About Connecting Entry Ports or Unconnected Segments
You can connect disconnected segments of the same pipeline or entry ports using the Connect dialog box (click 
Connect). The system does not place a restriction on the orientation of the segments; it connects them even if they are not coplanar or parallel.
Connect). The system does not place a restriction on the orientation of the segments; it connects them even if they are not coplanar or parallel.The default connect uses the minimum number of bends, but you can edit the connect feature to achieve the desired result. A connect feature has 5 dimensions, but only two dimensions can be modified at a time. The remaining dimensions update to maintain the connect. The angles specified must meet the clocking angle criteria for the pipe.
You can create four possible types of straight segments:
• Collinear Segments—System extends the selected segments until they meet, forming a single segment. You can not modify this type of connection and the system does not create a dimension.
• Coplanar Parallel Segments—System extends the two segments and adds an intermediate segment. You can modify the extension endpoints and the angles of the corners. If the current corner type is Bend, the system automatically adds bends. You can control the extension distances at both ends, or the extension distance and angle at one end.
• Nonplanar Segments—System extends two segments and adds an intermediate segment. You can modify the extension endpoints and the angles of the corners as for coplanar parallel segments.
• Coplanar Nonparallel Segments—System extends each segment until they intersect, creating a single corner. You can move the new endpoints of the connected segments to create an intermediate segment.
