I have the same problem,
the Objects.local file are not in the SVN server, by default these files are excluded from SVN tree if I'm not wrong maybe any expert can clarify this,
when you save the changes the SDDM try to save into the local file the change but is not in the server and then generates the error,
you can include these files into the SVN manually but then you will always have differences if the model is modified (only opening the model) by any other user,
also you need to check if you have the filter for these files enabled into the Global List Ignore files (preferences menu) and disabling the filter the SDDM will take into account these files,
you should be able to solve the problem of the error but you will have the noise extra of any change,
I hope someone from SDDM support could help us to find a solution,
Thanks in advance
svn: E155010: The node '...\rel\5AE0A03A-E9A8585E1435\DDLSelection.local' was not found.
In despite of fact, that this file is actually exists and seems to be valid:
<?xml version = '1.0' encoding = 'UTF-8'?>

That's correct. All those .local files are for local usage, Data Modeler creates/deletes them on the fly and even can work without them.
External tools also should work properly with them if you put your design into repository using Data Modeler - i.e. checkout empty directory from repository and save your design in that directory - then DM will do the job. Part of that
is putting those files into ignore list.
into the Tools/Preferences menu you have a option call Global Ignore List,
you should add "**/*.local" to the list and be sure the new option is checked,
but regarding the initial question,
how can I delete a relational model from a model if I have not this file into the SVN repository?
thanks in advance
