Again, this may seem basic, but it happens more than one would think. Knowing the difference between XYZ and NEZ when communicating with the rest of the team regarding survey control is critical. Once the model is dragged or rotated into place manually, a valuable benefit of 3D scanning has been lost.

Surveyors can use both their coordinate system and the project team’s UCS if they know how to utilize and export data on an alternate UCS. This task will not be a problem with solid communication across the project team and an agreed-upon solution. Surveyors and engineers generally dislike the use of 0, 0, 0 coordinate values, which is opposite members of the construction community, who generally prefer a close origin. This is not a problem if everyone coordinates the scanning effort and has an understanding of what will be delivered. At this juncture, the point cloud needs to be incorporated into the existing model or vice-versa. Too often a project is already underway when the need for 3D scanning arises. My favorite is the workset option “visible in all views,” helpful if turned off for large, sluggish, linked models.įigure 1: Some of the workset ideas and options available What Coordinate Systems Will Be Used? Revit 2017 and updated 2016 now have the “unload for me” option however it can still be helpful to manipulate linked models including point clouds via worksets. When opening the model, the user can specify what worksets (point clouds) should be turned off/on when opening a large model. This enables additional visual and project stability support. Speed things up with Worksetsįor additional control, it is helpful to place each point cloud on its own workset. Also consider segmenting the project floor by floor to manage file sizes in multi-level projects. Less data loaded allows for more fluid movement and far less frustration. The use of “Regions” in ReCap will create layers within the point cloud that can then be toggled in Autodesk® Revit®.

In the event that a hardware upgrade is not feasible, arrangements should be made up-stream for another project participant or consultant to convert the data into an Autodesk model. Hardware problems can be avoided by checking this item off the list up front. Again, this may seem fundamental, but it is a common problem that leads to frustration. Many scanning programs will not open more than one view without an Open GL card on board. Most use NVIDIA, but if not, the card should support Open Graphics Language (Open GL). All participants loading a point cloud of medium size or larger need some horsepower on their desk.

One simply cannot function on a computer with 4GB of RAM and an integrated graphics card when working with point cloud data. Municipal employees are usually 2-3 years behind on their computer hardware (and that’s being generous). There are many scenarios that can inhibit the use of a 30GB file, including the time and bandwidth needed to transfer large files or improper graphics drivers, which can be troublesome when loading or viewing data. Unfortunately, project teams are still met with the lack-of-power dilemma. It may be perplexing to some folks that in 2017, design teams would have insufficient computing horsepower to effectively utilize point cloud data. Let’s look at the most basic items to check off the list prior to diving into a point cloud. The most basic 3D scanning applications can become counterproductive simply because not everyone understands what the data is, or how to use it for optimal productivity. Many people know what 3D scanning is, but not everyone is as versed in working with point clouds downstream.

It can also add layers of complexity, confusion, and frustration if not executed properly on a project. Back April 11th, 2017 Cool, a Point Cloud… Now What?ģD Scanning has become commonplace on many projects, and can save hours of field verification.
