What is this Loading Graphics for Plan View slowdown? Anybody else? 4.11

    When I load a large cad file I keep getting this. Why does it take so long? Is there a setting somewhere?

    Check Project Settings - View Settings - DIsplay and see what you Show All Lines as Solid is set to. I have had this a few times recently and if you have it set to No and you have a large CAD file with lots of dashed lines etc in it it can slow you down graphically (it is being looked at) - this came up 3x week before last and it was the answer in all 3 cases.

    Perfect! This have been an issue for us for a long time and finally we know how to work arund it, thanks!

    Alan,

     

    I'm having a similar issue and your fix did speed it up. But, I'm using custom linestyles that I created with the Line Type Editor to help me differentiate as-built underground utilities. Is there a solution that will allow me to continue viewing my line styles and still not slow everything down?

    I will find out how development are getting on with optimization work in that - while editing and getting your model as you need it use layers colors and lineweights in preference to linestyles and switch over to linestyles when ready to create outputs etc.

     

    I can look at this for you next week if you want to share your file with me so I can see what you are contending with

    We are having a similar issue in TBC Civil. We have a large roadway project with lots of utilities. Both above grade and below. Lately the refresh rate has slowed significantly. it takes up to 1 minute to refresh. Has any one else experienced something similar?

    I looked at your project and it has the same issues that we have found before - if you change the following you will find enormous change to your performance

     

    1) Go to Project Settings - View - Display Options and change the Setting called Display All Lines as Solid to Yes (it was set to No). This converts all imported CAD lines to Solid Lines from a Graphics perspective (you can revert back if you need to). Displaying complex dashed and dotted linestyles on Large CAD files is what hogs graphics memory and slows you down. We are not sure what changed on some peoples computers as all our shipping templates have it set this way, but for some reason some customers PCs have had this setting changed from the Yes to No and they have seen the "slow down" as a result.

     

    2) Your Standard Text Style is set to use Courier New Text Font. This is a True Type Font vs a stroked (vector line font) and when there is a lot of True Type TExt in a drawing that too will slow you down. I changed the Text Style for Standard to use a Stroked Font like Avongrnh which looks nice and uses the Vector Font method - this is way faster to hold in memory and regenerate than True Type Fonts.

     

    Just making these two changes made a marked difference to your project on my computer.

     

    I would recommend that you have your team download the Optimization for Speed document that I have posted on the Community - that covers many tips that you can use to make your projects faster - especially the larger projects and where you have a lot of source CAD or PDF data.

     

    Search for "Speed" on the community or use the following link to find the document

    Thanks for sharing

    Hi Alan,

    I understand that concept with the line styles and that it converts in worst case one line segment into thousands of tiny little ones. But that's more of an issue if you zoom out.

     

    But zooming out is smooth and without any delay on my machine. I have the issue with zooming in to about 30 cm and just a few lines left on the screen.

    I have enabled the show as solid and even set my lines to solid and no text visible.

     

    I've got a mid size road model with given triangles for the subgrade quantities I have to cleanup, so I'm zooming in and out and rotate a lot in 3D view. And usually with the last mouse wheel click it starts to rebuild in plan or 3D view with just a few lines left on the screen. I don't think it's line style related.

    I've got 16 GB out of 32 of RAM left, so once it has rebuilt something it could just keep it in memory all the time and not forget it within a few seconds. And looking at the Quadro graphics RAM and the main RAM, they don't seem to change  during the rebuilt. So what is it actually doing?

     

    I have the feeling it's getting worse the larger the file gets. With all the surfaces and Cut/Fill maps the file is meanwhile at 400 MB.

    Hi All,

    I found this after having the same issue almost 6 years after the beginning of this thread, and it is still happening the same way as Ronny described above.

    Any chance Trimble could fix this before a decade has passed?

    Doubt it. It's somewhat working and not completely broken. So, no reason to waste developer time and reduce shareholder return over saving us time.

    The graphics system, especially for linework, is super inefficient. It seems reasonably ok for point clouds though. I don't know what it is doing, but reloading data all the time from God knows where doesn't seem right. Memory usage seems over the top as well compared to Trueview for instance.

    With nowadays SSD transfer rates the loading of a saved project, which means memory state, should be pretty much instantaneously.

    Just a really bad example, been playing around with an OBJ file (my own macro, TBC can't read them).

    200 MB OBJ leading to 4.1 million simple 2-point start/end line segments.

    - TBC project - 224 MB - no line styles or other fancy stuff

    • loading from an open TBC instance - 3:10 min
    • loading the graphics data just for plan view - another 2:00 min
    • zooming too far in the 2:00 min rebuild starts all over again
    • enabling/disabling layer another 2:00 min coffee break, if I die from cardiac arrest, it's on Trimble
    • memory usage when empty 3087 MB
    • memory usage with file loaded 8050 MB

      - exported the lines as DWG - 228 MB

      • loading into running DWG Trueview and linework visible in 12 sec!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
      • occasionally a 1 or 2 sec delay while zooming
      • enabling/disabling layer -> linework there instantly
      • memory usage when empty 410 MB
      • memory usage with file loaded 2602 MB

      And what is even weirder, in the meanwhile I know how to add graphical overlays to the viewports via macro, i.e. to highlight a selected line.

      My slow python macro is able to "highlight" those 4.1 million lines in 30 sec.

      I'm cutting a little bit the corner since I know that the lines are straight 2-point segments and no curves involved which would require chording.

      But something for the developers to answer, why is this uncompiled python script 4 times faster than the standard high performance compiled C++ view loading???

          def drawoverlay(self):
      
              TrimbleOffice.TheOffice.MainWindow.AppViewManager.RemoveOverlayGeometry(self.ViewOverlay)
              self.overlayBag = OverlayBag(self.ViewOverlay) # create a new/empty overlaybag
      
              layerobject = self.currentProject.Concordance.Lookup(8) # as an example get layer 0 as object - doesn't even need to be visible
              
              for sn in layerobject.Members:
                  l = self.currentProject.Concordance.Lookup(sn)
                  polyseg = l.ComputePolySeg()
                  self.overlayBag.AddPolyline(polyseg.ToPoint3DArray(), Color.Green.ToArgb(), 1)
      
              # if it only needs to be visible in all Planview then remove the Hoops3DViewGUID
              array = Array[Guid]([DisplayWindow.Hoops3DViewGUID, DisplayWindow.HoopsPlanViewGUID])
              TrimbleOffice.TheOffice.MainWindow.AppViewManager.AddOverlayGeometry(array, self.overlayBag)
      
              return

      Hi Guys,  I had this exact issue as soon as I upgraded to 2024.  I had several large projects that had years worth of data, and these would take approx 10 minutes to load with the same message.

      I pushed this up to Trimble, and they suggested I delete my FXL file that was loaded.  Turns out I had an old Numeric Code FXL file.  We now converted to Alpha Codes, so it wasn't even valid anymore.

      As soon as I deleted the FXL, these old projects opened up in seconds again as before the upgrade.  Before I would wait minutes after doing a simple zoom.  I too read about attaching PDF's and all this linestyle nonsense (which I don't do).  

      Hope this might solve it for you.  I didn't re-attach my FXL as we don't draft with TBC.  Never had a problem since.
