You do not show how you get `layr`, so its impossible for anyone to answer this question. My immediate thoughts are maybe you have grabbed a group layer ... ... View more

Isn't what you are describing simply a buffer around a line? In the buffer tool you can get the buffer distance from a field which could hold your pre-computed distance. Suggest you check out the help file on the buffer tool. ... View more

Also as a test, if your map has a basemap in it, try removing that to see if performance improves. I'm seeing issues with 10.8 with basemaps, they lag horribly, similar to what you describe. I find removing the basemap significantly improves things. Leads me to think it is a graphic driver issue. ... View more

I'm using 10.8 at work and I have noticed issues when a basemap is being displayed. I also have a new laptop. It doesn't crash but it does lag horribly and this is on a brand spanking new i7 with a rtx graphic card. So either its a driver card issue or esri are throttling base map access to arcmap, is what I feel. I suspect it's more of an issue with hardware, even though ArcMap is a great piece of software, its 32 bit and old and is slowly being broken by office updates. Time to move on to ArcPro... which by the way also breaks with every Office 365 update.... 😵 ... View more

Here is some sample data, note 2 points are selected: DuncanHornby_0-1673027089220.png Here is the sub-model (This I called Select Model), with a single selection exist tool: DuncanHornby_1-1673027198644.png   Here is the master model: DuncanHornby_2-1673027262015.png If a selection exists as determined by the sub-model (Select Model) then buffer the selection, else do a selection based upon ID. All logic ran as expected, may be you were not exposing the parameters of the sub-model as Parameters (those P's)? ... View more

It's not entirely clear what it you are doing, you say "Is it possible to generate two duplicate watershed feature class using the same pourpoint?". This sounds like you want to run the tool twice or simply call the Copy Features tool? Then you go on to show an update cursor which seems to have nothing to do with generating watersheds... ...

Here is a snippet to get you going:   class ToolValidator: # Class to add custom behavior and properties to the tool and tool parameters. def __init__(self): # set self.params for use in other function self.params = arcpy.GetParameterInfo() def initializeParameters(self): # Customize parameter properties. # This gets called when the tool is opened. self.params[2].value = "Regular" return def updateParameters(self): # Modify parameter values and properties. # This gets called each time a parameter is modified, before # standard validation. if self.params[2].value == "Regular": self.params[3].enabled = False self.params[4].enabled = True self.params[5].enabled = False elif self.params[2].value == "Randomly": self.params[3].enabled = True self.params[4].enabled = False self.params[5].enabled = True return def updateMessages(self): # Customize messages for the parameters. # This gets called after standard validation.     params[2] is a text parameter with string filter listing only regular or randomly, when you change it on the interface it show/hides parameters 3 or 4.  ...

A solution to your dilemma is to have a drop-down with the options "Current" and "other". If they select current then you use the code I had linked to. If other then that enables another parameter which offers up your File parameter. You do all that in the validation code section of your script tool. Enabling/disabling a parameter has the affect of show/hide the parameter. ... View more

The error message in your screen shot says you can't add anything if you have a basic license. Have you updated ArcMap recently and its defaulted back to basic license for some reason? Is it a new installation on a new PC and whoever did that gave you a basic license?  Are these geodatabases provided to you and they have stuck something in the feature dataset that is incompatible with your license level? Finally after making a backup of the geodatabase, try running compact tool on it, this may resolve the issue identified by @Anonymous User. ... View more
