MASSIVE Lag when selecting objects and genearal working in environment when structure browser is ope

tslewis71

Running 20.0.1.07

I basically have started to give up on this until i made sure the structure browser was not open. Taking 60 s to select and edit an object in a small model 16 GB ram, NVIDIA 2070 super. Ridiculous.

If i make sure structure browser is not open when selecting and editing objects its a x100 times faster. Anyone else experiencing this?

Michael Mayer

Yes.
With complex files it is not very snappy.

But the problem is, I can't work without having the Structure Browser.
It is even a bit worse on macOS, where there can be additional Selection
and UI issues inside Structure Browser

THIS IS ACTUALLY UNUSABLE, I CANNOT DO ANYTHING WITH THIS LAG,

Had an email from support today that said new releases addresses structure browser performance. VERY impressed so far with bricsys support and updates.

Michael Mayer

Yes, I already found the Windows V20.2.05 and installed.
Structure Panel works great and snappy.
(For me it it always mostly did under Windows ?)

Now I am waiting for the Mac and Linux updates.
Where, especially on Mac, the Structure Panel in general
is a totally different experience.

based on testing of my prior problem model looks to be much better performance

Great, it performed pretty terrible for me before this update.....Almost unusable

May need to test it on Windows with my problem Model too.

Hmmh,
Selecting (right Clicking) on a Group of about 13.000 building elements
(from about 30,000 in total)
in Structure Browser for isolating and refreshing the single! View Window*
still takes minutes for me ....
(And somehow isolating/refreshing View does not succeed ?)

And just clicking on the "+" to extend in Structure Browser will Select
everything below unwanted nevertheless ?

Hmmh,
beside that, like graphically selecting in View, it feels quite snappy somehow ....

Ryzen 3950X, 64 GB RAM and also RTX 2070 here on Windows ....

Michael Mayer

Well,
and Autosaving such a 210 MB Files can also hold you from work
for maaaaaany seconds.
Screen Refresh Rate looks like about 2 FPS for View dragging and
rotation.

Maybe related to my crappy geometry, once RVT imported by Vectorworks,
still containing lots of useless Block single-Instances, containing crappy
loose 3D Faces or Surfaces.

Maybe it would be better with proper Solids from Bricscad only.

I think my problem here is more about the File Size and number of Entities
itself. It is laggy but somehow manageable and does not crash.

So if Structure Tree got faster now
(the tree itself feels snappy - Thank you!)
maybe there are ways to improve object handling, file saving and view
regeneration too.

I am very confident with Bricscad for my typical Project Sizes and when
created from scratch in Bricscad.
But I fear that I will get more and more of those crappy and complex
RVT-only exchange files in the future.

did you see the BIM tips blog here, pretty useful....

Try the multi thread options..

What are your system specs? CPU and GFX card.

I always have all MTFlags on.
Similar machine to yours.
Ryzen 3950X, 64 GB RAM and also RTX 2070 (without super)
here on Windows 10 ....

When I select a few thousand objects graphically in view window,
and assign/change building spatial location in properties palette,
Structure tree will blink and shake in about a GHz frequency.
That looks and feels very fast

I think the most problematic thing are these useless Block
single-Instances, containing crappy loose 3D Faces or Surfaces.

I am not so sure what options I could have to clean up such projects.
I can't edit and clean up thousands of Blocks.
If I explode these Blocks and get dumb Faces,
that would prevent from all BIM Automation goodies like Bimify.
And not sure if separating Buildings into extra Files and Referencing
is always a good idea.

Will have to play with it a bit more.

i find using audit and then DMSIMPLIFY is often needed before bimifying. Will blockify help with blocks? XREF? Im still learning how best to use this software. I am using a macbook pro 2017 with i7, 16 gb and an egpu - nvidia 2070 super

Michael Mayer

Yes, I simplify(all) everthing every now and then.
I am a bit more carful with audit.
As it often simply just deletes some of my crappy imported geometry

I am still not familiar with (unnecessary) complexity of ACAD Blocks
and their best workflows in Bricscad.
Similar with XREFs. Seems ok when only drawing in Bricscad only
but not sure when you split existing Files from imports.
Like I think it gets complex to organize when they should share the
same resources or if I may need to access and edit all at a time or not
and such things.

For now I am not sure if and where Structure Browser got faster now.
If it is still faster to work when I close it or not.
Tree itself fells snappy overall, not sure what really causes the lags,
the calculation of property or command changes, the auto backup saving
that always kicks in after I edited a Block and go out or just the refresh of
the view window.
At least it is not very real time for me here.

also wondering if simplyfing the tree would help in a user defined configuration

Michael Mayer

I have build some Structure configurations.
Like sorted by Layers
or
by BIM TAGS and composition and object size but no Spatial locations
or
by geometry Type and ...

Mainly for managing, sorting and cleaning of my Geometry.

But it may be worth to filter out lots of unnecessary object types
to speed up the Structure Browser - if that really is the culprit.
