Hi group,
does anyone know, how to model a spiral groove on a cone? Well, that alone is easy enough, but I want that groove to end in the middle and leave a shape as you would see, if you have a endmill make that groove with ramping out at the end of it. If I use a rectangle (2D projection of the tool), the end is wrong (as is the exact shape of the groove itself). All I can think of is to create multiple points on the trajectory for the groove and cut out holes perpendicular to the cone down to those points. Then I wold create surfaces to connect the sides and the (somewhat) round bottom of those holes to complete the cut. This approach seems to be quite complex and only would give me an approximation.
Any better ideas on how to create a true 3D-cut?
