I was wondering if there's a way to extract the normal of a specifici face to use it later in something else

In my case what i'm trying to do is a pipe that, in its start point, goes perpendicular to a specific face of my model. So it would be useful to use the normal of the model to start a spline.

heres a pic: enter image description here

Thank you!

  • $\begingroup$ Would this pipe be another mesh object, or part of the same mesh? Because there's object snapping with alignment supports (aligns Z to normal). $\endgroup$

You can also select the face, then "view->align view to selected->front" (shift Numpad 1) and then change the 3d manipulator to "view" (instead of "global" or "local"). Then you can extrude a vertex along the normal by pressing "E YY" or "E XX" or use the manipulator to move along the aligned view axis.

You can use the snapping tools to snap an object to the face of another object, the optional align rotation can also be beneficial.

For even more control you can use the face to define your own custom transformations so you can move and rotate in alignment with the face.
