### GEOMETRY_PIPE

###### Geometries
*GEOMETRY_PIPE
"Optional title"
gid, csysid
$x_1$, $y_1$, $z_1$, $x_2$, $y_2$, $z_2$, $R_1$, $R_2$

#### Parameter definition

VariableDescription
gid Geometry identification number
csysid Local coordinate system ID
default: global coordinate system is used
$x_1$, $y_1$, $z_1$ Face center coordinate 1
$x_2$, $y_2$, $z_2$ Face center coordinate 2
$R_1$ First radius at face 1
$R_2$ Second radius at face 2

#### Description

This command is used to define a straight pipe or cylinder in space, with its face center coordinates at ($x_1$, $y_1$, $z_1$) and ($x_2$, $y_2$, $z_2$). Note that the smaller of $R_1$ and $R_2$ is automatically taken as the inner radius.
