I have a problem and i can't find a solution. I have a face on my object. I want to align a vertice so that vertice is on the same plane of the face. I created a Trasform Orentation on the face so that i have the right axis where to move on the vertice. I also set the 3d cursor but when i want to put z=0 the vertices doesn't align with the face. I know that the problem is the local origin but i can't find any other method. I can move the vertices put all coordinates to 0 and restore x and y but it's a very dirty way. 3D cursor on the face with right alignment

the vertice that i want to align with this face. if i put z=0 doesn't work

  • $\begingroup$ Use snap to face option maybe and grab along the axis you've defined. $\endgroup$

  • $\begingroup$ it's a good option for my purpose but it's not what i would like. I would that the cylinder has vertices on the plane without deform it $\endgroup$ Commented Sep 9, 2020 at 14:09
  • $\begingroup$ Hard to see clearly how things are on the pictures. Could you upload a blend file with the key elements in it? blend-exchange.giantcowfilms.com $\endgroup$

  • $\begingroup$ i added the blend file. There many of theese situation. I'm trying to make a non manifold object for 3dprint. I know that i can do this thing in some more dirty ways but i also want to do a nice job, just for learn. $\endgroup$ Commented Sep 9, 2020 at 16:09

    $\begingroup$ So, the custom orientation should be from the edge/face on the disk part. Then set snap to face and grab the vertex along YY. Keys G to grab the Y and Y to go along the custom edge orientation. $\endgroup$

If you want to snap all the vertices of the rim to the surface at once, you could assign them to a Vertex Group, temporarily P split the hatch off into a separate object, and give it a Shrinkwrap modifier, affecting only the vertex group, targeted on the surface.

enter image description here

If you align the hatch object-axes down the edge of interest,then you can use the modifier to project all the vertices in the desired direction. Apply the modifier, rejoin the objects.
