[MStn CE U16.1] Performance drop when point cloud is attached

Hi,

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.

With regards,

  • Hi Jan,

    As you already  know, we  have filed Bug 672552-> Handling of Point Clouds in Update 16 slow performances, unresponsive. 

    When wanting to rotate a view, it takes up to 2 minutes of processing to be able to use the function,  MicroStation becomes unresponsive for a while. This also applies to all View related functions besides zoom when working with Point Clouds.

    This  Bug is not fixed yet and in theory it has been scheduled  for  MicroStation Update 2023. MicroStation Update 2023 will not be released in 2023 but in 2022. 

    Bug 672552 is scheduled to be resolved in Q2 2022

    Issue is not reproducible in MicroStation CONNECT Update 15 or SS10.

    Regards

    Maria



  • Hi Marcia,

    As you already  know, we  have filed Bug 672552

    Thanks for the confirmation, because I did not find the bug mentioned in a discussion, so I was not sure.

    is  this  what you are referring to?

    Yes and no. I experienced the same problem with view rotation, but there is also problem with element selection, e.g. when there is a simple element (like slab or sphere) in the same view as view, to select element (A) does not work at all or (B) MicroStation hands for seconds or even minutes. And it is not problem with Element selection tool only, but with any selection like Copy element or Move element ... so in reality, nearly no tool can be used when working in a view where point clouds are displayed.

    This  Bug is not fixed yet and in theory it has been scheduled  for update 2023.

    Ok, the message for users is: Prefer Autodesk. I cannot imagine the users will wait more than a year to be able to use point clouds in MicroStation. It's about to pay SELECT fee for this period and not be able to use the product for any serious work?

    And I guess it's not only about MicroStation, but the same problem exists in ORD (ok, let's move to Civil3D) and OBD (final push to migrate to Revit).

    Issue is not reproducible in MicroStation CONNECT Update 15 or SS10.

    Yes, that's probably correct (I have no U15 installed, but U14 is fine).

    Regards,

    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.
