# Add Connection Point

A connection point is a feature displayed as a directional axis, used to control the start/end point of a pipe and also to manage connections between piping components.

How to use：

  1. Create a new part, complete the sketch, then click on "Path - Connection Point."

  2. Select the geometric elements to define the connection point's position.

  3. If the selected geometric element is a circular edge or a plane, the system defaults the connection point direction to be perpendicular to the plane. You can click the reverse icon to change the orientation. If the selected element is a sketch line/point or a model edge, the connection point direction must be manually defined by selecting a geometric element.

  4. Determine whether the connection point needs to be offset based on your requirements.

  5. Select the piping type, and determine whether to enable the grade rule based on your requirements.

  6. Set the relevant parameters.

Dialog Box Control Instructions：

  • Connection Point Position: Only a single geometric element can be selected. Supported elements for selection: origin, sketch point, endpoint of an edge/sketch line, circular edge, or circular plane as the connection point position.

  • Connection Point Direction: If the selected connection point position does not require a specified direction, the system will automatically fill in the direction. If a direction needs to be defined, the user must manually pick a geometric element to determine the direction.

  • Offset: Controls whether the connection point starts from an offset along the connection point direction from the initial position. By default, this is unchecked.

  • Category: Options include "Piping," "Cable," and "Wire." Parameters differ between the Piping and Cable categories.

  • Grade Rule: Appears only when the category is set to "Piping." Used to record the piping attributes of the part. The system default grade rule is seamless steel pipe. Users can customize the grade rule in the "Path - Grade Rule" section.

  • Outer Diameter / Wall Thickness / Flow Direction: Basic pipe attributes, required fields.
