Viewport expands with scale change

[AllenJessup]

I've had this happen a few times. I change the scale on a viewport and instead of the view inside the viewport changing. The viewport expands (Scales up) to hold the extents. The viewport is not locked and USCFollow is 0.

Edit. I tested it and found that starting at an 80 scale I can reduce to a 70 or 60 scale. Once I go below a 60 scale. That's when the size of the viewport changes. Also this only happens using the viewport grip. If I use the Properties Pallet the viewport doesn't expand.

I have this consistently happend, if I scale to 1" = 40 the view with expand in size to retain the view area. If I scale to 1" = 250 it will get smaller , yet still retain the view area. I actually stopped using the arrow for the drop down scale list  because of that.

Pretty much the decision I've reached.

@BlackBox_ has a tool on the Apps Exchange that I've been using to fix this and works great.

Hi @AllenJessup 

I always thought that was the normal behavior for the center scale grip (granted I also don’t like it personally!). I typically change the scale from the status bar to scale the geometry independent of the viewport size.

I think the center grip might be more useful for people who use AutoCAD for process diagrams or manufacturing drawings.

@Jeff_M  Looks like th tool doesn't support 2021 yet. I loaded it and it disabled the VP Grip. That doesn't matter since I'm not going to use it anyway.

Oh, yeah, I forgot that I had to edit the PackageContents.xml file to specify use with newer releases. There is a section that has SeriesMax, changing the existing value to 24.1 then allows it to work in C3D 2020 & 2021

This is the "as designed" behaviour when using the viewport grip. 

See this article - https://knowledge.autodesk.com/support/autocad/troubleshooting/caas/sfdcarticles/sfdcarticles/Viewpo...

I also use Blackbox's viewport grip tool to disable the central grip - such an annoying place for the grip - right in the middle of the viewport.

FWIW -

I just recently had a customer inquire about this. After investigating, Autodesk seems to have published the app updates without updating PackageContents.xml as they said they would in an email exchange from 2020-03-20. 

Autodesk has supposedly already corrected this for my live apps, so users need only update the app, if it's not working on any released versions that support Autoloader. 

Because of all of this they are being additionally mindful if/when Autodesk releases a future 2022 version, which my apps are also already compatible with (hypothetically, I cannot really confirm or deny). #NdaProblems

The root of all of this malarkey, is that Autodesk insists on modifying the app I upload to be whatever it is in the resultant download & install - what I publish as the developer is significantly simpler/smaller, only providing the essentials for the app to work - what they do unfortunately introduces all sorts of garbage, changes file/folder structure, etc and they refuse to simply publish what I upload (which works, as I use them for my own daily work).

HTH, Cheers
