Test on Running an IFC Based Clash Detection using Revit

I tried this and it is not a pleasant process.
Català - Castellano - Deutsch
So on the series of quick testing clash detection features using IFC files, I decided to give it a try with Revit since it has an Interference Check function. What I learned from the test is that it is not the right software to do this (specially having free alternatives like Tekla BIMSight). Anyways here is the quick video on the process and below a short description of the steps. If you want to skip this one, feel free, summary is, I wouldn't use Revit to do this.

So this is the quick summary of the process. Since Revit can not link IFCs, you actually need to do the following:

1. Open ifc file A
2. Save As Revit File A
3. Open IFC File B
4. Link Revit File A in it
5. Run the interference check

On top of this, the default visualization features of the interference check in Revit are awful (you basically have a hard time finding the elements visually. So as I said, nice try but to me this is a no go.

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

Clash Detection Using Tekla BIM Sight

Testing the Clash Detection Feature of Tekla BIM Sight to compare it to other platforms.

I am on the process of running a quick comparison of the different tools out there to run Automated Clash Detection. THe firs one I tried is Tekla BIM Sight. Here is a quick video on the process which is quite simple.

My quick thoughts on how it works are these:

• On the upside, it is extremely easy to run a test, very intuitive and you can do it after 1 minute of installing the software. Plus TeklaBIMSight is free.
• On the downside: The visualization of the clashes is not very good. When you click on a "Conflict" the program zooms to it, but it does not ghost other elements or highlight enough the involved elements for a good visualization.

So, this are my thoughts on the process of comparing this process on different platforms. I understand I might have overlooked some settings to allow me to better visualize the conflicts / clashes in the model, but the idea is to compare the software packaes as you find them after installing.
