create one big island from many small

[mig]

  Hello .

 Sorry guys for stupid question .

 I guess was some option to create one big island   geometry from   many small islands.

Is it true ?   Any idea ?

  Thank you in advance

Got a sketch or something to go by?

Surface High-Speed Waterline. Create a 0.0002 diameter tool.

Set min/max depth to the same absolute value, to generate a single pass in XY.

Use the "skip pockets smaller than" option to keep the tool from going in-between the islands. Or use a containment boundary to keep the tool outside the other islands.

The path will cut around all the island geometry. 

Backplot and save the geometry to a level.
