Update All Viewports?

[EAlexander]

So... does Update All Viewports update ALL viewports, or only viewports that need updating throughout the document?

[Pat Stanford]

I believe it Updates ALL viewports.

[EAlexander]

Yeah - that's what it looks like. Bummer.  Thanks Pat!

[Pat Stanford]

I THINK this script will do what you want and only update out of date viewports. Test carefully. I only used it in a file with 6 objects and 2 viewports.

 

And to prove out assumption, time how long it takes an Update All Viewports to run versus the script.  If it it much longer than we are right. If it is shorter or about the same them only the out of date viewports are being updated.

	End;

	ForEachObject(Execute, ((T=VIEWPORT)));
End;

Run(UpdateOutOfDateVPs);

Oh wow!  Thanks Pat - I'll do some testing on a duplicate file and report back!

I wrote a script a while back that will launch a dialog box showing all viewports in the drawing, with out of date viewports shown in red.  There's also a button that lets you select all out of date viewports.

Be sure to actually check to see if it did update all the viewports.  I find sections to be sneaky little buggers, sometimes they just don't update.

Per Grant's warning, I think the script will update all Sheetlayer Viewports, but Section VPs do have a separate sub-object type and may need to be handled separately in the script.  Let me know if you find this to be the case.

 

Or just run Jesse's script instead. I trust he has all the edge cases worked out. 😉

@trashcan mentioned a bug in VW2022 where the Update All Viewports command doesn't seem to work with any viewport with a BG Render set to Hidden Line.  He confirmed that my script does not have this limitation.

[trashcan]

@Jesse Cogswellis correct. There is a bug, I think from VWX2021, actually, that is solved by your script! Which I use all the time. 

 

(thanks again)
