Drawing

RealFlow can read splines that have been saved in SVG format (“Scalable Vector Graphics”) - a XML-based file format. Furthermore, splines can also be drawn inside RealFlow directly. SVG splines are exported from popular illustration and image-processing applications. The spline-based tools and nodes are located here:

Spline shelf

When you choose “Spline” from the “Spline” shelf, an empty container is added and the → viewport is set to “Edit” mode. A yellow frame indicates this mode:

• A new control point is created with Ctrl/Cmd + RMB. If you want to add Bezier tangents to the control point do not release the mouse, but drag it to control curvature.
• If you do not drag the mouse after the creation of control point you will get a linear connection between the points. It is not possible to change a control point's type from linear to Bezier or vice versa.
• New points will always be added after the spline's last point.

Remove Points

• Select one more points (Shift-click).
• Press Del.

Add Points

• Press Ctrl/Cmd.
• Move the mouse over the spline where the new points should be inserted – a circle appears.
• Right-click to add the point.
• New points are always added as Bezier points.

Interrupt and Resume Spline Creation

The creation of control points can be interrupted and resumed at any time with a click on
