Summary

Returns Net objects where the total length of arcs and tracks in those nets complies with the Query.

The length of each track is the (Pythagorean) distance between its end points, and is equal to SQRT(SQR(X1 - X2) + SQR(Y1 - Y2)), where X1,Y1 are the coordinates of one end of the track, and X2,Y2 are the coordinates of its other end. The length of each arc is the product of its Radius and the difference between its End Angle and Start Angle, when that difference is measured in units of radians. (180 degrees = pi radians.)

Syntax

NetLength : Number

The entered length is always in units of mils, irrespective of the measurement unit chosen for the board. (1 mil = 0.001 inch).

Example Usage

NetLength = 30000
Returns all Net objects where the total length of arcs and tracks in those nets is equal to 30000mil.

NetLength >= 15000
Returns all Net objects where the total length of arcs and tracks in those nets is greater than or equal to 15000mil.

NetLength <> 5500
Returns all Net objects where the total length of arcs and tracks in those nets is not equal to 5500mil.

Tips

  1. The associated child objects of the complying Net objects are also returned.
