Hi All!
I'm currently working on a script that can automate basic map production for my organisation.
The current part I'm stuck on is, I have bookmarks that the user can select from a pre-defined list, although if the area they want to look at isn't in that list they could enter the extent themselves and set the scale. Although, currently if they select a bookmark and leave the extent part blank it throws an error as nothing has been entered for extent even though I have set it to be an optional parameter.
Is there a way I can calculate the extent if the user selects a bookmark so they can be in the same tool, while allowing the user to manually enter the extent if needed?
Below is my current code:
import arcpy
arcpy.env.overwriteOutput = True
workspace = arcpy.GetParameterAsText(0)
aprx = arcpy.mp.ArcGISProject('CURRENT')
lyt = aprx.listLayouts(Product_Size)[0]
aprxMap = aprx.listMaps('Map')[0]
mf = lyt.listElements('MAPFRAME_ELEMENT', 'Map Frame')[0]
in_bookmark = arcpy.GetParameterAsText(1)
bookmark = mf.map.listBookmarks()
# Loop to zoom if user selects bookmark
for bkmk in bookmark:
if bkmk.name == in_bookmark:
mf.zoomToBookmark(bkmk)
arcpy.AddMessage(f'{in_bookmark} bookmark set')
else:
continue
extent = arcpy.GetParameterAsText(2)
arcpy.env.extent = extent
mf.camera.setExtent(arcpy.env.extent)
I think my issue is I'm still not understanding how exactly extent works in arcpy, but reading the documentation hasn't been much help so far. I would really appreciate some help or a nice gentle nudge in the right direction. If more of the overall code would be useful to see, let me know!
Thank you!
