Clash Detection Using Autodesk Navisworks Manage

Testing the Clash Detection Feature of Navisworks Manage to compare it to other platforms.

Chapter II of the Quick Comparison between Clash Detection capabilities of different software platforms. I am on the process of running a quick comparison of the different tools out there to run Automated Clash Detection. The first one I tried was Tekla BIM Sight. Here is a quick video on the same process done with Autodesk Navisworks Manage 2014.

My quick thoughts on how it works are these:

• On the upside, almost as easy to run as with Tekla BIMSight, maybe a but less intuitive when you run it for the first time.
• Also positive. Good visualization of the clashes with ghosting of the other elements to perfectly see the two elements in conflict.
• Not sure still if good or bad: With the same files and tolerances used for Tekla BIM Sight's test it reported only 241 Clashes. (that is 139 less than Tekla BIMSight). WIll have to check the reason for this but it is a very big difference and needs to be anayised.
• On the downside: The price of the Software.

Since the new version of Navis was released last week for download, I installed it and gave a try to the same feature on Navisworks Manage 2015. Everything seems to work as good as in 2014, not any changes seen at first sight. Video below.
More to come soon on other platforms (As many as I can have access too).Any thoughts on this? Please comment

After analyzing part of the questionnaires of my master thesis I created this table showing the answers to the question "Which software package do you or your colleagues use regularly?" There where a total of 93 completed questionnaires from several locations and from a varied type of stakeholders, so the sample can be considered quite representative. I was surprised though by the high percentage of respondents who answered that they or their colleagues used Revit regularly. Here maybe is where the sample has some flaws, and people applying BIM concepts were more prone to answer the questionnaires than those who don't. Hard to guess. In any case, here is the table, take your own conclusions.

Autodesk Navisworks Freedom: Clash Detection Viewer

Download the Free Viewer for Navisworks.
Català - Castellano - Deutsch
I was working recently in a project where collision detection was needed to ensure that the work done by architects, structural engineers and MEP Engineers was fitting with each other. The program chosen to do this was Autodesk Navisworks.

As with almost all Autodesk Products, the license price is quite expensive (~$10,000). Luckily, only the consultant in charge of the clash and collision detection had to assume this license price. All other consultants could visualise the collisions detected using the free viewer, Navisworks Freedom.

Autodesk navisworks Freedom is the free counterpart to the expensive Autodesk Navisworks Manage. It allows to visualise the 3D Model and to see the collision markups created with Navisworks Mananage. For us, it was enough to have Navisworks Freedom installed in all relevant workstations and have only the Clash Detection Constultant do his job and to send us the file so each spacialty (Architecture, Structre, MEP...) could follow up on the markups and solve the issues.

You can download Navisworks Freedom here
