CST _ defining curve

Hallo,

i want to define a line in my CST MWS model, for calculating the
integral of E along a line afterwards.

Defining lines is only possible in the xy-area, whats wrong ?

use the 'local coordinates' , a UVW coordinate, and rotate it around one axis. Draw the line in the UV plane.

Or you can use 3D polygon to draw a line .

the other way to define a 3D line is use command 3D polygon

it seems that in the macro there are 2D curve and 3D cureve creation!
