County lines and geographic projects

as requested on support…

Given a State map which has the county lines as open vectors:

How to cut the lines?

​One possible approach would be to export to an SVG, open the SVG in a suitable tool, apply a stroke to the open lines, then instantiate the strokes (creating closed regions), then Boolean union the geometry, resolve how it interacts with the outline of the State, and then cut as a V carving toolpath.

Alternately, one may simply assign a “No Offset” Contour toolpath…

This is easily done by selecting all open vectors:

which may then be grouped for convience:

A Contour toolpath may then be assigned:

The text of course may be cut with a V carving toolpath:

One way to handle the state outline would be to add a rectangle:

and cut as an Advanced V carving:

(being careful to include the Barrier Islands)

which has one slight difficulty — the text labeling one county is then cut away (also the arrow isn’t drawn well) — resolving that requires a bit of drawing work…

Zooming in we have:

Offsetting around the text:

which with a bit of cleaning up via Node Editing:

seems reasonable

It will also be necessary to ensure the area around the arrow is not cut away — drawing in a circle:

and adding another:

allows us to connect them with straight lines:

and closing this:

allows using Trim Vectors:

which may then be closed using Joint Vectors:

and re-positioned a bit:

and things cleaned up a bit:

and then inset:

and then the shapes merged with the outline of the state using Trim Vectors:

OK

OK

and then closed using Join Vectors:

Repeat for any other instances:

Add the inset arrows to the V carving of the text:

Then update the outlines for the Advanced V carving:

to arrive at:
