How does the Offset Vectors tool work in VCarve Pro & Aspire: inward and outward offsets, sharp corners, and the top 5 expert tips?

Overview
Offset Vectors creates new vector shapes that are parallel copies of the selected vectors, shifted by a distance you enter. It is one of the most-used tools in the software: toolpath boundaries, border frames, V-carve prep outlines, inlay allowances and shadow effects all start with an offset. It works on open or closed vectors.
Basic Workflow
- Select one or more vectors (open or closed).
- Open Offset Vectors (Drawing tab).
- Choose the direction: Outwards / Right or Inwards / Left.
- Enter the Distance.
- Tick Create sharp offset corners if sharp corners in the design should stay sharp.
- Click Offset to create the new vector.
The offset creates NEW vector shapes. Select the newest vector and offset again to build concentric rings. You can offset several vectors at once; each offsets independently.
Corners: the "Create sharp offset corners" option
This is the only corner control on the form. When it is ticked, sharp corners in the design are retained in the offset (the documentation shows the same shape offset with the option on and off side by side).
Use it for: geometric shapes where you want true mitered corners, such as rectangular frames and clean V-carve outlines.
Leave it off for: decorative borders and organic shapes where a softer, flowing result is fine.
The sharp corner gotcha: when you offset a very acute angle with sharp corners ticked, the corner point can land a long way from the original shape. Check designs with narrow V-shapes after offsetting and delete the result if a spike appears.
Offset Direction for Open Vectors
For closed vectors (like a circle or rectangle), inward and outward are unambiguous. For OPEN vectors the choice is Right or Left of the vector's travel direction:
- Press N to enter Node Editing mode: a green node marks the START of the vector.
- Looking along the vector away from the green node gives the travel direction.
- Left is to the left as you look along that direction, Right is to the right.
Pro tip: If an open vector offsets to the wrong side, reverse its direction. In Node Editing mode, right-click a span and choose Reverse Direction.
Expert Offset Tips
Tip 1: Use a dedicated Offset layer
Before running an offset, create a new layer named "Offset" and make it active. That keeps offset vectors separate from your design vectors, so you can hide, lock or delete all offsets without touching the originals.
Tip 2: Use offset for V-carve boundary creation
V-carve toolpaths need a clean closed boundary. Offset outward from your design to make a boundary that sits clear of the letters, then use it as the V-carve boundary. Test the offset distance on scrap.
Tip 3: Multiple successive offsets for shadow effects
Offset, select the new vector, and offset again for evenly spaced concentric rings. A few rings at about 0.125 inch spacing makes a shadow-step effect around a logo or text that looks good as a V-carved decorative element.
Tip 4: Inward offset for V-carve text preparation
When V-carving wide letters, an inward offset of the letter outlines can serve as a pocket clearance boundary, removing material before the V-carve pass finishes the angled sides. Start with a small distance, such as 0.1 inch, and test on scrap.
Tip 5: Vector Boundary for multiple shapes
For a group of scattered shapes, Offset Vectors offsets EACH shape individually. The Vector Boundary tool (Drawing tab) draws one outline around all the selected vectors. Its Rubber Band Boundary option wraps a single outer boundary around everything, like a rubber band, and Offset Boundary pushes that outline out by a distance. This is useful for a single cutout boundary for a multi-element design without welding everything first.
Known Issue: Node Explosion
After offsetting, curves can come out as many short line segments (lots of nodes). Select the new vector and run Fit Curves to Vectors (Edit > Curve Fit Vectors, or the icon on the Drawing tab) to smooth it back into clean curves.
Common Use Cases
| Use Case | Offset Direction | Corners |
|---|---|---|
| Sign border frame (for example 0.5 inch outside the sign outline) | Outwards | Sharp ticked |
| V-carve clearance boundary | Outwards from letter outlines | Sharp off |
| Pocket inset (frame interior) | Inwards from border | Sharp ticked |
| Inlay allowance | Offset the male or female shape by a small amount; test the fit on scrap | Test on scrap |
| Profile clearance (cut path for on-line profiling) | Outwards by the tool radius | Test on scrap |
| Shadow step effect | Outwards, repeated | Sharp off |
| Safe area boundary | Inwards from the material edge | Sharp ticked |
Tight inside corners: an inward offset that is larger than the inside corner radii or the width of a narrow shape can collapse or give unexpected results. Reduce the distance and check the result.
