You can instruct ArtCAM to check for coincident nodes in a selection of open vectors, within a specified distance of one another, and vector intersections.
To identify the coincident nodes in your vector artwork:
- Select Edit > Select or click the Select
button. - Select the vectors you want to check with the Vector Doctor.
- Select Vector > Doctor or click the Vector Doctor
button. The Vector Doctor panel is displayed. - In the Identify Problems area, select Coincident points.
- If you only want ArtCAM to recognize nodes in the selected vector within a specific distance of one another as coincident, specify the distance in the Tolerance box.
- Click Identify. ArtCAM marks all coincident nodes in an individual vector with a red
icon. Any coincident nodes from different vectors are marked with a green 
icon. - Select Edit > Node Editing or click the Node Editing
button to manually fix any coincident nodes.
