Geometry / Bevel Object
Bevel Object
The Bevel Object controls the cross section of the extruded curve. The Bevel Object can only be another curve
both 2D or 3D, and opened or closed. Editing the handles and control points of the Bevel Object will cause the
original Object to change shape.

Geometry / Bevel Factor
Bevel Factor
Mapping
Allows to control the relation between bevel factors (number between 0 and 1) and the rendered start and end
point of a beveled spline. Map the bevel factor:
Resolution
To the number of subdivisions of a spline (U resolution).
Segments
To the length of its segments. Mapping to segments treats the subdivisions in each segment of a curve as if they
would have all the same length.
Spline
The length of a spline.
Start, End
These options determine where to start/end the Bevel operation on the curve. This allows to make a bevelled
curve which is not fully covered with a bevel.
Increasing the Start Bevel Factor to 0.5 will start beveling the curve 50% of the distance from the start of the curve
(in effect shortening the curve). Decreasing the End Bevel Factor by 0.25 will start beveling the curve 25% of the
distance from the end of the curve (again, shortening the curve).

Geometry / Taper
Taper Object
The taper curve is evaluated along the local X axis, using the local Y axis for width control. Note also that: Tapering a curve causes it
to get thinner towards one end. You can also alter the proportions of the Taper throughout the tapered object by
moving/scaling/rotating the control points of the Taper Object. The Taper Object can only be another curve. Editing the handles and
control points of the Taper Object will cause the original Object to change shape.
Map Taper
For curves using a Taper Object and with modifications to the Start/End Bevel Factor the Map Taper option will apply the taper to the
beveled part of the curve (not the whole curve).
Details
•It must be an open curve.
•The taper is applied independently to all curves of the extruded object.
•Only the first curve in a Taper Object is evaluated, even if you have several separated segments.
•The scaling starts at the first control point on the left and moves along the curve to the last control point on the right.
•Negative scaling, (negative local Y on the taper curve) is possible as well. However, rendering artifacts may appear.
•Might need to increase the curve resolution to see more detail of the taper.
•With closed curves, the taper curve in Taper Object acts along the whole curve (perimeter of the object), not just the length of the
object, and varies the extrusion depth. In these cases, you want the relative height of the Taper Object Taper curve at both ends to be
the same, so that the cyclic point (the place where the endpoint of the curve connects to the beginning) is a smooth transition.
