I have been taking a lot of photos lately to test different photogrammetry software, and sometimes I feel that the results is better than it should have been since I usually shoot from my hip.
One of my favorite programs is Memento from Autodesk that is a really great software. Memento is in Beta mode but has the tools you need to generate a mesh/pointcloud from your pictures. The interface is really great and it is easy to use.
It has some issues with Z-direction and scaling when you export it, but hopefully they will fix this bug shortly. It is also frustrating that it is not possible to import the mesh into Revit. Therefor you need to export the model as a pointcloud to import it to Revit, and that is a pity. It would have been great to use the mesh to create sun study for instance, or to create the surroundings to your project. This is not a Memento problem. It is a Revit problem.
Remember to import your cool models into Sketchfab so you can show them to your colleges or embed them into your homepage (if they support it…) 🙂
One of the questions I get a lot, is how to set the coordinate system in a project and how to import the pointcloud at the correct position.
There are several ways of doing this, and it is up to you to find your best way. The video gives an introduction of the consepts:
- importing a DWG that has world coordinates
- setting up two coordinate system (one with real world coordinates and one internal)
- importing pointcloud that has the same 0 point as the internal coordinate system
Sometimes new technology needs to mature before it is efficient or useful to use in the daily work. And as an architect, I always need to balance the time and effort to play with new tools that may be useful in the future.
Photogrammetry on the other hand is not a new technology anymore. But since new software makes the process much smoother, and the prices for drones has been dropping, there is a lot of new potential with this technology.
That is why I have made a couple of case studies lately, to understand the limitation and possibilities for a real life project. My first experiment is with the DJI Phantom 2 drone, and I wanted to see what kind of accuracy I got from the mesh and the pointcloud from the photogrammetry.
I was rather impressed to see the results if you take in consideration that the drone only took 31 photos, but maybe it is not accurate enough to use it in the design phase. But then again, how accurate do you actually need the surroundings to be? When you import it to Revit, the pointcloud may give value as an reference.
Special thanks to Geomatikk Survey for the excellent drone service.
I am going to work on a project together with an architect that is located far away from where I am located, so I have been trying to find a good solution how to work together on the same Revit model without too much hassel.
I hoped that I could avoid setting up a server, and wanted therefor to try use the A360 service. I soon understood that I needed the Autodesk A360 Collaboration for Revit subscription, but when I tried to buy it I was forwarded to the European Autodesk site. Here I did not have an option for subscribing this service.
I talked to the Autodesk staff and understood that it was only available in North America and he did not know when it was going to be released outside North America.
I have been working at Dark Architects since 2006, but I felt it now was time to experience other types of projects and opportunities. I therefore decided to start my own office called Hel Ved Arkitektur AS.
«Hel Ved» litterally means solid wood, but it is also an expression that has a deeper understanding. In Norway we use the expression for describing something, or someone, that is «rock solid» and «genuine».
These values are values I wish my company will be associated with, both regarding architecture and management.
I notice that I encounters different challenges now that I am a small company regarding technology and digital design compared to my previous workplace. I am looking forward to post these experience on this blog.
Just imagine the power of combining a lasercutter and gingerbread. I have talked about it many times, and it was time to «walk the talk».
Step 1: Roll’it out
Step 2: Lazzzer it up
Step 3: Reviewing the results
Step 4: Assembly
Despite the smell of burned gingerbread, the results of my first lasercutted gingerbread is promising. Next year I will take it to the next level so stay tuned. Merry Christmas!!
I have just returned from an excellent trip to Shanghai where I attended my first Autodesk Revit Gunslinger event. We were in total 16 Revit enthusiasts from around the world and we tested new Revit features for four days. The event was superbly organized by the Autodesk team and we had a great time!
