Mesh Rotation roundoff error
I have a mesh that has nodes on the Z=0 plane, The nodes are at z=0.0 exactly. I rotate the mesh about the X axis 90 degrees. The nodes that were on the Z plane (z=0.0) are now around -1.0e-14 on the Y plane. The solver I am using needs the nodes to be on Y=0.0.
I used Tools>Rotate Nodes: Selected all | x-axis b X=0.0 Y=0.0 Z=0.0 | angle=90.000 | rotate+
1. How can I rotate the mesh and get the Y plane nodes to land on Y=0.0?
2. If that can not be done How can I move the 20,000 nodes at Y=-1.0e-14 to the Y=0.0 plane?

This should do it:
From the panels (show panels if you don't have them)
Tool --> Project --> to plane --> (change selection to nodes, and pick your nodes, e.g. by face, or on plane) --> to plane 'Y axis', along vector 'Y axis' (set base node coords to 0,0,0)
Alternatively, you could try the aerospace precision tool, ctrl + F, search for precision, pick the nodes you want to change, and set precision, in your case, setting it to 12 or even 13 would remove the inaccuracy
