I'm not familar with the "single point" error you are describing as a cause for the inability to delete pages, though I've seen a couple of cases of a single point object causing odd behaviors during export. I don't know what sort of scripts or cod you've got, but I managed to get rid of these stray objects by doing a Select All on each page and looking very carefully for single point objects (I was never able to select one of them using the mouse, even when drawing a marquee around them).
By shift-clicking on all the objects you want to keep you can remove them from the selection, then delete the offender.
It keeps saying 'requested operation would cause one or more objects to be too small. please check whether the stroke weight is too large.' I've tried doing what you said, but I can't find a single point. perhaps this isn't my issue. Any ideas of what else it could be?
You get an object too small error while trying to delete pages? I've never heard of that. I've seen it while trying to scale groups, though, and often dragging slower cures it. Of copuirse it's also possible that you are trying to reduce the size of something so that it really is too small.
What's the history of this file? Did you start from scratch in CC?
Have you tried an export to .idml?
Started from scratch in CC. It contains many pshop and Illustrator drawings. I have a few groups. Shall I go around ungrouping.. would that work?
I don't think that has anything to do with it. You're trying to delete pages, right? All of the things you are descrbing should have nothig to do with whether you can add or remove pages.
Again, have you tried .idml? see Remove minor corruption by exporting
Yes i'm trying to delete pages, it doesn't matter whether there is content in the pages or not, it just crashes everytime. That's why I was suggesting other things in the document. I think when you delete a page, it automatically reshuffles the order, thus moving this 'error' around and causing the crash. I just can't work out what the error is. I'm going to try an IDML export and re-import. I'll report back.
Saving as IDML and saving as a new file seems to have sorted it. I hope there aren't any side effects of doing this that I am yet to find out. What a weird problem. I'll try not to use the pen in ID in future!
Thanks for your help.
