A quick question, I have this hole to do on SolidWorks, but I'm a little dry on how to do it. It is a milled hole on the base, extended like a groove over 4 mm. (I attached a quick 2D map to this message).
For my part; I will do a material removal from above to the max depth and then I used the chamfer function to finish. Or you can do half of your front view as a sketch and then a second one with the top view make it a swept material removal
