Dear all I have a layer shapefile lines with around 30 lines.

I need a buffer of one of these  lines with 2 different values of buffer
distance: 150 m on the left and 30 m on the right.

Which kind of buffer option can I use??

I know only single sided buffers but with this option I need to  repeat the
buffer for every side.



Thanks to all, A.L:
