Mapdl.kmodif(npt='', x='', y='', z='', **kwargs)[source]#

Modifies an existing keypoint.



Modify coordinates of this keypoint. If NPT = ALL, modify coordinates of all selected keypoints [KSEL]. If NPT = P, graphical picking is enabled and all remaining command fields are ignored (valid only in the GUI). A component name may also be substituted for NPT.

x, y, z

Replace the previous coordinate values assigned to this keypoint with these corresponding coordinate values. Values are interpreted according to the active coordinate system (R, θ, Z for cylindrical, R, θ,Φ for spherical). If X = P, graphical picking is used to locate keypoint and Y and Z are ignored. A blank retains the previous value. You cannot specify Y = P.


Lines, areas, and volumes attached to the modified keypoint (if any) must all be selected and will be redefined using the active coordinate system. However, solid modeling in a toroidal coordinate system is not recommended.

Caution:: : Redefined entities may be removed from any defined components and assemblies. Nodes and elements will be automatically cleared from any redefined keypoints, lines, areas, or volumes.

The KMODIF command moves keypoints for geometry modification without validating underlying entities. To merge keypoints and update higher order entities, issue the NUMMRG command instead.
