OK I think I have the hang of the Part Sweep tool
Attached is the latest version lure. Its a lot closer to what my friend wants (ultimately he wants a few sizes and shapes etc). A lot of the filleted bits in the first version where not strictly necessary. I just didn't know how to do it another way.
One new problem though. There was no suitable face for the eye holes. Had to sketch them to a different face and they come out at the wrong angle. The pocket should be perpendicular to the taper.
The attached file has a shallow pocket for the eyes so its more visible. The plan is to glue googly eyes in there. The angle may or may not be a problem. If I did need a flat face to get a more perpendicular hole. I'm thinking I could do a 2 stage part sweep, with an extra square halfway down the part and thus get a suitable face for sketching on the tapered bit?
One other thing you guys may be able to help with. The nose of the lure is supposed to spray water as its reeled in. The Chamfer I put on the latest version is a bit of a kludge. I would prefer to have a convex curve here. Thinking maybe use a conic sketch and rotate/groove the nose out? If that’s a good way to do it how would I go about it? I've had limited success with groove. Almost tempted to make a football (Rugby/AFL) shape then boolean cut it out. Or is there a better way? An inverted/internal fillet would be pretty good... But that didn't go well last time I tried...
