Expression table and radians mode
Expression table and radians mode
(OP)
Hello,
I would like to be able to enter the geometric formula which solves for the length of a side of a polygon.
Side = 2(inscribed radius of the polygon)tan(pi/(number of sides of the polygon)
This formula only works when a calculator is set to radians mode. Is there a way to set the expression table to use radians mode instead of degrees in a geometric formula.
I know that I can just put a measurement of one line segment into the table, but as the polygon changes its number of sides, sometimes the line that was measured gets lost and then I lose the measurement.
This is not just converting the units from degrees to radians using rad(). The units in this formula are length on angular. If one sets a scientific calculator to radians mode the formula works in degrees mode, it does not and provides the same value as the NX expression table.
Thank you,
Andy

A UG tech working with us found it deep in the knowledge fusion help.
Setting the dimensionality to angle does not work because there are no angles in the formula as i noted above. The dimensionality has to be a unit of linear measure inches, centimeters etc. A 54 sided polygon with an inscribed radius of 8.125" would be the inputs.
a=(2*8.125")tan(pi/54) for example
thanks again for the answers though.
