This function requires a T=”Section” object as input and calculates the Z-coordinate of centroid of the section.

sectionDepthsectionPerimeter( Section ) → number

This function requires a T=”Section” object as input and calculates the depth total length of the section by finding the difference between the maximum and minimum Z coordinates outer boundary of the points defining the section.

sectionWidthsectionDepth( Section ) → number

This function requires a T=”Section” object as input and calculates width the depth of the section by finding the difference between the maximum and minimum Y Z coordinates of the points defining the section.

sectionPerimetersectionWidth( Section ) → number

This function requires a T=”Section” object as input and calculates the total length of the outer boundary of width of the section by finding the difference between the maximum and minimum Y coordinates of the points defining the section.

sectionExt( Section ) → list of list of number [[minX,minY],[minX,maxY],[maxX,maxY],[maxX,minY]]

This function requires a T=”Section” object as input and returns boundary rectangle coordinates of the section.
