In this session, we discussed techniques for enhancing CNC designs, including adding folded corners to 3D flags, optimizing rotary projects for tapered designs, and creating flat surfaces on curved models for engraving. Additional tips focused on toolpath selection and improving efficiency in 3D modeling workflows.

Key Tips Learned in this Q&A:

• Scaling Bitmap Images: Accurately resize bitmap images in Vectric by aligning known dimensions with the Scale tool and ensuring proper rotations for straight edges.
• Creating Flat Surfaces on Curved Models: Use Aspire’s modeling tools to generate flat or arched areas for engraving on 3D designs. Adjust combine modes and sculpting tools for seamless integration.
• Rotary Project Optimization: Add zero-plane components and adjust shape heights to prevent distorted patterns when wrapping models on a cylinder.
• Toolpath Selection: Use profile toolpaths with a V-bit for outlining designs without filling spaces, ideal for detailed carving.
• Engraving Alignment: Incorporate cross-section vectors and two-rail sweep tools in Aspire to create precisely aligned features on curved surfaces.
