18.1 Modeling using the Grease Pencil
In the Grease Pencil a Model is created by drawing Strokes in a Canvas. A Canvas has been
described as being a Three Dimensional Container, therefore, Strokes in the Canvas may be
arranged to create a three dimensional shape, which is then converted to a 3D Object.
Besides arranging Strokes into a shape, individual Strokes may be given Geometry. This means
the Stroke is given form which displays the Stroke as a three dimensional Object. This process
may be applied to a single Stroke or multiple Strokes.
Whether arranging Strokes to create an Object or giving a Stroke Geometry, the final result
depends on Drawing and arranging the Stroke or Strokes in 3D Space. Controlling and Placing
Strokes is covered in Chapter 7 but requires further explanation specific to Modeling using the
Grease Pencil.
To begin Modeling using the Grease Pencil a model consisting of a single Stroke will be
demonstrated.
18.2 Modeling a Stroke
The simplest Model that may be created in the Grease Pencil is to generate a model of a
geometric shape from a simple straight Stroke. The Stroke is Drawn in the 2D Viewport Editor in
a Canvas on one of the Layers (see Chapters 1 and 6).

Select Mode – Only Points
you see the Stroke is made
up from a series of Vertices.

Basic Procedure: When creating a Model from a single Stroke or from multiple Strokes, the
Strokes are Drawn, then Converted to Paths. Geometry is created from the Path or applied to
the Path. The Path is finally converted to a Mesh (Mesh Object). All Strokes Drawn on a Layer in
the Canvas are treated as a single Object, therefore, the multiple Strokes create one single
Object. When Converted they create a single Mesh Model.
