I'm having serious issues with Revit crawling at a snail's pace whenever I bring a point cloud into it. Can Anyone help me? I've done all the usual setting up plan views and sections with minimal view range to minimise background noise, but still no joy.1: I've read that I need to break the point cloud file into smaller pieces. If this is true, how do I go about doing it? It's in RCP format.2: I've used Recap to get my RCS files (3 in total) into RCP format, as I believe this is the correct way to do it in 2014.3: What is "indexing" files? I'm unser the impression that it's the process of making a point cloud "workable" in Revit. I may be wrong on this.I think what I need, is a proper step by step tutorial on how to bring the point cloud file into Revit, in the correct manner, in the correct format that doesn't slow Revit down.Thanks.

Point clouds are huge and will always slow you down.  You need to place these in their own workset (normally off in all views) and only load it when needed.

Thanks.

But wouldn't that be very labourious? If I'm trying to model an entire building from a point cloud, I'd need to have it switched on most of the time.

Perhaps you need to look at this:

The link redirected me and after logging in, I could also not find this add-in.  There is some useful information here.:

When we are working with a large point cloud we put in on a workest as WWHub explained but also under visability graphics you have an option to turn off certain scan points.  So we generally turn off all of the scan points that we do not need at the moment and just leave on the ones that we need for the area we are currently drawing.

Thanks.

Unfortunately when I expand my point cloud tree, I only have 3 parts. I think it needs to be broken down into more parts. See attached:

I don't know how your pointcloud was created so it's hard to say but from that I would assume that only 3 scans were used to create the pointcloud, so those 3 are your only options to turn on/off

Ah. That's what I was afraid of. Thanks anyway.
