Drawings - Suppressed components become unsuppressed

[gvisca44]

Hi there, 

I seem to be battling an issue with drawings that is driving me a little crazy.

I have a master assembly (a complete product) that consists of several linked sub-assemblies, each with their own differing layers of sub-assemblies and components.  It is primarily sheet metal (100 or so individual sheet metal components), with other bits and pieces included.

My drawing file is created off the master assembly, so I get a single file of all desired components running into multiple (100+) pages.

The workflow with most of our sheet metal fab suppliers is they get DXF files of each part for cutting (or a nest ... but thats a side topic), and drawings that describe the folds.

So - the drawing sheet of a component consists of:

1: The sheet metal flat pattern with folding table and, 

2: The 2D folded view of that same part and, 

3: An Isometric folded view in the top right corner for reference.

The way I have been doing this is to :

1: Create a base reference to the sheet metal flat pattern.

2: Create a 2nd base reference to the component front view - and then take off projected views as required including the ISO view.

So - use of the "SUPPRESS ALL EXCEPT SELECTED" is used a lot!

However (as happens), as small modifications are made to the various sub-assemblies, when I go back into the drawing file and perform an update - all the previously SUPPRESSED items are now strangely unsuppressed ... and any new components that may have been added are also now UNSUPPRESSED.

Any ideas ?

Hello @gvisca44 

Can you please post a screencast video of the issue you are facing? We tried to reproduce but couldn't reproduce it. Maybe we are missing out on something or some key step.

Also, if it is an issue you are facing with a particular assembly would you be able to share the assembly as well? If you don't wish to attach the assembly here you can share it with my work email id rohit.bapat@autodesk.com

Thank you,

Best Regards

Ho Rohit, 

I am yet to put my finger on the exact circumstances when this occurs ... but I will try to make it repeatable and send something through.

While exploring the drawing workspace I have been trying to use the same operation. It does seem to behave a little flakey. And I was only working on a single assembly with a handful of linked components. I'll be watching this to see what you find out.

Hi Rohit,

Hi @stevesneadH8U9D 

yes - there are a few things I have seen ... but thus far I have been unable to make the problem occur repeatedly.

e.g. 

* sheet metal flat patterns "selectively" visible from the drawings workspace.

* unable to reassociate unassociated dimensions or fold call outs.

* an inordinate amount of processing time if a model file changes (however ... this may be my aged PC ...)

Any resolution on this issue?

Hi,

i have the same issue. After I save my model the drawing updates with previously in suppressed components. Very frustrating and time consuming.

I am also having the same problem and it seems like my file is set up similarly to OP. I have a master assembly that contains multiple smaller assemblies, but only so that I can keep all their drawings consolidated in one file. I'm doing this because Fusion doesn't seem to have any centralized drawing management (akin to the Sheet Set Manager in AutoCAD), so I'm trying to reduce the number of separate locations my drawings are stored. (If there is a drawing manager please let me know). Here is a drawing in my file, you can see lots of suppressed components in the tree in order to create detail views of various sub-assemblies and parts...

Before Component modification

I made a small change to one of the suppressed components (the addition of two hex nuts within that design). This change had nothing to do with what is shown on this particular drawing plate. After doing this, all the components became unsuppressed in every drawing view, giving this result...

After Component Update

Needless to say, my computer was churning on this for a while to get all of this to display. I then had to go in and use "Suppress all except selected" over and over again to restore my drawing views. This affected every plate containing that particular parent assembly, even when the changed sub-assembly was already suppressed in those drawings. It would be one thing if only the changed sub-assembly became unsuppressed, but its kicking all its siblings to be also be unsuppressed. This easily killed an hour of my time and now I'm worried about making the smallest changes to any component in this project or my drawings are going to be destroyed again.

The only help document I've found related to this is here. The "solution" described is not helpful or practical; it would take a significant amount of time for a file like this with many drawings in it. It seems like there really needs to be more sophisticated control over suppression of components in existing views whenever changes are made. Ultimately, I can't tell if this is a bug I'm dealing with or just a limitation of the drawing environment. Based on replies above I'm wondering if it is a bug that can't be tracked down?

I'm struggling to think of workarounds. One idea I had was to drop every sub-assembly and individual component I want to detail into the top level of this design. Then they would be higher up in the tree with fewer associations to one another so the damage might be more minimal or less likely to occur if components become unsuppressed. I'm honestly worried about even dropping another component into the top level of this design though... would it show up in every existing drawing view and I would have to go around and manually suppress it? I've lost confidence in predictable behavior in this regard.
