Line String commands

Hello again

This time we need some help concerning "Line String" commands.

On Microstation V8i we had on the Tablet menu (55menu,cm) 4 options of Line String commands as follow:

-Smart Line

-Line String

-Stream Line String

-Curve Line String

On Prostructures (V8menu,cm) we could only find the 2 last command options. Can anyone tell us where is the "Line String" option.

Thank you in advance

Regards
