Hello, The Tool coumentation mentiones that only three types of shape are supported:* Line * Rectangle * Circle What about Point or Polygon gemetries? Is there any implicit or explicit way to get them? Thanks, Szymon Piskula

nav[aria-label="Primary Navigation"] { padding: 0; & ul { list-style: none; width: 100%; display: flex; flex-direction: row; justify-content: start; align-items: start; gap: 30px; padding: 0; & li { margin: 0; } & ul li { list-style: none; } } }

Python Tool class supported geometries

Hello,

The Tool coumentation mentiones that only three types of shape are supported:

Line
Rectangle
Circle

What about Point or Polygon gemetries? Is there any implicit or explicit way to get them?

Thanks,
Szymon Piskula

It's just a Polyline object.

I just realized that after I found the documentation. Thanks!

Does anyone know where we can get documention for the line_geometry object that onLine produces?

I am trying to simply create a line with onLine and turn it into a polyline.

Hi Szymon,

There is no specific shape for point or polygon.

To construct the point, you must use onMouseDown or onMouseDownMap. Using the x and y coordindates you can construct the point geometry.
pt_geom = arcpy.PointGeometry(arcpy.Point(x, y))
For polygon, we hope to include this for final. For now, you would need to use line and close it off. Here is an example:
class LineToPolyTool(object):
    """Implementation for LineToPoly_addin.linetopoly (Tool)"""
    def __init__(self):
        self.enabled = True
        self.cursor = 3
        self.shape = "Line"

    def onLine(self, line_geometry):
        array = arcpy.Array()
        part = line_geometry.getPart(0)
        for pt in part:
            print pt.X, pt.Y
            array.add(pt)
        array.add(line_geometry.firstPoint)
        polygon = arcpy.Polygon(array)
I hope this is helpful.

could you throw your code within the code blocks in the HTML editor (ie # symbol after selecting your code)
