What it does

The add-in creates a closed boundary around selected curves at a specified offset distance and can combine multiple boundaries into one closed polyline. It supports lines, polylines, splines, arcs, circles, ellipses, and selected 3D curves, with results placed on the applicable XY plane. Open curves can be closed with straight or rounded end connections. Output options and settings include regions, asymmetric offsets, selection filtering, layer assignment, original-curve removal, and reusable zone styles.

Key capabilities

from the Autodesk App Store listing

Offset boundary creation

Builds a closed boundary around supported 2D and 3D curve types using a specified distance.

Boundary combination

Combines boundaries from multiple selected curves into one closed polyline.

Open curve closure

Closes open curves by joining the offset sides with either a straight segment or a curved connection.

XY plane projection

Projects 3D polylines, 3D splines, and other curves onto the relevant XY plane before creating the boundary.

Variable side offsets

Creates zones with different distances on each side, including a zone on only one side of the source curve.

Region output

Can produce the zone as a region rather than as polyline or spline geometry.

Selection filtering

Filters selected geometry so auxiliary items such as axes and dimensions can be excluded.

Preset zone styles

Stores up to nine zone styles for switching groups of settings.

Use cases

  • Creates boundary areas around pipe networks shown in flat water-pipe or gas-pipeline plans.
  • Creates a cutter-path sampling outline for CNC milling work.
  • Creates outlines for engraving on flat solid surfaces using a user coordinate system.

Who it's for

The add-in is intended for CNC milling technologists and people working with flat plans of pipe networks.

What the vendor says

«If you work with flat plans of water pipes, gas pipelines, and similar networks, then you probably have to solve the problem of constructing zone boundaries around this pipe. Typically, a pipeline is indicated by lines and curves. And there may be many more branches. It’s not difficult to make a couple of …»
