Point Clouds in 2014

[nealmac1978]

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.

One trick I've seen done before is to load it into a separate revit model, then link the revit model in. That may help.
Can I inquire in to what your workstation specs are. We've done a few projects with rather large point clouds and haven't had any major problems or slow downs.

Thanks for the suggestion. I'll give that a try and see does it help.

My specs are:
Windows 7 professional 64 bit
Intel i7 2860QM CPU @2.5GHz
16GB RAM
Nvidia Quadro 4000M

The only downer I'd say with your system is the clock speed of the chip.
The other thing we've done is moved away from workstation graphics cards.
Basic gaming cards work great.

Yeah, well to be fair Revit doesn't actually utilise the graphics card as much as some other applications. I'm definitely going to be looking at the GeForce series on my next machine. Preferably something like the GTX780 Ti. The reason for this, is that we use Lumion quite a bit, and it seems to struggle with the Quadro card. Lumion recommends GeForce all the way.

Sorry, gone off-topic now.

I have no idea what version is it, but we built a box just to run lumion. I think we dropped $1000 on that graphics card. I believe it is a GeForce, no idea on model number. All I know is that it's smoking fast comparatively.
