[Possible Bug?] Use Relative or Absolute Station in Axis variable (GAXV)?

[netsonic_Sofistik]

I have two models below:

1. The axis is a 10m strsight line, the height of cross section (TVAR variable H) is 500mm at S=0m and S=10m, while it’s 1500mm at S=5m.

As for straight line axis, I have to use RELATIVE station (S) in GAXV, to get the correct result.

GAXV	AI0	NAME	H	S	0	V	500
GAXV	AI0	NAME	H	S	0.5	V	1500
GAXV	AI0	NAME	H	S	1	V	500

S=0.5 means S=5m, S=1 means S=10m.

If I use ABSOLUTE station (S) in GAXV,

GAXV	AI0	NAME	H	S	0	V	500
GAXV	AI0	NAME	H	S	5	V	1500
GAXV	AI0	NAME	H	S	10	V	500

I got incorrect result

2. The axis is an arc with 5m radius, the height of cross section (TVAR variable H) is 500mm at S=0m and S=5 * Pi/2 (at end), while it’s 1500mm at S=5 * Pi/4 (at middle).
   Aqua is the same as case 1

As for curve axis, I have to use ABSOLUTE station (S) in GAXV, to get the correct result.

GAXV	AI0	NAME	H	S	0	V	500
GAXV	AI0	NAME	H	S	3.926990817	V	1500
GAXV	AI0	NAME	H	S	7.853981634	V	500

3.926990817=5 * Pi/4
7.853981634=5 * Pi/2

If I use RELATIVE station (S) in GAXV,

GAXV	AI0	NAME	H	S	0	V	500
GAXV	AI0	NAME	H	S	0.5	V	1500
GAXV	AI0	NAME	H	S	1	V	500

I got incorrect result

You forgot the hashtag:

Thanks. I add more contents in my post.
