Because your height attribute is a floating point number and doing calculations on floating point numbers in the binary system  is imprecise.   If you want further information why this is the case, here are two good starting points: https://stackoverflow.com/questions/588004/is-floating-point-math-broken https://stackoverflow.com/questions/21895756/why-are-floating-point-numbers-inaccurate   ...

Select Layer By Attribute will be very slow for that many features.   You could use your query to make a new layer with Make Feature Layer. This layer will contain only features that you want to delete, so just select them all and delete.   Or you could d o it with a little Python script: layer = "LayerName" query = "SomeField = 'DELETE ME'" with arcpy.da.UpdateCursor(layer, ["OID@"], query) as cursor: for row in cursor: cursor.deleteRow()   These will edit your shapefile, so make a backup! ...

Here's one way to do it: Copy/paste the script into your ArcGIS Pro Python Window and execute. This will define a function 'straighten_points'. import numpy def straighten_points(layer, fit_degree=1): """Snaps all (selected) points in a layer to a regression line. This edits the input layer! layer: layer name (str) or layer object (arcpy.mp.Layer) fit_degree (int): degree of the polynomal fit, defaults to 1 (linear regression) """ sr = arcpy.Describe(layer).spatialReference # extract point coordinates points = [r[0].firstPoint for r in arcpy.da.SearchCursor(layer, ["SHAPE@"])] x = [p.X for p in points] y = [p.Y for p in points] # polynomial fit coef = numpy.polyfit(x, y, fit_degree) polynom = numpy.poly1d(coef) # construct fit line geometry fit_xy = [ [x_, polynom(x_)] for x_ in numpy.linspace(min(x) - 1000, max(x) + 1000, 100) ] fit_points = [arcpy.Point(fx, fy) for fx, fy in fit_xy] line = arcpy.Polyline(arcpy.Array(fit_points), spatial_reference=sr) # snap points to regression line geometry and update layer with arcpy.da.UpdateCursor(layer, ["SHAPE@"]) as cursor: for p, in cursor: new_p = line.snapToLine(p) cursor.updateRow([new_p])   Select the points you want to straighten   Run the function. Using 1 does a linear regression, which should be fine for straight road segments. For curves, you could try 2 or higher degrees, but remember that using this function will edit the layer, so make a backup. straighten_points("NameOfYourLayer", 1)     Before:     After (northern road: fit_degree = 1, southern road: fit_degree = 2:   ...

As Dan said, you could set it to Derived, that will show the "No parameters" message. Alternatively, you can just reset the parameter's value in the updateParameters() method: class Tool(object): def __init__(self): self.label = "Tool" self.description = "" self.canRunInBackground = False def getParameterInfo(self): return [ arcpy.Parameter(name="code", displayName="Land Use Code", datatype="GPString", parameterType="Required", direction="Input") ] def updateParameters(self, parameters): parameters[0].value = "9999 - Not Classifiable" def updateMessages(self, parameters): parameters[0].setWarningMessage("This parameter is for information only, you can't edit it.") def execute(self, parameters, messages): return ...

There doesn't seem to be an option to specify the breakpoint for switching between the views. But you can modify your dashboard link to always open a specific view: https://doc.arcgis.com/en/dashboards/latest/create-and-share/url-parameters.htm Dashboard view parameters When a dashboard opens, the optimal view of the dashboard automatically loads. If you have created a mobile view for your dashboard, that view loads when opened on mobile devices. When opened on a desktop, the desktop view loads. You can change the view by adding the appropriate dashboard view parameter to your dashboard's URL. The view=mobile parameter loads the mobile view. The view=desktop parameter loads the desktop view. ... View more
