3D models of parts are misplaced on generated 3D PCB in Fusion 360

[krysapear]

When I'm trying to generate 3D PCB board from schematic and 2D board from within Electronic Design in Fusion 360, all the 3D models of parts are misplaced from their footprint.

When I'm generating same 3D PCB by pushing it to Fusion360 from standalone Eagle, everything is placed correctly.

Using Fusion 360 v. 2.0.7438 and Eagle 9.5.2.

Interesting. Same effect for the connectors, but my resistors from standard library do not shift.

This is  Board created from scratch with Fusion and rendered (first image, with everything misaligned), than exported and imported in Eagle where the same board was EXPORTED to Fusion as usual (second image with every component ok).

This should demostrate that the problem is NOT the library.

I also tried to create a new 3d component from fusion, but the pin mask has wrong dimensions. The distance between pins that in the Board (same Fusion and Eagle) is 2,54mm (100mil) when exported for creating the component became 2mm.

Hope this can help to find the problem...

Thanks for your email.  Can you export the 3D model and the lbr file you are using and send them to me directly?  You can reach me at matt.berggren@autodesk.com ...I am super keen to find and fix this if this is with the translation step. 

Also curious, can you open the Fusion preferences located under your username in the upper right and screenshot the  Preference settings / Grid settings below (I dont have a theory yet, but I want to have this in my hands in case I need it).  Thank you!  We will get to the bottom of it!

Best regards

same issue here, manually created library, perfect alignment and scaling in packages editor, then everything goes mad in 3d pcb viewer

Hi @krysapear et al.,

Sorry to hear that you're having trouble.

Before this issue is addressed, could you please try below workaround to remove the cached files (.f3d and .txt) from the circuitslib folder and try again?

I posted the workaround in another thread too: https://forums.autodesk.com/t5/fusion-360-electronics/wrong-designation-in-3d/m-p/9378785/highlight/...

You could find the circuitslib folder from below path on your Windows OS:

C:\Users\#### YourOSAccount ####\AppData\Roaming\Autodesk\Autodesk Fusion 360\### YourAccount###\circuitslib

By the way, if your OS is Mac, you could find the circuitslib folder from:

Users/###UserName###/Library/Application Support/Autodesk/Autodesk Fusion 360/###YourAccount###/Circuitslib

Hope it helps.

Thanks,

Helen

Hi @HelenChen-ElectronicsQA ,

unfortunately it does not work for me...  I even deleted everything in AppData related to Autodesk, reinstalled newest version of Fusion from scratch...
But when I want to create 3D board from even a few random parts added (from included Fusion 360 libraries), I still get 3D models displaced:

Hello @krysapear ,

Much appreciated for your fast feedback.

Could you please share the screenshot of your circuitslib folder? 

Also do you mind save the Electronics Designs and export them into f3z file and send to me? I will private message you my email address. Thank you!

Regards,

Helen

Hi @HelenChen-ElectronicsQA ,

my circuitslib folder is empty. It was not when I was using older version, but I deleted whole Autodesk folder and installed new version of Fusion after...No new files in this folder since then...

[krysapear]

Hi @HelenChen-ElectronicsQA ,

Attached you can find my very simple test design:

new Electronics Design -> new Schematic ->  only a few random parts added to schematic -> Save Schematic -> switch to PCB -> move the parts to board area -> Save PCB ->  generate 3D PCB -> Save 3D PCB -> Save Electronic Design

But still I get 3d models misaligned

Hope it helps

[HelenChen-ElectronicsQA]

Much appreciated @krysapear ,

Unfortunately we are still not able to reproduce the issue if move any part in your 2D PCB and view to 3D PCB, I have replied your email with some follow up questions.

Please have a check, thank you so much for helping us narrow down the issue.

Regards,

Helen

This is still very much a problem, and one of the biggest imo! I have a pretty decent project in size and had problem with misaligned and misplaced components as the pictures in this thread (all components 3mm ish wrong in X and Y), and the problem actually disappeared when updating fusion a week ago, until now when updating to the latest release as it occurred again. 

I don't know if there's an "unintended fix" in the previous release or if it was a deleted cache or something when updating that made it work for a while. 

