I have a question regarding generating tessellated hexagon grids in ArcGIS Pro: How do I define the length of the side of the hexagon bins that are generated (e.g. 20m sides)? There doesn't seem to be a parameter for that in the tool setup.
For reference, I am using this tool: https://pro.arcgis.com/en/pro-app/latest/tool-reference/data-management/generatetesellation.htm
Solved! Go to Solution.
This is a job for the Calculate Value tool in ModelBuilder! Create a Model variable Side of type Double, insert the Calculate Value tool and use this expression:
(%Side%)**2 * (3 * (3**0.5))/2
Set Output Type to Double and connect it to the Generate Tessellation tool!
the key is the root 3 / 2 . It can be related to the maximal radius R and the minimal radius 'r' depending on which type of hexagon you are creating See the image on the page and decide which radius you need
