    diffrent thickness assign on mid surfaces

    i don't know wht buy it doesn't work. this was my procedure: 1)i created two new components 2) i created two new properties but in property card i don't know how select the right surface (or better the elements in the surface that need to have 2.5 or 3mm thickness) so when with f10 i check if i assigned the right thickness it doesn't appear
  11. I have problem with thickness assign, i have only one mid- surface that comes from an assembly and i wanna assign different thicknesses to componets of this surfaces. is there a way to do it ? i created to different properties on my model folder.
