Using block subdivisions from Street graphs on my own polygons/road networks

Hi

I need to model massing scenarios for city development.
I have big lots to work with that I need to split into smaller parcels for later building extrusion.

When using street graphs tool the blocks are created automatically and there are several subdivision options - recursive, skeleton etc.

Is it possible to apply those subdivisions to my lots without tracing roads manually?

in other words - can I apply subdivisions to an imported polygon?

thanks!

PS: I saw many questions touching on parcel splitting code - has ESRI released anything on this topic?

Definitely. You can apply the same subdivision modifier on your imported shapes.

Select the desired shape and then menu Shape > Subdivide.

Regarding parcel splitting code, you can play with splitAndSetbackPerimeter, setbackPerEdge, or the simple split operations. Not exactly the same outcome but you can get a lot of work done with these.

Hope this helps.
Cheers
