See also Graphic Buffer tool. It can make a square buffer around points if you use square cap property. https://pro.arcgis.com/en/pro-app/latest/tool-reference/analysis/graphic-buffer.htm ... View more

There is also Graphics Buffer Tool. With the option Caps = square it will generate squares around points. You can also use it to make squared buffer around lines and polygons. ... View more

If this is needed for the visualization purposes then you probably could achieve a "dissolved" look by selection of a proper symbol. Make a symbol that has the fill layer first and the stroke second. Then enable the Symbol Level Drawing. This will ensure that the internal outlines are hidden by the fill. ... View more

> Isn't an Esri polygon invalid if one of the parts is invalid by itself? What is a part in the Esri polygon if the Esri polygon is a collection of rings? If you would make a separate polygon from each ring, the polygons that were made from the holes would be invalid, because they would have incorrect orientation. ... View more

For an Esri polygon to be simple, all intersections have to occur at vertices. In general, it follows from "a valid Esri polygon must have such structure that the interior of the polygon can always be unambiguously determined to be to the right of every segment", that: segments can touch other segments only at the end points, segments have non-zero length, outer rings are clockwise and holes are counterclockwise, each polygon ring has non-zero area. order of the rings does not matter, rings can be self-tangent, rings can not overlap. When you throw in the three rings together, the case when the un-rotated square ring has no vertex at the common point of the diamond shapes is a violation of "segments can touch other segments only at the end points". This is also not allowed by the OGC standard. ... View more

Note that the WKT geometry format stores Open Geospatial Consortium (OGC) geometry types. The ArcGIS Polygon geometry type is defined as a collection of rings. Exterior rings are clockwise, and holes are counterclockwise, there can be no self-intersections. In a most basic way, a valid Esri polygon must have such structure that the interior of the polygon can always be unambiguously determined to be to the right of every segment. This definition is also enough to represent any polygonal structure that OGC MULTIPOLYGON can represent. OGC standard definition is more complicated than Esri's. It has a MULTIPOLYGON type that is a collection of POLYGON types, and a POLYGON type consists of one exterior ring and zero or more holes. The OGC POLYGON interior must be topologically path-connected, that is it should be possible to trace a continuous path between any two interior points of a single OGC POLYGON without touching the boundary. When WKT definition in question is converted to Esri polygon, it becomes an Esri polygon that has three rings. These three rings have proper orientation and have no self-intersections, the resulting Esri polygon is simple from the point of view of Esri features. Therefore check geometry will not flag it. There are other cases when OGC standard is more restrictive than Esri simple polygon. For example, cases when a ring is self-tangent are not allowed by OGC standard, but are perfectly valid for Esri features. To address the differences there is the OGC option in the Repair Geometry and Check Geometry tools available in ArcGIS Pro. This option was introduced specifically to allow validation and repair of features so that they can be exported into valid OGC shapes. The tool will ensure that the Esri polygon rings are sorted such that it is easy to separate them into OGC POLYGON groups, and also it ensures that the whole structure, when converted to OGC MULTIPOLYGON, is OGC simple. ...
