I dont remember seeing this type of tip in the sketchup basic tutorials…and I think it should have a way to move a line or face until it matches a reference point ( as I try to show in the video )
I need this bricks texture to be at the same height of the other in the perpendicular wall.
It would be so nice if we could have Reference Point like the Snap cursor does in AutoCad. Look how many options they have there, it makes our work so much easier
If you use the dropper(B+Alt) and immediately paint the other face, the textures will match, you can also right click on any face, on the contextual menu go to texture/position and move it, scale it or deform it until it matches the other texture, but this method isn’t so accurate, also sketchup snapping in my opinion is better than most of the softwares, the only feature I wish it had is the ability to turn off/on snapping options like on Autocad, but it has a almost the same snapping options than Autocad, endpoints, middle points, intersection, parallel, perpendicular, tangent and center.
its not about matching textures… I dont think you understand…I just want that face I pushing up to be the same heiight of the bricks (face) in the perpendicular wall…but it wont show me a reference point so I can do it…like when we push pull
Select the line to move it, get it to inference the blue axis, hold shift so it goes bold, then pick a point on the other wall you want to snap to.
Select the line, select the move tool, click on the line, hit the 
key, place the cursor on an end point on the other line and click once you get the snap.
Move the blue edge (see image below) up constraining to blue.
While doing so don’t inference to the perpendicular edge on the other wall but to its endpoints or on its midpoint, so three reference point options.
thank you but I cant find those reference points…look
Can you share that file? Not a video, nor screenshots.
I would like to see that perpendicular “edge” on the other wall.
Does this help?
Using the move tool, while pressing the shift key or pressing the up arrow key to constrain the axis to the z-axis, moving in the z-axis direction will snap to a snap point.
I simply use guidelines to mark the height around the corner. (they don’t mess up the geometry). Dbl click with the tape measure tool on your first line (to establish that height) This extends the line indefinitely with a dashed line.
Using the tape measure tool click on the bottom line of the opposite wall and drag up another guide line. While dragging up the wall with the mouse button still depressed, click on the first guideline or the first line on wall 1 to align the guide you are now dragging on wall 2 with the new guide.
The new guide on wall 2 will align and be on the wall 2 face. Trace the guideline. Voila!
I’d learn about guides. I use them death. Very helpful.
I would still like to note in addition and in principle:
All elements like wall or coatings or claddings should be separated by " GROUPS "!
The more complex the whole construct becomes, the more you will get problems by “GLUING” the different geometries!
Unfortunately, under Sketchup this basic logistic rule is not recognized and followed and creates problems again and again.
Furthermore, I would give all claddings (with foresight) a minimum thickness in addition to the grouped independence (3D), as in reality. This prevents possible interference with rendering programs.
Remember: ! You are modelling geometric bodies in addition. This is not “drawing” my thoughts as on paper … !
Not sustainable problems! But sustainable modelling ! 
Thank you Bentsky But sometimes I need to make it simple for the file to be light
