Reuse Feature with multiple associative csys or a sketch containing points and constrained somehow will give you that functionality.
Or simply a Sketch with points (constrained to x, y, z) and you can simply import the expressions from spreadsheet.
you can use UG_cell_Read in the expressions.
Make for every point a X,Y,Z expression and link the to a cell
after changing the excel use the "update for external Change" to update the part file.
only if it are a lot of points it can take some time
Thank you all for solutions but there are more than a 100 points on the same plane. Is there a faster way to do this? I’ve already tried the approaches commented above
