Create transparent material for Sections and/or Elevations

[alegafs_92]

Hi everyone,

I would need some help in order to make a semi-transparent material for Elevations or Sections.

In the image attached you can see what I want to achieve in 3D View and what I get in Elevation view.

I would like the material transparency in the Elevation to appear the same as in the 3D View.

I hope I have been clear, thanks for help!
