addMiteredPipes Method

Add quad facets along a mitered pipe that follows a centerline curve.

  • At the end of each pipe segment, the pipe is mitered by the plane that bisects the angle between successive centerline segments.
  • Circular or elliptical pipe cross sections can be specified by supplying either a radius, a pair of semi-axis lengths, or an Arc3d:
    • For semi-axis length input, x and y correspond to ellipse local axes perpendicular to each other and to the start tangent.
    • For Arc3d input, the center is translated to the centerline start point. For best results, ensure this arc is perpendicular to the centerline start tangent.
  • This function internally calls createMiteredSweepSections, passing in the startTangent option to preserve the rotation of Arc3d-type sectionData.

addMiteredPipes(centerline: IndexedXYZCollection | Point3d[] | CurvePrimitive, sectionData: number | Readonly<WritableXAndY> | Arc3d, numFacetAround: number12, capped: booleanfalse): void

Parameter Type Description
centerline IndexedXYZCollection | Point3d[] | CurvePrimitive centerline of pipe. If curved, it will be stroked using the builder's StrokeOptions, otherwise
for best results, ensure no successive duplicate points with e.g., createCompressed.
sectionData number | Readonly<WritableXAndY> | Arc3d circle radius, ellipse semi-axis lengths, or Arc3d.
numFacetAround number how many equal parameter-space chords around each section.
capped boolean if true, add a cap at each end of the pipe; defaults to false.

Returns - void
