The following requirements apply to **‘flow-through components’** in Smap3D Piping for SOLIDWORKS**®**, i.e. for components which are inserted between pipes and through which some medium should flow.

These are components such as **‘bends’**, **‘tees’**, **‘flanges’**, etc.

Each possible connection on a component needs an **‘INPUT_POINT**‘, an **‘OUTPUT_POINT’** and an** ‘OUTPUT_AXIS’**.

The proper coordinate systems and axes can be created easily using Coordinate System Wizard.

**Example:**

A tee has three ways it can be attached to a pipe. Therefore there are three input and three output points.

Each connection must have an **‘INPUT_POINT’**, an **‘OUTPUT_POINT’** and an **‘OUTPUT_AXIS’**.

This means that a tee prepared for use in Smap3D Piping contains 6 coordinate systems altogether (3x INPUT_POINT and 3x OUTPUT_POINT) and 3 axes (3x Output_AXIS).

**The X-axis of each coordinate system must always point in the direction of the INPUT or OUTPUT.**

Since Plant Design 2016 you can use the Component Wizard for an easy and fast creation of such components:
