Arcpy Layer class minScale

What is the syntax to retrieve all layers' set minimum scale ?

not sure what you mean beyond it returning a double (number). Are you wanting to cycle through all the layers and return the minScale for each? Did you try something and it didn't work?

I haven't tried anything yet and yes you are correct as I did not have any luck searching the internet to achieve this.

The arcpy help is your best bet... this is the layer section

and from there, nothing too exciting ... maybe... mylayer.minScale if it is property

minScale

(Read and Write)

Provides the ability to set or get the layer's minimum scale threshold.

Double

As for arcpy.... bookmark the start of its menu tree... Arcpy ... , Dr Google isn't very good at tracking down all the properties and methods

I know that it can be done, documentation is lacking.

Try:

mxd = arcpy.mapping.MapDocument("CURRENT")

for lyr in arcpy.mapping.ListLayers(mxd):
    # to read minScale
    print lyr.minScale
    # to set minScale
    lyr.minScale = 500.0

Perfect, I arrived at the same.

Make sense, set the mxd and loop layers.

I will add this to an existing script that write data to csv.

Thanks

for layer in layers:
                    if layer.isFeatureLayer:
                        lyr_source = layer.dataSource
                        lyr_name = layer.name.encode("utf8", "replace")
                        print fullpath + " " + lyr_source + " " + str(layer.minScale)
                        scale = [layer.minScale]

                        # Write to Excel
                        b = fullpath.split('\\') + lyr_source.split('\\') + scale
                        writer.writerow(b)‍‍‍‍‍‍‍‍‍‍

Thanks, everyone I arrived at my final solution.
