I have a point on a surface lying at u=0.5 and v=0.5. It is moved to another place in the space with XYZ coordinates that for certain lies on the surface, how do i extract the UV values?
Go to Geometric properties, change the analysis type to static, select the face of interest, then in the analysis point option - click the icon to open the point dialog and change the type to "existing point". Select the point object that is on the surface and you will find the UV values in the results.
If the original point was created as an associative "point on face", you can edit the point feature and it will show the current UV parameters. If you select a new location on the face, the updated UV parameters will display. You can edit the point by selecting a new location on the face or by editing the UV parameters.
