Computing peripheral points of spool components from piping component data

A computer program product comprising at least one tangible non-transitory computer readable medium having embodied therein computer program instructions for computing peripheral points of pipe spool components, which, when executed by at least one processor, cause the at least one processor to perform computer processes comprising:

• extracting 3D end point coordinates and leg direction of the pipeline component from component attributes in a piping isometrics model or PCF data;
• deriving two vectors perpendicular to the component's leg direction;
• computing coordinates of an outer diameter of the piping component perpendicular to the leg direction using center key points and the perpendicular vectors;
• projecting the coordinates onto vertices of a minimum rectangle that encompasses the piping component;
• computing minimum and maximum coordinates in X, Y, and Z directions from the computed coordinates for the plurality of pipeline components;
• and
• computing a minimum bounding box for the pipe spool based on the minimum and maximum coordinates in the X, Y, and Z directions.
