Data types

String

A String literal is a sequence of Unicode characters enclosed within ASCII double-quote characters. A string literal is of the String type, and contains zero or more Unicode characters.

Insert a new line into a string

There are two ways to insert a new line into a string: the newline() function, and directly entering the newline in the string.

‘Insert a new line using newline() function

"Load = " & load1 & "kg." & newline() & "Load is out of range."

‘Insert a new line directly

"Load = " & load2 & "kg.

Load is out of range.")

The first example is the preferred style.

Number

A Number literal is an integer literal followed by a decimal point. The optional decimal point is represented by the ASCII period character. A Number literal is of type Number.

200.0

0.02

Boolean

Boolean literals True and False map to the true and false state, respectively.

Point

A Point is a representation of a location in space. It contains X, Y, and Z coordinates.

List

A List is a collection of elements of any data type. List elements can be of any valid UnitCAD data type, including other lists. Each member of a list can be of a different data type. Empty lists are allowed.

The following example shows a list that contains five elements of type Number:

List (17, 5, 64, 2, 88)

A list is persisted as a JSON string and contains value and datatype information is required. In formulas, typically the list function is used to instantiate the list.

The following example shows a list whose elements are of various data types. This list contains both literals and other list objects.

List (12, 32.4, "TEST", List ("Item No.", 10272004), List ("Description", "Sprocket"),0)

Vector

A Vector represents a direction and a magnitude. It has X, Y, Z components and optionally a W component for Homogeneous Coordinates.

Plane

A Plane represents a plane in 3d Space and specified by a vector and distance from origin.
