Not enough information. But probably because it's a section view and scale is set by the view it was created from. Right click the view and turn off "maintain alignment".
As this is a section view I'm guessing you need to break its alignment with the parent view.
Easiest way is to hold the Alt key and drag the the section view out of alignment.
Other way is RMB on the section view and uncheck Maintain Alignment.
@beachcomber, didn't know about the alt-drag thing.
This is worth a look -
If others new to SE find this thread, many want want to know that the general sheet scale is set by the first model view inserted on the sheet. Sometimes I even place the first view off to the side just for control over the displayed scale.
I now always place the first view of an entire draft off to the side to never lose reference to R1 for annotation control, thats unrelated to scale, but uses the same solution.
@12GAGE "the general sheet scale is set by the first model view inserted on the sheet."
I don't find that to be the case. When you do principal views off the first view, yes. But on my system view wizard always uses "best fit" at which point I either hit the "set view scale" button to the current setting or put in the scale.
Is there a way to turn off the "best fit" default?
I didn't think much about it, but I'm using this to display the sheet scale in my title block
It takes it's value for the first view on the sheet
