Draw perpendicular arrows to a surface. These arrows are inside another surface.
Hello! Im an engineering student that likes to do illustrations for my digital notes (I have done a few for notes and presentations). Please, have mercy jaja I am far from the skills I would like to have as a graphic designer.
Please, see the image attached. I need to create a series of arrows that are encapsulated inside the area delimited by the blue line. Also note, that those arrows need to intersect with the black line (another surface inside) at an angle of 90 degrees. I have no clue if there is a special command to condition the arrows to be perpendicular to a surface and if i could condition them a starting and end point that intersects other lines.
Thanks!
