after long time, based on a discussion with another user, I tried to use point clouds in MicroStation CE Update 16.1. And it is disaster, especially in a context that one from "the release theme" is performance optimization.
When even simple POD file with just a few millions of points is attached, MicroStation response randomly (especially when element selection is used or a view should be rotated) drops down, for a few seconds MicroStation does nothing, GUI is redrawn and blinking. So, U16.1 is not usable for any project, where point clouds are used.
I have no original Update 16 installed, but when I tried Update 14 on my notebook (which is 10x slower, because only old mobile Nvidia card is used), it's not perfect, but acceptable, and without halted MicroStation moments.
I tried to search for similar issue, and I found only this discussion, and I also received information that (probably) bug #672552 is logged for this issue.
Can somebody from Bentley confirms it is known problem and for what release the fix is scheduled? It's important to warn users, using point clouds, to do not update from U14 or U15.
Well, I have an idea:

I guess there is no reason for new idea (which should be "how to add something new" section), when it is confirmed issue with bug number assigned.

it's interesting and I am curious why you do not experience any issue.
I tried similar amount of data (about 11 mil. points), using both wireframe and illustration display style, I tried to model simple geometry that fits the cloud. Nothing complicated, just basic 3D solids, and using basic tools like snap, element selection, move/copy elements. Nearly immediately MicroStation stops to respond in some operations, especially when a view is zoomed to a detail, where the cloud is larger than a view and 3D elements are displayed in a view together view the cloud (in general position, above, in and bellow the cloud).
Rod Wing said:I would also expect this problem to show up in ORD 2021 R1 since that uses the same platform as MicroStation U16.
Initially I tried it with MicroStation CE U16.1, because one from my users told me about this issue he reported for U16 and he realized it is not fixed in U16.1. Based on you comment I tried the same file in ORD CE 2021 Release 1 and the problem is there also (personally I think a bit worse).
For illustration, simple point cloud with "just some 3D elements". When I tried to use Element Selection and click on a solid in View 1 (Iso) ... dynamic snap stop to work in this case ... both MStn and ORD hangs for long time. To draw anything in View 1 using snap is impossible, to move or copy too.

Everyone says that their bug is more important to be fixed, wait in a line, if it is issue in 16.1 then in U18 it could be fixed.
