How can You improve modeling speed using point clouds in Revit by 2x times?


When You think about Revit and point clouds, usually this combination does not bring the best emotions.

If You are working with a slightly larger project You know, that every time You use zoom in, zoom out or pan functions point cloud is rendering and You get delays which are frustrating. This has a significant impact on modeling time.

We decided to go totally different direction, and instead of loading heavy point cloud file, we generate dynamic images which will contain only desired information at the time.

With the help of the UNDET database, we generate dynamic images in Revit views and this allows us to have better visibility and almost totally eliminate lag which leads to a major improvement of modeling speed without changing any modeling habits and workflow.

So we did an experiment and compared modeling speed between standard Revit functionality and UNDET plugin.

We opened two new projects and started from scratch. So all this process contains loading up the project, inspecting it, and preparing for modeling. We modeled a small segment of the building which contained 78 elements such as windows (15), doors (10), internal walls (18) and external walls (35).

And the results were quite dramatic, using the same workflow, the same accuracy, and modeling the same elements in this specific project we were able to improve our modeling speed by up to 2x times.

It is worth mentioning that the first stage of preparing the project and generating a dynamic image took longer than simply adjusting point cloud using a clipping box, but the once-dynamic image was generated, we did not experience any performance drops and we had better visibility.

Another thing is that once you have generated a dynamic image it will stay in Your Revit file until You totally delete it, so it will load instantly any time You want.

So let’s talk about results.

As we mentioned before we modeled 78 elements which took us 28:02 minutes with standard Revit functionality from which 3:25 min was preparation for modeling and the same amount of elements took only 15:21 minutes with Undet from which 4:25 min was the preparation of modeling.

So if we would continue modeling the same building, the gap between modeling speed would increase even more. And if we would only look at pure modeling speed without all preparation process difference is 2,5 times and would increase if we would continue modeling elements at the same level.
