How To Manually Find and Fix Vector Issues Without Using Vector Doctor

Overview

While Carveco's Vector Doctor is a powerful tool, sometimes you may want or need to manually locate problems in your vectors — especially if Vector Doctor misses them. This tutorial demonstrates how to use toolpath previews and node editing to isolate and fix open vectors, intersections, or loops without relying on automated checks.

Step 1: Try to Machine the Full Design

Select all the vectors and attempt to generate a toolpath (e.g. V-bit Carving).
If you receive an error such as Vector Intersections or Open Vectors, you know something needs fixing.

Step 2: Break Down the Problem

Select your vectors in smaller chunks — start with sentences, words, or decorative elements.
Attempt to refresh or calculate a toolpath for each smaller group.
When the error returns, isolate even further — down to individual letters or elements.

Tip: Use this method as a process of elimination to identify exactly where the problematic geometry lies.

Step 3: Zoom In and Inspect

Once you've narrowed down the issue to a specific shape or letter:

Zoom in to visually inspect overlaps, self-intersections, or disconnected points.
Look for stray loops or tangents that shouldn't be there.

Step 4: Use Node Editing to Fix the Issue

Select the vector and enter Node Editing mode.
Use the C key on a segment to create and then cut a node.
Delete unwanted portions or overlap segments manually.
Use Close Vector with a Line to reconnect paths if needed.

Advanced: You can also repair shapes by inserting new line or curve segments and manually joining them to adjacent nodes.

Step 5: Refresh and Recalculate

Once the issue is resolved:

Select the fixed vector(s).
Click Refresh in the toolpath menu.
Check for errors. If none, click Calculate.

Example: Overlapping Flourishes

For complex decorative elements like flourishes, use the same strategy:

Test in small groups.
Use Node Editing to visually check and correct overlapping nodes.
Simply moving a point out of intersection can solve the issue.

Final Simulation

Always simulate the final toolpath to check that all vectors carve correctly. Some open vectors won't cause a toolpath error but will still affect the result — e.g. missing V-bit engraving in closed shapes.

Note: Carveco won’t always throw an error for open vectors — so simulate everything to confirm it matches your design intent.

Summary

Summary:
You don’t always need Vector Doctor to fix machining problems. Break the design into manageable parts, isolate the problem area, inspect and fix it using node editing, then refresh and simulate. This manual method gives you full control over your artwork integrity.
