Projecting surfaces to other surfaces

[Joe_Banger]

Hi My draftsman in his wisdom gave me a mid plane surface model for analysis. It was made in ACAD, and I imported it as a 3D sketch to patch into surfaces. However, the surfaces do not intersect (there are 1/2 " gaps through the surfaces), I need each surface to terminate onto its mating surface. I wish to quickly project them into their mating surface, not make millions of 2D sketches and patch then stitch them. Is this possible?

without an image or a file I'm not 100% sure what you're after.  But, if you just need the existing surfaces to "grow" a little to let them intersect then you could try the "extend" command (tucked away in the Surface drop-down) or the Patch command to fill any voids?

YES, this is it! Thank you, yes my example was quite insufficient, English is my 2nd language and I struggle to make myself clear without tuition. The thing that 'got' me was the fact that extend was hidden and in a drop down command menu.
