# Precision object positioning question

Hello, everyone! Quick question to you more experienced modellers.

How might someone position an object on a particular, but odd, angle? For example, if I had two particular vertices in separate objects, and wanted a bridge between them, how might I precisely position an object so that its end-vertices line up with those? For help explaining what I mean, here are some images. Thanks for your help!

Love,
Micah

If all you want is to move it one time then use the Pivot selector to rotate relative to the
3D Cursor.

Hope this helps.

Or some math! :evilgrin: The triangle formed by the cursor and the point on the sphere is 2*2, i.e, isosceles, and since blender’s units are square, the vertex angle is right, so each base angle is 45 degrees (press R then 45), since a triangles angles add up to 180.

I’ll admit to using math too… but exactly how exact do you really need to be?

but there’s really no need. Place the 3D Cursor at the first point in the line (the side of one of the spheres), press Alpha-period (for rotate by cursor), place the mouse pointer above the tube’s pivot point (the big dot in the middle of it), press R to rotate, place the mouse cursor at the last point in the line, click.

Now, snap the cursor to the tube’s pivot point. Place the mouse pointer at the center of either end of the tube, press R to rotate, place the mouse cursor at the last point in the line, click.

If you find that the tube is too close to one sphere or the other: place the 3D cursor
at either end of the line, click the “Move Object Centers Only” button to the right of the Pivot drop-down box on the menu bar, and press S to scale the object’s position as desired.

Hope this helps.
