After watching so many tutorials I thought I could quickly pose a short question here. I want to add some topography to an extruded object which I imported from a 2D vector file. The problem is that in ordner to sculpt it I need to add some more polygons on the top face and on the sides. I know this could be done with the knife tool but I'm searching for a way to turn this into a nicely ordered grid. I've tried out the boolean intersect but did not advance this far enough.
How can I add more polygons to the red object? Should I try to combine the top face with the grid on top and intersect the sides with the planes below?
Thanks a lot in advance!
