For users that need to create 3D sketches but dimension along the X, Y or Z axis, there is an easy trick using smart dimensions. Simply create a point to point smart dimension, then before placing the location, hit the tab button to cycle through the dimension type. The initially placed dimension will be the absolute dimension, followed by the dimension along the X, Y and Z axis respectively See the GIF below.
Hopefully this tip will save you some time dimensioning your 3D sketches instead of creating construction lines to achieve the same goal.
