This session explored techniques for VCarving inlays inside pockets, converting CRV files to STL, and cleaning up imported 3D STL files with severe drop-offs. We walked through Aspire's sculpting, fading, and two-rail sweep tools to refine STL art, and answered hardware-related questions like drawing tablets and RichAuto controller upgrades. We wrapped up with a discussion on creating bar rail moldings using the molding toolpath or custom tooling.

Key Tips Learned in this Q&A:

  • Carving in Pockets: To carve inlays at the bottom of a pocket, reset your Z-zero inside the pocket and carve as if it’s the new material surface.

  • CRV to STL Export: You can’t export a full CRV file to STL—export only the 3D components using Aspire’s “Export as 3D model” tool in the Design tab.

  • 3D STL Cleanup: Use the Sculpt tool with preserve transparency OFF to pull out stretched pixels, then fade and trim to control edges and improve blend into backgrounds.

  • Drawing Tablets in Aspire: Wacom and other tablets (like Xencelabs) work great with Aspire. Enable them via Edit → Options → “Use a graphic tablet.”

  • Bar Rails: Bar rails can be machined with molding toolpaths or a large custom bit. Double-sided machining is an option but takes setup; Pete shared his approach using molding toolpaths.

  • 00:43:15 – How can I model or machine bar rail corners using Aspire or CNC?

  • 00:46:35 – What’s the difference between “gap” and “offset” in copy array?
