I had the same problem with the sweep using a rounded curve as the rail. I tried to model an inhalator with some curvy grooves (see attachment) on the outside. I tried the following approaches:
- Use "trim" with an extruded curve to derive the contour of the groove along the object. Then I hoped to do a sweep along this curve with a circle. I wanted to subtract this shape from the object using the "boolean" function. However, the boolean did not work, probably because the contour was not properly closed. On rectangular objects I had the same problems as described in this thread.
- Then I used another approach, namely create a "shell" of the extruded curve (with the required thickness of the groove). Using booleans I cut a hole into this shell. Then I bevelled the inside of this hole, scaled the shell with the bevelled hole at 95% and subtracted this from the original shape.
The big downside of the second method is that the "scale" will not result in an equal depth of the groove along the object. Is there another method to create such a groove?
Yours sincerely,
Ray
(I added some screenshots that illustrate the methods described above. I hope it helps)
