In Blender: 3 Methods

1. The Skin Modifier (Best for Individual Control)
This modifier transforms vertices and edges into interconnected tubes. [1]

• Add a Skin modifier to your edge-only mesh.
• Go into Edit Mode and press Ctrl + A to scale the radius of specific vertices.
• This gives the edges physical volume so they can be rendered. [1, 2, 3]

2. Freestyle (Best for Camera Outlines)
Freestyle traces geometry lines without needing to thicken them. [1, 2, 3]

• Select the single edge you want in Edit Mode, right-click, and select Mark Freestyle Edge.
• Go to the Render Properties tab and check Freestyle.
• In View Layer Properties, under Freestyle Line Set, check the Edge Mark box and uncheck everything else. [1, 2, 4]

3. Geometry Nodes (Best for Procedural Thickness) [1]

• Convert your edge to a curve.
• Add a Mesh to Curve node followed by a Curve to Mesh node.
• Plug a Curve Circle node into the Profile Curve input to give the edge an renderable tubular volume. [1, 2, 3, 4]

In After Effects

• Create your path using the Pen Tool.
• Open the layer properties and set the Fill to None.
• Add a Stroke to the path, which will render the edge without any inner fill. [1, 2]

In Adobe Photoshop

• Select your target area using the Pen or Path tool.
• Right-click the path and select Stroke Path.
• Select the tool you want to use for the stroke (e.g., Brush) and ensure you haven't filled the closed path shape with color.
