Subject: Re: Sorting Lines by Type (Straight, Arc, etc)
Author: Scott Reiss
Date:

Peter Budgell and John Swanson had good suggestions for finding whether the
line is straight or not. To determine whether a "not-straight" line is an
arc (as opposed to another type of curve) you can use the following;
Characterization of other curve types would be much more difficult. Hope
this helps!

! Perform test to check whether arc is part of circle.
! Based on equations; chord=2*rad*sin(ang/2) and length=rad*ang
! where ang (radians) is solved for in first equation and placed in
! second equation. Use percent difference between chord and equations
! as check where % difference must be less than 0.5%.
archck=100*abs(chord-2*rad*sin(length/(2*rad)))/chord
! If equations are equal it must be an arc so continue.
*if,archck,lt,0.5,then

possible (probably by using APDL)to distinguish between a line that is
straightand one that is an arc?Thanks,Jean-Pierre Dube0Q64 MCAD Tools and
