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.

Syntax:

...
<O T="Line">
...
...
</O>

Example:

<O N="LineObject1" T="Project" Category="3D Geometric Objects">
    <!-- created by ParamML Examples on 31.01.2023 -->
    <P N="height" V="40" Role="Input" />
    <P N="width" V="2" Role="Input" />
    <P N="depth" V="4" Role="Input" />
    <O N="Column3D" T="Line">
        <O T="Point" X="0" Y="0" Z="0" />
        <O T="Point" X="0" Y="0" Z="height" />
        <O N="Section" 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>
    </O>
</O>

The Line object is used in conjunction with the Section and Shape objects.
