In the WIP 9.0.25315.12306, Exporting .Obj is blocked .
both my regular Macro and manually exporting do not work.
a very strange “you do not have permission” massage popup when manually trying to export.
Exporting is fine in R8
Hi Akash -
Is that also the case when you are exporting a simple box from a new file?
Can you post the settings that you are using when exporting?
-wim
Hi @wim
thanks.
yes it fails also with just a box in a new file.
here is the command history [ this is for my button that runs that export as a macro and works fine in R8]
Command: Box
1 closed extrusion added to selection.
Command: -Export
Command: “/Users/akashlotan/Library/CloudStorage/Dropbox/Mac (2)/Documents/ZbrushWork/From-Rhino.obj”
Failed to save as /Users/akashlotan/Library/CloudStorage/Dropbox/Mac (2)/Documents/ZbrushWork/From-Rhino.obj.
Now I tried manually to export with a different name and a different location and it worked But I didn’t change any of the export settings…. so something perhaps with the auto overwrite in the Macro is not working [just guessing ]. the Macro overwrite the file so I can quickly send to Zbrush [where I have a button with a macro to import it in one click too.
Any idea ? [I use this all the time for fast moving mesh parts between rhino and ZB so it’s really important here]
I’m trying to open this Macro to see how it is structured… but can’t seems to find how to do this in the WIP?
How about the file path. Do the parens in the folder path cause the problem?
it works fine in R8 so as far as I can tell it is something in the Wip that’s makes it fail.
I’d like to open that macro to check if it’s the same as in 8 [perhaps it got messed up when copied from R8] But I can’t [remember how to ] open it. ?
I am getting errors also. We are taking a closer look.
In my testing new Rhino WIP out on Tuesday seems to fix this. Get and update and see if it works for you also?
thanks @scottd
I just tested and it’s failing here with my export Macro. Manually it is also failing [same as before]
I’m on 9.0.25343.14056, 2025-12-09
Can we try other things:
- Can another file format be written to the same spot. Something like STL?
- Can the OBJ be written to a local file. The current folder is a Dropbox folder.
- Can Rhino write a 3DM file be written?
We need to remove the variable until it works, then add steps back to see where the problem is.
yes
it’s not a dropbox folder it’s a local folder on my computer! I never save files directly to DB. it is doing it’s sync after the files are saved locally
what you see as the strange path [perhaps it looks like this for PC users..?]. is simply the way DB is integrated within the MacOS file system.
for example a path like this
is just my local Download folder. [with a DB backup and sync in the background
Yes. It’s only failing with OBJ
And to say again. In R8 the OBJ is saving in that location without an issue with the same Macro. or manually via the Export command
I understand DB does sync. Although in some cases if we are not careful, the sync happens in the middle of the process and it confuses Rhino. For instance the OBJ might get written, but then the MTL file also needs to be written. But if DB Sync gets active in the middle of that it can get confused.
One thing OBJ does is write multiple files, I wonder if that is the problem?
The challenge here is we are not seeing the problem. Trying to change the variables on your side to determine what part of the setup you have.
Since Rhino 8 has no issue. this can’t be a DB related problem I would imagine.
But I can test this since DB in not syncing all the computer. only certain folders….
I’ll try and report back
I do not know what the differences might, be, but it does give us some clues that we can look into. Thanks for the additional testing.
Hi @Akash,
I tested with a simple file on Rhino 9 Mac WIP (Rhino 9 SR0 2025-12-10 (Rhino WIP, 9.0.25344.06306) with the latest Dropbox addon for Mac.
I have Tahoe.
The obj was written direct to the DB syncronize folder without any issue.
Can you upload or email me a file that does not work for you?
tech@mcneel.com Attn: Mary
Also please copy and paste your marco text. Thanks.
Can you successfully write the file with the Export command (not the macro)?
Sincerely,
Mary Ann Fugier
Hello @mary
thanks.
1). the file is not specific . just a box in a new file will do.
- it fails both with my macro and with the export command.
2note). I somehow couldn’t find out how to “see” the macro, I don’t remember how it was written. [kindly write steps how to open the Macro’s text in the WIP]
3]Please see, and I already wrote this many times! I’m not saving the files to a dropbox location [never had] I’m saving to a local folder. your screenshots shows saving to dropbox.
- I’m not on Tahoe yet. but on 15.7.2. [because of some important oldish intel apps that I wasn’t able to verify if they’ll run ok on MacOS26]
This issue remains that we are unable to duplicate it here.
I am saving local, but my folder is also sync’ed with Dropbox.
I do not have Somoma,
It does not. I included both for completeness.
You have to save local, and it sync with Dropbox.
I have no problem writing to a local folder or a local folder that is syns’ed with Dropbox.
Maybe other users will test this on Sonoma, but we need help duplicating the issue here on our comptuers.
Sincerely,
Mary Ann Fugier
So… I tested with a generic name to export [via manu] to my regular location [ZbrushWork] and it saved ok this time.
This is my Macro in the WIP [finally figured out how to open it]. and the thing about this Macro is that it [intentionally] overwrite the file every time it saves .
! -Export “/Users/akashlotan/Library/CloudStorage/Dropbox/Mac (2)/Documents/ZbrushWork/From-Rhino.obj”
-GeometryOnly=Yes SaveTextures=Yes SaveNotes=No
VertexWelding=Welded YUp=Yes Enter DetailedOptions AdvancedOptions
Angle=0 AspectRatio=6 Distance=0.0005 Density=1.0 Grid=0
MaxEdgeLength=0 MinEdgeLength=0.0001 EnterEnd
And the same Macro in Rhino 8
! -Export “/Users/akashlotan/Library/CloudStorage/Dropbox/Mac (2)/Documents/ZbrushWork/From-Rhino.obj”
-GeometryOnly=Yes SaveTextures=Yes SaveNotes=No
VertexWelding=Welded YUp=Yes Enter DetailedOptions AdvancedOptions
Angle=0 AspectRatio=6 Distance=0.0005 Density=1.0 Grid=0
MaxEdgeLength=0 MinEdgeLength=0.0001 EnterEnd
they appears identical to me…? and in Rhino 8 it works but fails in the WIP
Maybe there’s a better/cleaner way to write it that will work in the WIP? any idea?
Hi @akash,
I could see it on the history menu:
When I pasted your macro in Rhino 9’s Macro editor, there were carriage returns that made the commands and input out of sysc.
Since spaces are interpreted as Enter, there were extras that were affecting the Macro. So this is what I got when I removed the extra enters.
! -Export pause “/Users/mary/Library/CloudStorage/Dropbox/Water bottle/test v9.obj" -GeometryOnly=Yes SaveTextures=Yes SaveNotes=No VertexWelding=Welded YUp=Yes Enter DetailedOptions AdvancedOptions Angle=0 AspectRatio=6 Distance=0.0005 Density=1.0 Grid=0 MaxEdgeLength=0 MinEdgeLength=0.0001 EnterEnd
As you can see in the video, it works even saving to my dropbox synced location. The pause allows it to work in both preselect and post select mode.
I also put the entire macro in the alias “A”.
Use the “hamburger” menu in the lower left to review the commands that you are using and any messages that are returned.
So alias & macro editor work for me to access your macro.
My guess is that in Rhino 8 you do not have the extra enters, but when coping to & from the Mac clipboard they were introduced.
Sincerely,
Mary Ann Fugier
