Drawings Destroyed After Component Addition/Change

grenier4 — Fri, 15 Aug 2025 15:46:44 GMT

Here is an example hierarchy to explain what has occurred:

Design A
- Design B
  - Design C
    - Component C.1
    - Component C.2
    - Component C.3
  - Design D
    - Component D.1
    - Component D.2

I am creating drawings from Design A. I create sheets for individual components and I create individual drawing views for C.1, C.2, C.3, D.1, D.2, etc by selecting them in the model tree and creating views from the selections. I also create sheets each with a drawing view for B and all its sub-components, C and all its sub-components, D and all its sub-components, etc. I have almost two dozen drawing sheets from Design A (in one drawing file).

Here is what happened:

During detailing, I noticed Design C was missing a component, so I opened Design C and dragged in the missing component (added a C.4). I also noticed C.2 was missing a hole. No problem... I opened Design C, rolled back the history to where C.2 was being worked on, created a sketch, cut the hole, rolled the history forward, and saved it. I used Get Latest to update everything. When I did this, the drawing view for C.2 suddenly had C.1, C.3, and C.4 enabled. The drawing view for C.1 suddenly had C.2, C.3, and C.4 enabled. Fusion suddenly assumed that I wanted every sibling component enabled in those views even though they weren't enabled before and no changes were made to C.1 or C.3. Additionally, in the drawing view for D.1, all parent designs/components and their children became enabled; B, C, C.1, C.2, C.3, C.4, D.2... all became enabled. NO CHANGES were made to component D.1 or its parent Design D... yet these drawing views changed.

The result is that a drawing that is supposed to look like this (components D.1, D.2, etc in the example):

Now looks like this:

In my opinion, this is catastrophic. To fix this, I have to manually disable what is not supposed to be shown in each of the views. This is extremely time consuming because it's very difficult to tell what drawing views are supposed to be what components. The only slight saving grace is that when you get the right components enabled, the annotations do seem to restore without losing their associativity (a small consolation given the severity of the problem).

I truly cannot make sense of this problem. This is so severe it could drive me to stop using Fusion entirely. Is there something I am fundamentally misunderstanding or misusing? I don't see any consistency in the behavior, of which drawing views might be destroyed by which changes. I understand it is difficult to decide what to do with a new or changed component in existing drawing views... for some users/situations it may be more desirable to have a sibling default to enabled vs suppressed, but the behavior I'm experiencing is extraordinarily unacceptable. In my opinion, Fusion should understand that a drawing view was created by a specific selection of a component, and not introduce new parents or siblings into that view unless explicitly done so by the user. I understand new child components being automatically added... but siblings and parents? Why would anyone want those to be added to a view of a specifically selected sub-component?

I am truly beside myself. This could destroy an entire project in the blink of an eye. Please, someone help me.

Note: The true hierarchy of my project is obviously more complicated than the example above. There are more nested designs and components, Derived is used at times, etc. Perhaps there is something about my hierarchy and feature use that is breaking some functionality of drawing updates?

Note: Months ago I added onto a thread in the Design, Validate & Document Forum about the same sort of issue. There were never any responses or resolutions there.

Here is another similar example using Arrange and individual drawing views of the individual Envelopes. A new Envelope6 was added (sibling to the existing Envelopes 1-5), and Fusion decided this new sibling should be enabled in the views of the other singular siblings. This is extremely unhelpful behavior. Each drawing view is a selection of one sibling... no new sibling or parent level components should be introduced into these views without intentional confirmation by the user.

Sorry for the late response. Thanks for sharing the issue.

Now the new component of the top level is invisible, but for the new component of sub assembly, it does not works as expected. It is the right requirment to hide the new component of all levels. I have tracked as new ticket and sent it to Dev team for further investigation. DID is FUS-215208.

Thank you for the reply. Be advised, the issue I've had also seems to occur as a result of changes to existing components... it doesn't seem to be strictly due to the addition of a totally new component. The behavior doesn't seem entirely consistent. Any idea how long it might be before this is addressed? Is there a way to track the progress on tickets?

I have reminded dev team of the user feedback, and ask to plan this issue as high priority.

Thanks for the patience and understanding.

Hello @grenier4

This issue has been resolved and the fix will be available in the November release.

When a sub-assembly > child component drawing is created using the Select Component method, subsequent changes made at the sub-assembly or top assembly level will no longer affect the child component drawing sheet.

Please refer to the attached AVI for more details.

@anirudha_kulkarniHVD7C I am reporting that this problem is still occurring. I created a new Design, dragged in an external component, and produced a drawing of a sub-component of that component (by right-clicking on the sub-component and choosing Create Drawing). I later added a secondary external component by dragging into the same Design (becoming a sibling of the previously added component). This new component automatically became visible in all previously made drawing views of the preexisting component's sub-component. This is not desirable behavior. The added component should not damage drawing views of siblings found in the same design, or drawing views of sub-components of siblings found in the same design. This problem does not appear to be fully solved.

I have found another situation in which this problem is still occurring. I had a Component (A) consisting of some Bodies and two sub-components (A.1) and (A.2). I created a drawing with multiple views of the sub-component (A.1). I then later converted one of the Bodies in (A) into a new sub-component (A.3) using the "Create Components from Bodies" command. This new (A.3) sub-component automatically turned on in all the drawing views previously created of (A.1). This doesn't make any sense as they are siblings to one another. I can understand (A.3) defaulting to visible if it were a child of (A.1), but it was not. This is again requiring me to go to every preexisting drawing view and turn off that sibling component that I don't want seen.

Thanks for sharing the details.

Testing these cases in latest build, they are still reproducible. I have reopened the internal ticket for further fixing.

Hello @grenier4 Due to the above fix, a major regression was introduced. As a result, we reverted these changes in the November release. We are reworking this issue and plan to fix it as soon as possible.

Re: Drawings Destroyed After Component Addition/Change

grenier4 — Mon, 12 Jan 2026 16:31:14 GMT

Thank you for the update. I have projects with a lot of drawings that are likely to be affected by this issue, which will cause me to lose a lot of time fixing drawing views after components are added or modified. Please fix this as soon as possible.

Re: Drawings Destroyed After Component Addition/Change

grenier4 — Tue, 31 Mar 2026 03:32:16 GMT

Are there any updates on the fix to this problem?

Re: Drawings Destroyed After Component Addition/Change

anirudha_kulkarniHVD7C — Tue, 07 Apr 2026 04:42:58 GMT

Hello @grenier4 We are planned this ticket and working on this issue. I will update ASAP on this.
