## 6.4 Tools for Vector Layers

### 6.4.1 Edit Vector Points

You can edit an existing vector layer with this tool.

If you select a curve point, two additional control points appear. By moving these control points, you can change the shape of the curve. Normally the two control points are moved symmetrically. Holding a modifier key changes this behaviour:

- Alt key
The corresponding control point will nor be changed.
- Ctrl key (Windows), Command key (Mac OS)
The distance of the corresponding control point will be adjusted to the distance of the currently edited one.
- Shift key
The control point can only be moved along the original direction.

By holding Alt and clicking a vector point the whole subpath will be selected.

Double clicking on the path inserts a new point at the click position.

If you double click an already selected vector point, its position can be modified numerically.

If the fill or line color of the active vector layer is a gradient, this gradient can be edited directly in the document:

- Clicking and dragging moves a gradient color.
- By clicking on the gradient line a new color is created.
- Dragging a color away deletes that color. But note, that there have to be at least two colors in the gradient.
- The context menu of the gradient line allows to modify the gradient type and the color space.

The Tool Settings offer a way to invert the direction of a subpath by using Invert Direction of Subpath. It will change the direction of all subpaths containing selected vector points. This may be important when using the fill mode "Non-Zero-Winding-Number" (see chapter 4.5.4.4) or when creating 3D Bodies with a hole (see chapter 7.8.58).

Edit Vector Points uses the following mouse cursor shapes:

By clicking and dragging a selection rectangle will be created. Without a modifier key all vector points will be deselected and all points in the rectangle will be selected. If Shift is held, the state of the points in the rectangle will be switching.

By clicking the point under the mouse will be selected. By clicking and dragging the point under the mouse will be selected and moved.

By clicking and dragging all previously selected vector points will be moved.
