Hi,
I'm building on Ansys the model of a bridge, which vertical curvature radius is big. I want to draw curved lines with the LARC function, but ansys draws a complete circle and gives the warning message:
"the two keypoints are coincident with respect with respect to the minimum angle they create at the center of arc. A complete circle will be created."

That's the code I use as example:
FINISH
/CLEAR,all
FINISH
/PREP7
r1_1 = 2427526.79 !mm
K,1,0,0,0
K,2,10000,0,0
K,3,5000,-2000,0
LARC,2,1,3,r1_1

Have someone ever had this problem and found a solution?
Thanks.
