Description

The Arch Fence is a object that builds a fence by repeating a single fence post and section along a given path.

Usage

Creating from scratch

  1. Use a workbench of your choice to create a single fence post and a single section.
  2. Create the path the fence should follow using the Sketcher Workbench or Draft Workbench.
  3. Switch back to the Arch Workbench.
  4. Select the section, post and path in exactly that order.
  5. Press the Arch Fence.svg Arch Fence button

Options

For now the tool assumes the following

  1. The Path is drawn on the XY-Plane
  2. Section and Post are drawn at the origin so that they stand upright in front view

Properties

Data

  • DataPath: The path the fence should follow
  • DataPost: A single fence post to repeat
  • DataSection: A single section to repeat
  • DataNumber Of Posts: The total number of posts used to build the fence. This is calculated automatically.
  • DataNumber Of Sections: The total number of sections used to build the fence. This is calculated automatically.

View

  • ViewUse Original Colors: When set to true the fence will use the colors from the original section and post. Otherwise the ShapeColor of the fence will be used to colorize the fence.

Notes

  • Arch Fence was introduced in FC v0.19 by user furti.
  • Forum thread discussing Arch Fence functionality

Scripting

The Fence tool can be used in macros and from the Python console by using the following function:

Fence = buildFence(section, post, path)

Example.

import FreeCAD
import Part
import Arch

parts = []

parts.append(Part.makeBox(2000, 50, 30, FreeCAD.Vector(0, 0, 1000 - 30)))
parts.append(Part.makeBox(2000, 50, 30))
parts.append(Part.makeBox(20, 20, 1000 - 60, FreeCAD.Vector(0, 15, 30)))
parts.append(Part.makeBox(20, 20, 1000 - 60, FreeCAD.Vector(1980, 15, 30)))

for i in range(8):
    parts.append(Part.makeBox(20, 20, 1000 - 60, FreeCAD.Vector((2000 / 9 * (i + 1)) - 10, 15, 30)))

Part.show(Part.makeCompound(parts), "Fence_section")
fence_section = FreeCAD.ActiveDocument.Fence_section

sketch = FreeCAD.ActiveDocument.addObject("Sketcher::SketchObject", "Path")
sketch.Placement = FreeCAD.Placement(FreeCAD.Vector(0, 0, 0), FreeCAD.Rotation(0, 0, 0, 1))
sketch.addGeometry(Part.LineSegment(FreeCAD.Vector(0, 0, 0), FreeCAD.Vector(20000, 0, 0)), False)
sketch.addGeometry(Part.LineSegment(FreeCAD.Vector(20000, 0, 0), FreeCAD.Vector(20000, 20000, 0)), False)

post = Part.makeBox(100, 100, 1000, FreeCAD.Vector(0, 0, 0))
Part.show(post, "Post")
post = FreeCAD.ActiveDocument.Post

Fence = Arch.buildFence(fence_section, post, sketch)
