Understanding Revit Pipe Sizes and Elevations

An important aspect of using Revit MEP is the ability to place pipes for various piping needs of a building project.  When placing pipes, the user specifies the pipe size and elevation, but those have some caveats which may not be readily apparent or what the user assumes.  There are pipe settings and parameters for diameter, nominal diameter, outside diameter, inside diameter, invert elevation, and justifications, which all interact with each other to determine the actual location of a pipe.

It can be a bit daunting understanding how the various pipe size parameters interact with elevation distances and dimensions.  Hopefully, this article will help make it less daunting.

Tekla BIMsight Continues to Improve

I have previously written about a software named Tekla BIMsight which is a good option for collision detection for building models. (Click here for article)  After I first encountered this program and wrote the article about it in February of 2011, Tekla has continued to improve the software.  The great part about this software is that it is still FREE.  It is still  a very viable option for designers who need collision detection capability, but can’t afford software like Navisworks Manage.

Tekla has a new update out for BIMsight and I still believe that it is a decent program and should be investigated to see if it meets your needs.  The current (new) version is 1.9.

Public Entities Requiring BIM and have Standards

The AEC industry is seeing more clients requiring Building Information Modeling (BIM) on projects.  Some clients have very detailed standards and expectations for the BIM process, and some clients say that they want BIM but have not idea what they really desire or how to get BIM.  And then, there are clients that fall somewhere between those two types.  Many clients (especially in the private sector) that have BIM standards in place have not publicized their standards, but will provide it to the design/construction team for specific projects.  However, there are public entitites that have established BIM standards and have posted those standards on the internet and are accessible to anyone with internet access.  Since it is nice to reference those BIM standards, I thought that I would list various public entities which have BIM standards that you can reference.

Clearance Zones in Revit Families – Part 2

My previous article discussed the importance of creating Clearance Zones inside Revit familes for equipment and items that need clearances for ADA, safety, air movement, or other reasons.  While that article also discussed the behind the scenes set up to get Clearance Zones into a Revit family, this article finishes the process of creating the actual Clearance Zone.

Clearance Zones in Revit Families – Part 1

Many pieces of equipment in a building have clearance zones that are required around the equipment for a variety of reasons.  It may be a drinking fountain that requires ADA clearance, an electrical panel that requires code clearance in front it, or mechanical equipment that requires air movement or access clearance around it.  For whatever the reason, it is good to build that clearance zone into the Revit family so that it be used for interference detection through Revit or Navisworks.

Free 3D Model Review Software Has Update

In February 2011, I reviewed a new free product on the market for 3D model review named Tekla BIMsight by Tekla, Inc. (Read review)   Tekla has recently released the new Tekla BIMsight version 1.3, and the big point is that it is still a free product.

As I mentioned in my first article on the BIMsight software, this is a basic clash detection software that allows you to bring several different 3-D models together for project collaboration and collision detection.  While it is not a robust software, it performs clash detection that can meet the needs of many people and that I believe warrants consideration.  It is a straight forward software that is not difficult in learning to use and also has a decent forum support system that is easily accessible from within BIMsight.

Update to Free 3D Model Review Software

In February 2011, I reviewed a new free beta product on the market for 3D model review named Tekla BIMsight by Tekla, Inc. (Read review)   Tekla has just released the new Tekla BIMsight version 1.2, and it is no longer considered a beta software.  The big point is that it is still a free product and Tekla stated in a webcast for bloggers that it will continue to be free for the foreseeable future.
