Point Cloud Density Display issue

BalajiHTI — Sun, 17 Jul 2016 06:24:20 GMT

Dear All,

Greetings!

I would like to ask a question regarding the display of point cloud.

Below is two snapshots of an *.RCS Point Cloud Laser Scan linked in a Revit Project.

The image in the left and the right are of the same point cloud.

Right is what we see. The one with better appearance.

Left is what our contractor's see. Its a bit less dense and 'line'y so to speak.

If zoomed in the point cloud looks like in the image above.

We don't know what could be the possible reason. The contractors are doing As-Built documentation, i.e. modifying an existing Model based on point cloud data. Since they can't clearly see the point cloud as we see, they are unable to exactly correct the models.

We and the contractors, both are using NVidia Graphics Card. Please tell us the possible reasons, so we can check if anything is rectifiable.

Thanks in advance.

UPDATE: Just figured out the Revit Structure 2014 displays the linked RCS point cloud with higher density. So is there any possible fix for architecture or MEP? Like a Service Pack update is available?

Were those two screen captures taken from the same computer? I don't think there is a difference in how 2 versions of Revit of the same year display a point cloud. But it is very possible that your computer and your contractor's computer are different in terms of hardware.

Dear @Alfredo_Medina

The imaged attached in the question is from two different computers. But the second image I attached in a self reply, is from own system Revit ARC and Revit STR Side by side. I am attaching it again for confirmation.

RESOLVED! Contractor installed some Windows Update and it fixed the Graphics Driver issue. Now point clouds are fine.
