How to use the prism toolpath in Vectric software | 2.5D Toolpaths

Overview

The Prism Carving toolpath creates a raised, beveled prism shape on selected closed vectors using an angled tool, producing a hand-carved effect. This video demonstrates how to set it up in Vectric Aspire, including depth calculation, tool selection, and previewing the result.

Steps

1. Select a closed vector in the drawing.
2. Go to the Toolpath Operations section in the Toolpath tab and choose Prism Carving.
3. Set the Start Depth – the depth from the top of the material where the toolpath begins.
4. Set the Prism Depth – the height of the prism.
   • Use Set Depth for Full Prism to calculate the maximum prism depth based on the shortest distance between vectors.
5. Choose an angled tool, e.g., a 9-degree V-bit.
6. Select the Cut Direction: Climb or Conventional.
7. If multiple letters/shapes exist, set the cut order.
8. Optionally use the Vector Selector to choose specific vectors or layers for this toolpath.
9. Name the toolpath and click Calculate.
10. Preview the visible toolpath to verify the result.

Key Points / Warnings

• Prism Carving is often used on lettering and is frequently paired with a Profile or Pocket toolpath to cut vertical edges or clear material between shapes.
• Using a prism depth smaller than the calculated full prism depth will leave flat areas on top of the prism.
• The full prism depth is determined by the shortest distance between vectors; entering a larger value is not possible without producing unwanted geometry.
• A dedicated V-bit or angled tool is required for the raised bevel effect.
