Drawing shows suppressed component

[r.moss]

I'm glad the December update fixed the issue with drawings getting corrupted as soon as the file was reopened (https://forums.autodesk.com/t5/fusion-360-design-validate/re-opening-drawing-corrupts-its-model-refe... ).   

For some reason though my drawing now shows one of the suppressed items.

The shaft in the image is from one of the "Pelton assy" components, which are both suppressed - it should not be visible.

This is on an M1 iMac.  The shaft appears whenever I add a sheet, though for some components it lies outside the bounding box and gets cropped.

Hello @r.moss 

Sorry to know that you are facing this issue. Can you please share the file with us? So that we can take a deeper look into the issue? If you don't wish to share it here you can send it to my work email rohit.bapat@autodesk.com

Hi Rohit

Here you are - see "Sheet6", also (just) visible in Sheet7

[r.moss]

Another strange thing (I've mentioned this before) - when it adds a new sheet, it adds a copy of its model reference into one of the pre-existing sheets.

So Sheet9, when it was added, had a new reference "...assembly v66.9".  If you look back to Sheet8 you will see it has its own reference v66.8 plus an unwanted copy of 66.9.   (All the other sheets had the same, it's just that I deleted the unwanted references.  They clutter up the browser - a bit tiresome). 

The sheets were added using the right-click Create Drawing menu in the parent model.

In Sheet7, try selecting one of the drawing views and dragging it slightly - you will then see the unwanted component in full i.e. uncropped.

Another interesting thing: one of the sheets will only show as a line drawing.  If I try to shade it nothing happens - see screencast

Hello @r.moss 

Thank you for the details and the dataset. I was able to open the assembly but I did not see any drawing file in it. Can you please share the drawing file so that I can follow the issues you mentioned and investigate a bit more?

Hi Rohit

I have attached the model's .f3z file below (27 Mb).  When I exported the drawing it came to 108 Mb which is too large to attach.    I'm not sure why it is so large - I had imagined the model references were just links rather than multiple copies of the original model.  Maybe the shaded views are high resolution bitmaps?  Curious.

How can I send you the drawing file?

Hello @r.moss 

Not sure why it becomes 100+mb file? But you can share the link of the drawing file as shown in this page https://knowledge.autodesk.com/support/fusion-360/troubleshooting/caas/sfdcarticles/sfdcarticles/How... so that you don't have to attach the file here.

Please let me know if you encounter any trouble

Hello @r.moss 

Thank you for the link. I will take the files and revert you with my findings.

Hi, is there any progress on this?  I am still finding that converting a model to a drawing takes ages.

To illustrate, I will do a screencast, starting from scratch.  I have a model of my assembly.  I guess it has a few hundred components, don't know, but all I want is to make a drawing with 4 sheets, one body on each sheet, with all the other components invisible.

I could of course open each inserted component individually and make 4 separate pdf files, one for each body, but that gets messy - I just want one drawing file.

I first tried doing this on an old Dell desktop (i7-3770 3.4 GHz chipset, 16 Gb ram, SSD disk, NVidia Quadro K600 graphics card, 35 Mb/s download:8 Mb/s upload).  In theory this should be enough for F360 but it really struggled.

I then tried on a 2-year old computer, i7-9700, 64Gb ram, SSD disk, fast internet connection (320 Mb/s download, 780 Mb/s upload i.e. 10-100* faster connection than the old machine) so it really should be fast and "snappy".  In fact it takes nearly 30 seconds for a new sheet to appear and display the base projection (e.g. 6:54 to 7:21 in the screencast).  It doesn't help that it shows a phantom component: the spindle that appears in the drawing is not one of the visible components (it then disappears once the projection is completed).

At this rate it will take forever to make a sheet for each component.

If I go to "Web view" and download the .f3z files, the model and the drawing are each about 27 Mb.   I think changing the component visibility is making it refresh the whole model reference.  This shouldn't be necessary: surely it should be able to just update the list of what is/isn't visible?

The story continues!  I just changed one drawing view from edges-only to shaded and the suppressed spindle became visible.  Here's the screencast:

Hello @r.moss 

Sorry for late reply. I am able to reproduce both issues and have created a ticket for tracking the issue. I will update more once I get some insights into the problem

Thank you for your patience.

The same design also has speed problems when editing the model.  Using a fast PC (64Gb ram, 3GHz i7-9700 chipset, SSD, 800 Mb/s network connection) it has just taken me 2.5 minutes to change one of the offset values in a joint.

I've seen other posts mentioning splines and mesh surfaces which can cause slow performance.  This model has none of those - it just uses basic drawing features.  It's so frustrating!
