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.
