The Pen tool creates Bézier curves and the Line tool allows easy creation of straight line segments. All of these tools can also be used to manipulate existing curves. Arc, Spiral, and Triangle tools create curves; B-Spline tool creates B-Spline curves; Context-sensitive Node tool provides control over post-editing objects and nodes.
The grease pencil, a wax writing tool also known as a wax pencil, china marker, or chinagraph pencil (especially in the United Kingdom), is a writing implement made of hardened colored wax and is useful for marking on hard, glossy non-porous surfaces.
The Geometry Nodes utility also has the capability of creating primitive meshes. [36] In Blender 3.0, support for creating and modifying curves objects was added to Geometry Nodes; [37] in the same release, the Geometry Nodes workflow was completely redesigned with fields, in order to make the system more intuitive and work like shader nodes ...
A sketch colored digitally with use of several different blend modes in order to preserve the pencil lines and paper texture below the color layers. Blend modes (alternatively blending modes [ 1 ] or mixing modes [ 2 ] ) in digital image editing and computer graphics are used to determine how two layers are blended with each other.

Pencils are commonly used at polling stations instead of pens. This is because ink might run on to different sections of the ballot and obscure the voter’s choice. The Facts.
To emphasize the two-dimensional nature of such a pencil, it is sometimes referred to as a flat pencil. [2] Any geometric object can be used in a pencil. The common ones are lines, planes, circles, conics, spheres, and general curves. Even points can be used. A pencil of points is the set of all points on a given line. [1]
Every elliptic curve is birationally equivalent to a curve of the Hesse pencil; this is the Hessian form of an elliptic curve. However, the parameters ( λ , μ {\displaystyle \lambda ,\mu } ) of the Hessian form may belong to an extension field of the field of definition of the original curve.
