Point Clouds in Bimsync | Catenda Help Center

This feature provides the ability to visualise Pointcloud datasets (PC) inside Bimsync.

You can preview individual PC inside the Document area, and you can combine them in our 3D viewer. Download a sample file from here.

Also, you can view simultaneously PC and IFC models inside Bimsync 3D viewer.

Bimsync allows you to upload 2 formats for PC data:

You will upload the files as every other file in the Document section.

The 3D button is blue, meaning the PC is displayed in the viewer.
The magnifying glass icon allows you to center the view on this PC.
Finally, the settings buttons is here to allow further adjustments.

Individual PC settings:

PC are available from various sources, and for that reason, they will need some specific adjustments.

Attribute: allows you to choose to display either RGBA (colours) or Intensity. It's very useful when the points doesn't include colours.
Opacity: when models are displayed together with PC, it can be necessary to dime the PC data to have a better understanding of the viewpoint.
Point size: it can be set either to Adaptive (default), or Fixed size. The slider below helps you make the final setting. There is no rule for the correct value, it will depend on the data you upload (size of the dataset, point density, type of scan, etc...). Our advice: load the PC, and after a brief moment, when enough points are displayed, start to adjust the settings if necessary.
