the industry at that time. For approximately ten years since it first appeared in the journal, the term ‘BIM’ used to be seen only in research papers. BIM as a technology and a process started to be implemented in construction projects some thirty years ago. So once AEC professionals started using BIM in construction they never looked back to their sluggish performanc...

Determine the size of your family according to your project requirement in Revit!

Revit is considered the best choice by architects, engineers, BIM modelers and technicians working in AEC industry for creating families. Families are basically used by BIM modelers while executing Revit modeling services. That makes Revit and Revit modeling services an integral part of construction project execution. Family size matters a lot when it comes to designing a building. In Revit technicians have the luxury to control family size as per the requirement of their project. If in case a smaller size door is required for one of the rooms in the building it can be easily created by using the Family Editor tool of Revit. Revit Family Editor has vital features for developing custom families. The Family size can be controlled by BIM modelers by assigning required dimensions for the family.   In other words the geometry of the family can be easily controlled by assigning parameters in Revit. Take an example of door family; it’s up to Revit modelers what dimensions they want ...

Structural drawings: What is the role of Revit structure and Tekla Structure in their development?

Among all kinds of construction drawings it is really difficult to develop structural drawings as they are of highly complex nature. For developing strong and durable structural framework, the first step is to develop high quality structural drawings which can effectively describe structural design.  For the comprehensive understanding of structural design numerous kinds of technical drawings which may include detailed sketches, plans and working drawings etc have to be developed by drafters and detailers on the instructions of structural engineers.   In this blog I would like to focus on the development of Steel fabrication drawings and erection drawings which are created by steel detailers when they execute Structural Steel Detailing Services with the support of Revit structure or Tekla Structure.    Both Revit structure and Tekla structure are most widely used software packages which are utilized by steel detailers for the development of d...