But still, this can't be that problematic to reproduce. Can I send you some files or something to help out now when mine are broken again?

It seem like there's an "origin problem" between the different sheets and component libraries that collide.

Hello @Sebastian_Galo ,

Much appreciated for your feedback.

It's really very strange that we got few problematic designs from other users, but if we move the part in 2D PCB and then view 3D PCB, all the parts positions works well for us...

If you reset the preferences settings to default and try again, are you still able to reproduce the same issue?

We really eager to find the reproducible steps from scratch, then our development team could debug it locally. So could you please help to answer below questions and let's see whether any pattern might be found from other users who have the same issue?

• What’s your OS type and what’s the version?
• What’s your OS language?
• What’s your Fusion language?

Thanks a lot.

Regards,

Helen

Hello all,

I tried one more thing... I put preferences to default settings, cleared the cache from Support and Diagnostic menu in Help and restarted the Fusion.

In my project with nearly all models misaligned, I selected everything on 2D PCB (with Ctrl-A) and moved the whole board a little, so the bottom left corner of the board is not on origin 0,0 mil, but e.g. on 100,100mil coordinates - and then switched to 3D PCB and every model was in the correct place...

I tried it in other projects (I had misplaced 3D models everywhere) and it worked there too... 

Not sure for how long it will stay like this, but so far it's the best workaround for me...

Hope this can help you find solution 😄

Hi Krzysztof,

Thank you for taking the time and update this post. I will let the developers know about this.

Best Regards,

• What’s your OS type and what’s the version?
  • OSX Mojave and Windows 10. Going between two computers. No difference, problem still occur. Both updated to latest Fusion version.
• What’s your OS language?
  • Mojave in English, and Windows 10 in Swedish.
• What’s your Fusion language?
  • English.

I will try to reset preferences and also move my design in X and Y to see if it works for me as well.

Mine looks like this now. Had problems with components flipped 90 degrees and misplaced in Z coordinate as well earlier, but updated some of them and it looks more "equally wrong" now (even though everything actually are misplaced in different ways as you see, which is very weird since they share footprint design!).

Hello HelenChen,

I had the same problem, I created a new electronic design only with few components (resistors and capacitors) from the Fusion library and the 3D PCB was also misaligned. Then I changed the 2D PCB grid to 10 mils and move all the components on the board, afer that the 3D PCB was aligned, I changed back the grid to 50 mils and it stays aligned.

Maybe this would help to find the problem 🙂

Thanks

Hi @Anonymous ,

Thank you very much for your feedback.

It's so glad to hear that you workaround it by changing the grid unit size. 

So your default grid unit size is 50 mils, right?

Regards,

Helen

[HelenChen-ElectronicsQA]

Hi @Sebastian_Galo ,

Thank you very much for your feedback.

Could you please try to change the grid unit size as @Anonymous just mentioned above and try again?

Or how about the workaround shared by @krysapear  mentioned above too?

In my project with nearly all models misaligned, I selected everything on 2D PCB (with Ctrl-A) and moved the whole board a little, so the bottom left corner of the board is not on origin 0,0 mil, but e.g. on 100,100mil coordinates - and then switched to 3D PCB and every model was in the correct place...

Thanks a lot.

Sorry to say, no difference when changing grid size or moving the PCB from origin and back. I was looking though a tutorial at the release of electronics for fusion and they said very clear that one should not change the grid size. Don't know why, but it doesn't seem to make any difference anyhow.

In my case there's also something problematic with the sketch from PCB 2D to 3D. When I change PCB size and component placement the cutout sketch doesn't update placement. Now the card went from green to brown as well...

I do got some "broken links" between schematic and PCB 2D, it says it's not consistent. Think it's something with the versions. But this shouldn't affect the 2D and 3D models anyway. Just want to inform you about my specific project in case it actually matters. Will try to solve this and see if it makes any difference.

Hello HelenChen,

Yes, my default grid was 50 mils. Unfortunately when I added a new component on the schematic and the PCB was on 50 mils grid, everything was disaligned again and even the solder layer disapears from the 3D PCB and it turned brown.
