Sounds like an out of memory error. Does it happen on all files? If you make a ridiculously simple file, like just a rectangle, and export it, does it still happen? Try it on a blank file, not a template.
Maybe I'm completely wrong, but I'm looking for a way to create something like "saved views for sheetlayer viewports" :
In general, my sheet layers are for example top view sheet, front view sheet, side view sheet, one or two isometric sheets plus some detail sheets. Let's call these "sheetlayer types". Now the different crew on the building site needs different layers and classes in these sheets, for example the light crew needs fixture and truss layer, the scaffolding crew needs the steelwork layer, the rigging crew needs the truss layer and the layer of the venue roof, the stage crew needs the layaer with soft goods, and so on. So the problem is that for example a number of 5 "sheetlayer types" and 8 construction crews will lead to 40 sheet layers, all of the same shape only "filled" with different layer and class settings. So, maybe I simply can't find it, but is there a way to store only the 5 "sheetlayer types" plus 8 "views" and combine them as needed for printing ? Can a script do that ?
Whats more, any idea how to update the titleblock accordingly ?
It actually reduces a lot of the training too. Just about everybody knows how to use a web browser. And nobody needs know how to configure/trouble-shoot firewalls, VPNs etc.
I've long been in the native-is-best camp, particularly with regard to Mac desktop. But seeing Onshape in action has completely changed my mind on that front.
