1.1.9 Line

There are three objects we can use to define 3D representations:

Surface (for polygons) / Circle (special Surface object)
Volume
Line

Each Line object have to include:

first Point object
second Point object
at least one Section/Shape/Surface object

Given two points and a cross section, OpenBrIM can render the line with the specified section profile specified.

More than two points can be specified to define polylines. Also, more than one Section object may be contained in Line objects if more than two Point objects are defined in the line.

Example 3

A Section object can consist of several shape profiles.

<O T="Section">

<O T="Shape">

<O T="Point" X="-width/2" Y="-depth/2" />

<O T="Point" X="-width/2" Y="depth/2" />

<O T="Point" X="width/2" Y="depth/2" />

<O T="Point" X="width/2" Y="-depth/2" />

</O>

<O T="Shape">

<O T="Point" X="-width/4+dx" Y="-depth" />

<O T="Point" X="-width/4+dx" Y="depth" />

<O T="Point" X="width*2+dx" Y="depth" />

</O>
