Draw and edit a foam pattern

Create a cut outline, choose Vertex, Segment, or Spline editing, and promote a closed shape to foam.

These instructions are for Armorsmith Designer 2.1.1.0. Earlier versions, including 2.1.0.10, can show different panels and labels.

Draw the flat outline first, then refine it before giving it thickness. A simple bracer or trim panel is easier to edit when it uses only a few corners and curve changes.

Create and promote an outline

1. Open Workshop and select a workspace.
2. Open Create above the pattern view and choose Line, Rectangle, or Circle.
3. Complete the shape in the 2D view. For a free outline, place a few anchors and close the path when ready.
4. Select it and use Edit Shape for further changes.
5. When the outline is closed and encloses a valid area, right-click it and choose Promote To Foam Pattern.
6. Open Edit Foam to set thickness and forming.

Creating an outline alone does not make a solid foam piece. Open or self-crossing outlines cannot form a valid solid.

Choose what to edit

Edit Shape provides Vertex, Segment, and Spline selection levels, including grouped outlines.

In Workbench Edit, choose the appropriate selection level:

Selection	Use it for
Vertex	Anchors, handles, and individual corners.
Segment	A section of the outline between anchors.
Spline	The outline as a whole.

Tools change with the selection level. Select the intended target before applying an operation. Ctrl adds to selection. Use Done to finish editing.

Refine anchors and curves

Use Corner, Bezier, or Bezier Corner for the selected vertex. Straighten or curve the intended segment rather than adding extra anchors to approximate a curve. Add Point inserts a vertex on a segment without changing that curve. Delete Segment removes selected segments while keeping the remaining pieces.

Break separates a segment into independent endpoints and keeps Edit Shape active. Connect joins two open endpoints with a straight segment. Breaking or opening a foam outline can remove its solid preview until you close it again.

Trim, extend, or offset

• Trim removes a clicked portion between crossing paths. Provide a crossing boundary in the same workspace.
• Extend starts from an open endpoint and follows its tangent to a crossing path.
• Offset Outline… creates a separate outline at an entered distance in millimetres. Inspect tight or concave corners. If the offset collapses or crosses itself, reduce the distance; the original remains unchanged.

Press Escape to finish a click-based construction operation. Use Edit → Undo if the result is unsuitable.

Reuse a design

Right-click an outline for Create Instance or Create Mirrored Instance. Linked instances share outline edits but retain their own placement. Use Make Unique before making an outline change that should affect only one copy.

Enable Live Symmetry links the outline’s symmetric construction. Bake Symmetric Outline turns that relationship into a complete outline for independent editing. These commands differ from mirroring an attached part on the avatar.

Set physical dimensions

Select a supported rectangle, circle, or ellipse and use Inspect for Width/Height or Radius. Recheck layer containment after resizing a raised piece.

Keep the flat cut outline separate from the formed preview. A 2D corner chamfer changes the outline; Edge Finish changes the thickness edge in 3D.
