Align pivot rotation to line [solved]

[evanrudefx]

Hey,

I have a line that I would like to transform in the direction of the curve. How can I rotate the pivot rotation to match the line? I am trying to match the Z axis to the line by rotation the pivot rotation y.

Thanks

not sure if i understood the question right but to rotate the pivot you can press the insert key to change the rotation to the desired axis

The question was how to align it perfectly.

You can just grab both end points and subtract them. This will give you an offset vector to slide the line along. Not really an answer for the pivot, but covers your first sentence request.

thanks for the ideas. I actually have the transform on another piece of geo that I want to move in the direction of this line.

I think this may do what you need:

1. Template the reference geometry (in your case, the line)
2. Select the Transform SOP and display the handle
3. Enter Pivot Mode [Ins]
4. Start Orientation Picking [;]
5. RMB on the Viewport > "Use Extended Mode"
6. Determine which two points (P, Q) on the reference geo will define the Z axis of the pivot (the pivot will be placed on P)
7. Shift-LMB on the Q point, then LMB on the P point
8. Exit Pivot Mode [Ins]

cheers! I didnt even know you could do this!!! thanks

I figured out a solution that works really well. On my curve/ line use poly frame. For tangent name use N.  I create a transform axis node on the object I want to transform. Just copy the Normal values to the Direction of the transform axis. Then you can animate the translate value!
