🔧 CNC-Ready Drawings in AutoCAD — Perfect Notches with AutoLISP

Most CNC problems don’t start at the machine —
they start with improper CAD preparation.

If your wood-carving drawings contain long polylines, overlaps, duplicates, or wrongly closed paths, the CAM software will generate wrong toolpaths, double cuts, and wasted material. This is exactly where our AutoLISP-based Notch Creation Solution comes in.

🪵 Why Notches Matter in CNC Wood Carving

In CNC machining, geometry behavior is critical:

  • Closed paths are treated as profile cuts

  • Open paths are treated as engraving paths

  • A single continuous engraving vector must be an open polyline

To control tool entry and exit points, notches are essential.
Manually creating them is slow, inconsistent, and error-prone — especially on complex artwork.

Our AutoLISP solution automates this entire process.

🛠️ Clean & CNC-Friendly CAD Workflow (As Shown in the Video)

  1. Clean the Drawing Instantly

    Start with OVERKILL:

    • Removes duplicate objects

    • Eliminates overlaps and tiny fragments

    • Merges broken segments into clean, continuous geometry

      • With Optimize segments within tolerance enabled, your drawing becomes CNC-ready in seconds.
  2. Make Geometry Explicit

    Use EXPLODE where required:

    • Converts heavy polylines into simple lines and arcs

    • Improves CAM predictability

    • Ensures precise machining behavior

  3. Load the Wood Carving Utility Pack

    Using APPLOAD, load:

    Wood_Carving.FAS

    This utility pack includes four powerful AutoLISP programs:

    • Intr_Notch

    • WD

    • Ply

    • UB

⚙️ Automated Notch Creation & Boundary Control

🔹 Intr_Notch — Insert Notches Automatically

  • Specify notch width

  • Specify number of notches per side

  • Select lines and arcs

✔ Notches are inserted instantly
✔ Full control over tool entry and exit points

🔹 WD — Generate Boundary with Notches

  • Enter horizontal margin

  • Enter vertical margin

  • Enter notch width

✔ Creates a clean outline
✔ Includes perfectly placed notches

🔹 Ply — Boundary Based on Ply Size

  • Enter ply width

  • Enter ply height

  • Enter notch width

✔ Boundary is sized exactly to the ply
✔ Notches are inserted automatically

🔹 UB — Undo Without Losing Work

  • No need for multiple UNDOs

  • Type UB

  • Instantly reverses the last AutoLISP operation

✔ Faster corrections
✔ Zero accidental data loss

✅ Recommended CNC Preparation Workflow

  1. Run OVERKILL

  2. Explode where required

  3. Insert Notches

  4. Generate the Boundary

  • Prevents incorrect toolpaths

  • Avoids double cutting

  • Saves material

  • Reduces machining errors
