Pipe is the space markup element used to graphically draw pipes in fluid simulation models.
It is the animation shape for a pipe defined logically with Fluid Library block Pipeline. You draw the Pipe according to the pipe topology, and customize its appearance via the pipe's properties (namely, set its color, diameter, and optionally alter Z-coordinates). Pipeline block defines all the logic for the pipe (its capacity, rate, initial amount of liquid inside the pipe, color of batches flowing through the pipe, etc.).Pipe is displayed both in 2D and 3D animation (to see the pipe in 3D, add 3D window in your model). Pipe may have turning points and contain several segments, see the figure below.
At model runtime batches flowing through the pipe will be animated as cylinders moving inside the pipe cylinder. The color of liquid cyinders is not defined in the pipe shape, but it is defined in the Fluid Library flowchart.
The pipe has start point and end point. The liquid will always flow from the pipe's start point to its end point, so the pipe direction is very important. Pipe end points can be put at storage tanks, or left just "hanging".

To draw a pipe
Name – The name of the pipe. The name is used to refer to the pipe from the Pipeline block properties.
Ignore – If selected, the pipe is excluded from the model.
– If selected, the pipe is also visible on the upper level
this agent lives.
Lock – If selected, the pipe is locked. Locked shapes do not react to mouse clicks - it is impossible to select them in the graphical editor until you unlock them.
Visible – Here you specify whether the shape is visible on animation at model runtime, or not. Using the control, choose yes or no.
Color - Here you can set the pipe color.
Diameter - Here you can set the pipe diameter, in pixels.
X – X-coordinate of the pipe's start point.
Y – Y-coordinate of the pipe's start point.
Z – [Enabled if the shape is visible in 3D (advanced property Show in is set to 2D and 3D or 3D only)] Z-coordinate of the pipe's start point.
The table located in the Points properties section enables users to view and adjust coordinates of the pipe turning points. It is the place where you can adjust the Z coordinates for some pipe points.
Here you define
relative coordinates, not the absolute
ones. The first point always has coordinates (0, 0,
that can not be
Other rows of the table define relative coordinates of the successive points. Coordinates of each point are actually offsets of the corresponding point from the start point along X, Y (and optionally Z) axes correspondingly.
Show in - Here you can choose whether you want the pipe to be shown both in 2D and 3D animation, or in 2D only, or in 3D only.
Show name – If selected, the pipe's name is displayed on the graphical diagram.
The pipe has direction. The liquid will always flow from the pipe's start point to its end point. So it is important when you draw your pipe, where you put the pipe's start point. However, you can always change the pipe direction (see below).

You may want to split a pipe into several pipes (for example, to put a valve inside).
