The start node in a vector determines the point at which a tool enters the block of material when you are machining a model.
You can change the position of the start node in any vector. The green node within a selected vector identifies the start node.
To change the position of the start node:
- Select
Vector > Node Editing or click the
Node Editing
button.
- Select the vector that contains the start node whose position you want to change. The selected vector is surrounded by a bounding box, within which you can see the spans, nodes and control points.
- Position the cursor over the node that you want to set as the start node. When the cursor changes from
to 
, right-click to display its context menu. - Select Start Node to set the start node. The selected node changes green.
When using a toolpath preview in the 2D view, you can also set the position of the start node in any toolpath containing a profile pass.
