Im a max/maya user and i have been trying to move those points for 2 days now! On each side - the top and on the bottom there are 2 pyramid-formed Boundary Boss/Base extrusions to a 3d plane. Between them there is a point. I cannot move it up into X-Asis! Only to YZ! I would like to have no "gap" between those 2 pyramids - the point between them should be on the same height as the pyramids. Points are marked with arrows. Pyramids with lines. Please, i need help with this asap! If i cant pull it up, how can i REBUILD that face, so that i has the shape i want?

I'm not sure... try moving the vertex point around on that sketch. Perhaps you found a point that makes the surfaces intersect weird. Or adjust the offset of that plane from your prior surface (3mm or 4mm or something).
