ShowOsnap is switching to Off by itself

ShowOsnap is always off when starting rhino, even though I always keep it on.


Yep, known bug, don’t know if it’s going to get fixed for the first release version either…

Hi Bogdan - does this happen every time you start or only after an update?


In my case, every time the Beta/RC is started. --Mitch

Even I find the same problem.
First access to Rhino: Onsnap does not appear automatically.

You have to click on “Onsnap” to bring up the bar

Hi pascal,
It happens every time.

Same for me.

Hi all - just as a test, can someone please try setting

Options > Advanced page >
Rhino.Options.Advanvced.ShowObjectSnapDialog to True

and then close Options and then close and reopen Rhino. Shot in the dark, and not a real overall solution, but I am curious to know if that setting sticks if you set it explicitly in Options.



I can not find Rhino.Options.Advanvced.ShowObjectSnapDialog in Options > Advanced
Perhaps I’m overlooking it. Where should it be in the list?
(6.0.18012.13241, 1/12/2018)

It is Rhino.Options.Appearance.ShowObjectSnapDialog

Set it to True, closed Rhino, opened Rhino and the OSnap bar was visible.

Here it is …

Hello - so, is yours set to True and OSnaps still do not show when you close and re-open Rhino, or? What is the behavior of the OSnap toolbar if this is set to True?


Hi David - thanks - I think that supports the idea that it’s a flaw in how Settings is being handled. Looks like a 6.1 item for now. Hopefully the Options setting is an OK workaround for users who encounter this in 6.0.


Pascal - The OSnaps bar now is showing when I open Rhino, even when I opened a file saved last night which has Rhino.Options.Appearance.ShowObjectSnapDialog as False in Options > Direct.

Hi David - that should not depend on the file opened- it is a application level setting - so, if I am thinking about this right, you should be all set… but we shall see, it may be that the opposite problem will occur - it won’t stay closed - if we’re not writing that settings file correctly.


I was just able to reproduce this problem. See my comment in RH-43515 and let me know if this is consistent with what you’re seeing.

Yep, that sequence shows the problem here.


this worked for me, thanks.

In my case the Rhino.Options.Advanvced.ShowObjectSnapDialog resets itself to False every time I open Rhino V6 (not just after an update).


Same in my case. It resets to false, plus shifts location as I’ve mentioned in other posts.
