Hello there!
Please can someone help me? I am using microstation V8i SELECTseries 3, I need to work with point clouds and making 3D models.
When I load point cloud to microstation with original resolution, it is so hard to work with it. I don't know if it is because low PC performance, or it is because microstation.
When I use another softwer for pointclouds on the same PC, it works with no problems, so why in microstation is problem with loading big point clouds?
When I degradate point cloud resolution in another softwer, from example from 2 000 000 000 points to 200 000 points its relative OK and I can work with it. But why I can not use full resolution in Microstation?
Is new microstation connect better in working with point clouds?
Hi gg,

What version do you use exactly? Can you provide MicroStation build number? Several SELECTseries 3 versions (original one, Update 1, Update 2...) were released and every version was optimizied a bit more.

It often makes sense to decrease point cloud resolution to be "good enough" for expected needs, but not better, and / or to split it into several files. 2 000 000 000 sounds to me like to huge data for MicroStation (as it's not "point cloud optimized" software), on the other hand my experience is that millions or tens of millions of points is fine.

You did not provide information what HW and SW configuration you use. You should be aware that many CAD softwares use OpenGL, but MicroStation use DirectX. And when graphic card optimized or configured for OpenGL and is used with MicroStation, it can provide substantially worse performance comparing to OpenGL application. I remember some NVidia cards (quite expensive ones) that work worse with MicroStation than cheap gaming cards from AMD, because NVidia optimizes everything for OpenGL and historically their DirectX support is not very good (including some software-only-emulated DirectX features).

Well ... I am not quite sure. I agree wtih Duncan that because CE is 64bit application, it's able to utilize memory better, on the other hand CE optimization and performance is still not perfect. But with graphic card supporting at least DirectX 11 natively, both V8i and CE should work fine with (at leas) millions of points.

I did say 'should' but as with all things Connect the reality does not always live up to the marketing.
thank you for your help ... additional information about HW and SW:
Microstation V8i (SELECTseries 3) version 08.11.09.459
Windows 10 Enterprise 64bit, procesor type x64
RAM: 32GB
Procesor: Intel(R) Xeon(R) CPU E5 - 1650 v4 @ 3.60GHz
Graphic card: NVIDIA Quadro P5000 16GB : Graphics APIs Shader Model 5.1, OpenGL 4.54, DirectX 12.05, Vulkan 1.04
I think this should be inaf for modeling in modern CAD softver, using point clouds with out additional degradation of resolution ... :-/

Thanks for sharing the detail. With some exagerration, V8i is able to utilize maybe 1/4 of your workstation resources ... and I'd like to have such piece of HW on my desk ;-)
Are you able to test how the latest MicroStation CE Update 10 (Update 11 should be released soon) work on your PC with the point clouds?

I guess it's enough for any "normal" engineering task (not talking about simulation of the whole Boeing model or AI learning ;-). In my opinion HW is rarely issue today, the problem is in SW optimization ... it's easier to offer new and new features and tools than to spend months and years to optimize code to maximum performance. Another problem (which is valid to MicroStation) is that single focused application will "always" behave better than universal one. As developer I can imagine that to optimize point cloud software (with zero or limited vector editing features) to super speed is far easier than to do the same in MicroStation with so many features (vectors, rasters, dynamic elements resymbolization...) and many software layers between data and display engine.
I am member of big company (volkswagen), there are some rules of administrating computers, so I can not install new softwers on my PC, anyway in close future we will use microstation CE, so may then I will know you how it goes :)
