Sketchup 2017
When I create a model then close it I can only open it as read only!
So I have to open as read only then save it as another model, but then the same happens with the new model when it’s then closed and tried to re open ??
A warning appears ? Any ideas how to fix it ?
Where are you keeping the SKP file? Typically when a file opens as Read Only it’s because it is being opened from a location that SketchUp can’t auto-save to.
Hi Dave,
Google drive !
I did wonder! It’s only started as the model has grow larger.
Would you suggest C drive only.
I have only just started using sketchup along side Trimbles Tekla structures
The general wisdom is to save to a local drive and sync to your Google drive or other cloud-based storage.
Very likely in your example, it’s the access time that would be a problem.
Dave,
You are a star… works a treat.
What a wonderful program.
Hopefully I will be able to help someone some day 
Ok that worked wonders.
But I have been using layout for about 3 weeks on 1 month trial, all working great.
Paid for full license today. Just opened it and now it keeps crashing.
the tray is stuck up the top left corner!
If I try to do anything it just crashes.
Make sure you send in every BugSplat report. (“The squeaky wheel gets the grease.”)
Sorry to resurrect an old thread, but I’m also having this error appear sporadically in SketchUp Make 2017. I’m saving to my Dropbox and it works correctly 90% of the time, but occasionally when I make a new version of a file via “Save as…” the old version gets stuck in “Read only” mode and I can’t open it for editing. I don’t know how to force it out of this mode. If anyone has a good workaround, I’d love to know.
Don’t save to Dropbox, in fact don’t even save to a folder that syncs to drop box. Work your files locally then copy to dropbox whenever is appropriate.
Saving to any network location can cause issues. Many people go their whole lives without a problem, others end up with corrupted files. The risk is that dropbox syncs at the same time as a save and causes a problem, this may well be what is causing your issue, a dropout in the connection or it may be unrelated.
Save to a local folder on your computer and copy over to Dropbox when finished. Saving directly to the cloud can lead to data loss.
