Measures surface area: the outer surface of a Solid, the flat region of a profile, or the triangles of a mesh. A Solid's surface is measured to Relative error by cubes cut finer where the surface needs it, as Mass Properties measures; refused by name when its budget ends before that error is reached.
What to measure: a Solid's surface, the flat region a profile encloses, or a mesh's triangles.
How close the result must be, as a fraction of it (0.01 = 1 %; over a surface, of the integrand's size summed over it). The Solid is measured more finely where its surface needs it until the estimated error is this small, within a budget of 40 million field samples.
Values the block gives besides its output. The editor lists them under Properties, and an input can read one by reference.
The value rounded up to a whole number.
The value rounded down to a whole number.
The value with its sign flipped.
The value rounded to the closest whole number.
The value as a field with the same value everywhere.
This value in a Number List of one.
The number itself (kept for documents that read a whole number as a real one).
The number written out as text.
