Circular array

Just doing a board, on it there will be a circular array of 72 parts, is there an easy(!) way of using a spreadsheet or similar to drive the locations X, Y, Theta for each of the parts?

You can make a spreadsheet with 72 rows, and compute the X,Y and rotation of each part using a formula. Select all 72 of the X coordinates, then use the PCB list view, and paste in the 'X' column and it will paste all 72. Repeat for Y and rotation.

You can also make a polar local grid and do the same, this will simplify the formulas somewhat but is otherwise equivalent.

Just make a polar grid.

Brill thanks for both suggestions. Not used polar grids before.

Didn't use polar grids in the end.  Used the "PCB List" feature and inserted data from a spreadsheet - worked perfectly thank you.
