Bars on edges

Traces an edge with a row of bar supports. Use when the edge's side walls do not qualify as area clusters.

Previously called Edge with bar support

Definition of "edge" in the context of this support action

  • non-flat junction between two triangles
  • convex on the outside (diverging normal vectors)
  • angle between adjacent normals of 40° and more
  • visible in orthogonal -Z projection, ignoring self-occlusion

Part sections seen from the side. The top row shows edges supportable with this action, the bottom row shows edges ignored by it. Not shown: Angle minimum of 40° between normals of triangles along a qualifying edge.

General parameters

Parameter Description Notes
Description

Holds a text label for the action that remains visible even when the action parameters are collapsed in the script tab

Color

Sets a display color for the support elements generated by this action

Cannot be reverted once changed, only explicitly set to a new color

Maximum edge angle to XY-plane

Describes the maximum angle between an edge and the XY plane. If the maximum angle is exceeded, the edge is disregarded for applying supports.

0-90°

Neighbor area angle

Angle of triangles against the horizontal, along an edge, where (in Z) one of the triangles is below the edge. Edges where the lower triangle is angled against the horizontal shallower than this angle do receive edge support, too.

0-90°

Anchor distance

Sets the distance between two anchor points.

1-100 mm

Contour offset

Sets the distance between an anchor point and a clear area.

0-5 mm

Startpoint distance

Sets the border distance between the edge and the start of the support structure

0-5 mm

Z-range limitation

Even when an edge spans a greater height range than given by Minimum Z value and Maximum Z value, only those anchors sprout bars that lie within the values specified here.

Groups

Forms groups of bars for optional cross-bracing, bunching with a tapering envelope, and generating local baseplates

See Groups
Brace

Generates cross-bracing bars between bars in a group

See Brace
Support properties Bar

Parametrization for the shape of the bars generated for this support actions

See Bar support properties

Support properties Baseplate

Parametrization for the shape of local baseplates generated for grouped bars

See Support properties Baseplate

Groups

There is no explicit switch to turn grouping off. It is technically always active, but as long as no tapering, bracing, or generation of a local baseplate is specified, it has no effect.

Parameter Explanation Notes
Bars per group

Bunches at most this many bars into a group. A group of bars may receive braces, may have a local baseplate, and the group as a whole may be tapered.

Group taper

Controls the taper of a group of bars

  • -100 %: Bars are spread and splayed out
  • 0 %: No taper at all
  • 100 %: All bars in a group converge in a single point

Unavailable while Bars per group is <2 or Number of legs is >0

Baseplate for group

Adds a local baseplate to a group's contact point or patch on the platform

Unavailable while Number of legs is >0

Pad height, Contour offset, Taper angle, or their equivalents, have been moved to the separate Support properties Baseplate section.

Brace

Parameter Explanation Notes
Brace

Arrangement and orientation of the cross-bracing bars given by the capital letters resembling the shape

  • None or K, X, or N
  • Choice of None deactivates all other Brace parameters
Links per bar

A bar in a group may be linked to up to this many other bars by cross-bracing

Link angle

Lowest angle against the horizontal for the cross-bracing bars

  • 10° to 80°
Junction shape

Adapts or overrides the type of junction that the cross-bracing bars use to transition into the bars they connect between. For example, while the main bar may prescribe a straight connection in Support properties, any connecting bars generated out of bracing could still have straight connections.

  • Any: The main bar(s) may have this set to a specific value for any bars attached to it which may inherit or override that shape for their respective connection.
  • Straight: No curvature
  • Curved: Uses a smooth curve to transition gradually into the vertical bar.

Support properties Baseplate

These local baseplates generate for groups of bars when Groups > Baseplate for group is set to Yes. These baseplates are distinct from Support properties Bar > Pad on platform.

Parameter Explanation Notes
Outer offset

Distance by which the minimum contour formed by the contact points of a group's bars is extended to make the base plate's contour. This is the minimum distance before tapering.

For the Pattern of Point connection net, no offset is generated. Instead this value is used to derive the wall thickness of the point connections, using effectively twice this value.

Maximum height

The base plate's thickness

Taper angle

Applies a taper to the base plate's circumference. Positive angles taper the plate towards the top. Tapering only ever adds onto the contour offset.

  • -60° to 60°
Pattern

A selection of structures applicable to the baseplate

  • Solid: No structure at all
  • Rectangular: Square holes
  • Hexagonal: Hexagonal holes
  • Circular: Circular holes
  • Column: Circular columns
  • Point connection net: Attempts triangulation between the anchors on platform to ensure bars always terminate on solid plate volume without needing to make the entire plate solid
Cell size

Size of the holes for Rectangular and Hexagonal, measured at right angles between wall surfaces, or outer diameter for Circular and Column, respectively

Rectangular, Hexagonal, Circular, Column only

Pattern wall thickness

Thickness of walls between holes, or gap between columns

  • Generates open supports for single beam passes when set to 0, closed or solid supports for contour-and-hatch exposure otherwise
  • Must be >0 for Circular and Column
  • Rectangular, Hexagonal, Circular, Column only
Perimeter wall thickness

Generates a wall along the perimeter of this thickness

  • Generates open supports for single-pass beam exposure when set to 0, closed or solid supports for contour-and-hatch exposure otherwise
  • Rectangular, Hexagonal, Circular, Column only
  • Ignored when Perimeter wall thickness is >0
Polygon corner

Affects triangle resolution of the circular features

Circular, Column only
Minimum pattern area

A filter to help suppress fragments. Holes are suppressed (filled) if area cannot meet minimum fraction

  • Rectangular, Hexagonal, Circular, Column only (ignored for Column)
  • Unavailable when Pattern wall thickness is 0
Minimum structure hatch

A filter to suppress any polygon stretches shorter along the XY plane than the given value.

  • Rectangular, Hexagonal, Circular, Column only (ignored for Column)
  • Unavailable when Pattern wall thickness is >0
