Box

class compas.geometry.Box

Bases: Shape

A box is defined by a frame and its dimensions along the frame’s x-, y- and z-axes.

The center of the box is positioned at the origin of the coordinate system defined by the frame. The box is axis-aligned to the frame.

A box is a three-dimensional geometric shape with 8 vertices, 12 edges and 6 faces. The edges of a box meet at its vertices at 90 degree angles. The faces of a box are planar. Faces which do not share an edge are parallel.

Parameters:

xsizefloat

The size of the box in the box frame’s x direction.

ysizefloat, optional

The size of the box in the box frame’s y direction. Defaults to the value of xsize.

zsizefloat, optional

The size of the box in the box frame’s z direction. Defaults to the value of xsize.

framecompas.geometry.Frame, optional

The frame of the box. Defaults to Frame.worldXY().

namestr, optional

The name of the shape.
