Faro As built Modeler point cloud size

david.bruni — Tue, 15 Mar 2022 02:24:50 GMT

I've just started using point clouds in autocad and I was wondering if anyone knows if there's a limit to the As built Modeler point cloud size? I've got a point cloud that's 1,800,000,000 (+=/-) points. One billion, eight hundred million. Is that too much for autocad to handle?

My problem is that once I load the point cloud and start switching UCS, zooming and panning around, doing 3D orbit, after 10-15 minutes, they start acting strange. 3D orbit especially. I've got ORBITAUTOTARGET set to 0 but it acts like it's not. I try to 3D orbit and it goes off the screen. I'm using the middle mouse button to zoom, pan and 3D orbit.

It get's so bad that it becomes impossible to zoom in, add some center lines, or anything. I'll try to zoom window and it won't even zoom on the crosshairs. Sometimes clicking the quicksave button makes the view jump off screen. Sometimes scrolling the wheel won't zoom unless I press and hold it. 3D orbit is the worse. It becomes unusable.

I don't know if this is an autocad problem or as built modeler problem.

My computer is an alienware R11

CPU i7-10700KF @ 3.8 GHz

64 gigs of DDR4 ram

Nvidia Geforce RTX 3080 with 10 gigs of ram

Yeah, I'm using my gaming computer to run autocad. Any help would be appreciated. I've tried most of the fixes from the knowledge base and from googling around the internet.

Hi @david.bruni,

Great question. That is indeed quite a large point cloud.

AutoCAD based products, including Civil 3D, have a maximum limit of 25,000,000 points, using the 2015 RCP, RCS formats. This can be set via the POINTCLOUDPOINTMAX command.

For legacy (Pre-2015) RCP, RCS formats, the maximum limit is 15,000,000 points which can be set via the POINTCLOUDPOINTMAXLEGACY command.

All the best,

What's the extension of your 'original' Faro point cloud?

E57? las? laz? fls?

I don't know?

Does turning DRAGMODE off help?

If it's something that gets worse the longer you work, it's likely overloading the Undo history with all those positions of all those points, etc. I suggest clearing that out as often as you dare. I have a little command called DUH [= Dump Undo History] for the purpose:

;; DumpUndoHistory.lsp (defun C:DUH () (setvar 'cmdecho 0) (command "_.undo" "_control" "_none" "_.undo" "") (setvar 'cmdecho 1) (prompt "\nDumped Undo History.") (princ) )

I started with .fls files, I ran them through recap and created an .rcp. The .rcp file is what I have loaded in acad right now.

I forgot to say in my original post that I'm using autocad 2022 and as built modeler 2021, if that matters.

I'll give dragmode a try. It was set to auto. I turned it off. And I will give your "DUH" file a try. However, just this morning the 3dorbit started acting like it was set to "1", but it's set to "0", drove me crazy for a while, then fixed itself and went back to normal. It's really irritating when you can't orbit correctly. I appreciate the help.

Duplicate post.

@david.bruni

So you’re using (or have already used) Recap. Suggest you go back to Recap and reduce that density because a billion+ points in AutoCad is ridiculous.

Reduce to 1 point per square meter. You can always go back and increase the density later. As it is right now you need to resolve the lag issue, maybe even a crashing issue.

I’m guessing your point density right now is something like one point per 0.18 sq meter so reducing density down to one point per 1 sq meter is huge. Your 1.8 billion total points is overkill.

Your post belongs in Recap or the Civil3D or the Map3D forum, not vanilla Cad.

Thanks for the suggestion, I'll give that a try. I'm new to this point cloud stuff. I did create a new drawing and inserted the point cloud into that and so far it seems to be working ok. I think I might have done something work in the first drawing but all I did was add a few lines and a couple UCS. The strange thing is the old drawing was about 1,600KB and the new one is about 400KB but they both have about the same amount of info in them.

At this point I guess I'm gonna have to chalk it up as operator error.
