| Vectorisation
is called for when a scalable template for a toolpath or model is to be
derived from an image or bitmap source. Such vector lines can
be carved or engraved immediately after extraction, providing the
vector is of adequate quality. This chapter again begins with discussion of 'Fundamentals' important to generating vectors optimised for CNC usage. Tasks concentrate on the use of HyCAD and WinTopo to create high-quality vectors from a range of source material. There is some discussion of Inkscape. Vectorisation can be an end in itself or merely the first step in a more involved process. These skills are consequently of use to a large cross-section of CNC users. |

| Task
01: Output
from Task 01 in Chapter 02 is used to explore vectorisation with HyCAD.
Pro's and Con's are considered. Function of features such as
'Join' and 'Scale' are discussed.

| Task
02: Vectorisation
to generate vectors suitable for use in 'Intaglio' or 'V-Carving'
toolpaths. WinTopo is used for this task. HyCAD can perform this work
but there are several advantages to use of 'WinTopo. 'Pros and Cons are
considered
Images created in Task 11 from Chapter 02 are used in this example. |

03: Vectorisation
using InkScape. Means to arrive at accurately scaled output
is covered as well as Pros and Cons of this method of vectorisation. Images
created in Task 11 from Chapter 02 are used in this example.
InkScape's real strengths are as a design application. It generates the content shown on the lower-right from the content shown on the upper-left in a matter of seconds. Vector export tools can then save this as .DXF suitable for CNC uses. |

| Task
04: This
'Task' is really more about avoidance of work with respect to use of
'graphical' fonts.
Many CNC users generate vectors based on graphical' fonts. gmax users have no need to do this. gmax employs any 'true-type' font directly as a vector. They can be applied to CNC use without need of vectorisation. |
