I am looking for a way to Query Current Scale.
My intention is to only have a feature class loaded one time into an MXD and turn features on and off based on current scale.
Example.
I have transformers. I don't want all the transformers visible at a township level. I want some visible at the Section level, more visible at a quarter section level and all of them visible at a quarter quarter section level.
Currently I have Transformers as a feature 4 times and use definition queries to determine detail level (i.e. Twp, Sec, QS,QQS) and set the scale range to turn them on and off.
Ideally, I would like to query current scale to set the definition query.
Example
The current scale in scale window is 1:24,000 I would set up a column (call is scale_reference) with the desired scale at which this feature will be visible.
something like this in the definition query: [Scale_reference] > current_scale
this way only township level transformers that I want to be visible when I am zoomed out beyond 1:24,000 will be visible. When I zoom into 1:12,000 than all transformers that have a reference_scale of greater than 11,999 will be visible etc.
