Line
In OpenBrIM, 3D representations can be defined using the following objects:
Surface
Volume
Line
Each Line object must include:
A first Point object
A 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. For polylines, multiple points can be specified, and a Line object can contain multiple Section objects if multiple points are defined in the line.
To create a line, two "point" objects are required that define the start and end of the line. These points are combined using the "line" object to express the line.

<br><O N="LineObject1" T="Project" Category="3D Geometric Objects"><br> <!-- created by ParamML Examples on 31.01.2023 --><br> <P N="height" V="40" Role="Input" /><br> <P N="width" V="2" Role="Input" /><br> <P N="depth" V="4" Role="Input" /><br> <O N="Column3D" T="Line"><br> <O T="Point" X="0" Y="0" Z="0" /><br> <O T="Point" X="0" Y="0" Z="height" /><br> <O N="Section" T="Section"><br> <O T="Shape"><br> <O T="Point" X="-width/2" Y="-depth/2" /><br> <O T="Point" X="-width/2" Y="depth/2" /><br> <O T="Point" X="width/2" Y="depth/2" /><br> <O T="Point" X="width/2" Y="-depth/2" /><br> </O><br> </O><br> </O><br></O><br>
The Line object is used in conjunction with the Section and Shape objects.
