I've been trying to flatten a set of points, which form a curve in 3D, to a plane, preferably Z = 0.

Here is the screen shot my view: enter image description here

There are 3 kinds of objects in here:

  1. Set of meshes {O3M6.L1.000 - O3M6.L1.013}
  2. Curve drawn (using BTrace -> Objects Connect) connecting the centers of each mesh iteratively. You can find the implementation from the question asked in here.
  3. The minimum bounding box drawn using the Minimum Bounding Box add-on.

What I want is to align these centers vertically. So, if there is any way I could form a 2D plane approximately (with least away from the centers) passing through the centers, please feel free to answer.

I came across this idea, which may 'sound' easy:

  1. Considering the rotations (X, Y, Z) of the cube, in the Transform window, mentioned in the above image, we can rotate the Box parallel to the plane Z = 0.
  2. Note that these rotations could be applied to the Set of mesh we have as a group. Thus, the set of these meshes would be somewhat approximately parallel to Z = 0.

I don't know how to apply rotation parameters of one object to another. Any help is deeply appreciated. Thanks in advance.

  • If you calculate the average z value of all spline points and assign it back to each point, will that be reasonable solution? – TLousky Apr 04 '19 at 09:24
  • I don't think so. Rotation implies change in orientation of objects. Computing mean values will just change the vertical (Z-axis) position. Though after we perform rotation, we can compute average Z-value (say Z), and then translate each object towards Z=0 plane with Z displacement. – Rahul Nalawade Apr 04 '19 at 17:19
