So if I understand correctly, the "cleanup" region is still in your project?
If so, that would most likely be the cause of the slowness. These regions tend to be very complex, and the recommended workflow is to delete this region (choosing the option to delete the region and included points) and then optimize the project.
I deleted "Manual Cleaning" region I created, along with the points in the region. I then attempted to save the project. Following the click of the "Save" button, Recap crashed and I was greeted with the Autodesk "Send Error Report" dialog. You can find the details with the following error report identifier:
I'm going to go out on a limb here and say that the recommended workflow should not be "recommended" if this is the typical result.
The export issue around project export that was reported here has been moved to a separate thread, in order to not confuse it with the subject of this one.
Thanks for providing the CER number. It looks like this crash has only happened to a couple of users in the past, so it is certainly not the norm.
For your cleaned region, did you perform automatic cleanup and then add additional points to the region? If we know more about what is in this region, we might be able to help sort it out.
To answer your question, I had either window or fence selected points in the cloud and moved them to the "Manual Cleaning" region. I did this for points distributed around the cloud that were either objects I didn't want to keep, stray points, or noise. I had one other region that was called "Lvl 1 - Floor". I didn't use the new cleanup tool at all. I had tried it in a previous iteration of the project, but that file became corrupted when I tried to save it.
There was nothing particularly special about the region that I deleted, or the points that were contained in it, at least not by my estimation.
I can certainly send you the project if you are interested.
As far as this "not being the norm", I hope you will forgive me if I don't find that particularly comforting considering the amount of time that I have wasted trying to use Recap to do what it is supposed to be able to do.
True, my apologies for the time you've sunk into something that should just work. You should receive a box.com shared folder invitation shortly, where you can upload the project (RCP file and Support folder) if you're willing to let us take a look.
Also, if you end up with a corrupted file at some point, as you mentioned below, there are generally up to three project backup files corresponding to the last three saves within the Support folder. They have the extension ".rcp.bak". Placing one outside of the Support folder and renaming the extension to ".rcp" will effectively restore it.
Something that helps is setting the far view to something reasonable. It begins at 3,000 feet. I have reduced it to 500 (as that is the limits of my project), and the viewing is a little faster. It's under Home, Settings (gear box), General "far plane:". I also just tried setting the units to three decimal places... Didn't help that much.
I have an i7 quad core processor, with 8gb Nvidia M4000 video card. I have a point cloud generated from 200+ photographs. I do find it taxing that once I create about 5 regions, I lose significant performance.
Have there been any updates/improvements made to this issue? I'm using regions in a ~15GB point cloud right now that, like many others in this thread, was working just fine before I started assigning any points to regions. I noticed that the actual .rcp file ballooned to something like 10x larger while the Support folder size stayed the same, which I guess makes sense. But it seemed odd that classifying points into regions would make normal operations such as panning and orbiting so much slower. Why would the region metadata even be referenced during operations that have nothing to do with regions?
It's a shame because even with tools like PointSense and EdgeWise, I would still prefer to use the point geometry for documentation rather than waste time creating Revit elements, and Revit 2017's ability to read ReCap regions made me hopeful we could do this more going forward.
as far as I know, the trouble is more related to "selectioning" then with regions. The more you select points by hand (to change them to another region) the more these "selections" have to be stored in the RCP.
I use the "import Regions from CSV file" procedure, and I have no issues with performance. My problem is that there was a limit of only 80 Regions.
In any case, always use the most recent version of Recap. Things have impoved a lot since 2016.
@Patrick_Aps_9121 Thank you very much for your reply.
@travis.rothbloomMY5UY I am sorry you are experiencing this issue. This reason why navigation is affected by region is that the points you see on the screen are only part of the point cloud data. When you navigate the project, more points are loading from files to refine the detail. And region effects have to be applied to the new points too.
@Patrick_Aps_9121 has suggested a great way to improve the performance of selections and regions. In addition to this, we have proposed some small tips in another relevant post:
Repost it here:
1. Use more regions instead of putting a lot of selections into one region. The performance majorly depends on how many selections you have made instead of how many regions you have. Splitting big regions into smaller ones will help to improve the performance especially when you want to lock / hide that region, i.e. make regions to be locked / hidden contain fewer selections.
2. Although plane selection is very useful to select points, it scarifies some performance since plane bound can be as big as project bound, which spans more area compared with using rectangle selection with limited bounding box.
3. Keeping your selection as tight as possible to include only the points you want to select also helps to improve performance.
4. Use clip tool to aid your editing process when you want to temporary hide something.
And add one more:
If you are using deletion to clean the data, you can use optimize tool in "Save as" to permanently remove the deleted points and this will also improve the following editing process.
Hope this helps.
