Well, since there appears to be a mis-match between some timings here and the fact(s) that wine glasses still seem to be objects of desire / interest (and theres not one in sight on the (2D to 3D) aards page) I thought a slightly extended tut strip might be in order.

Having this info here also means there'll also be somewhere (else) to 'point to' - on odf, - should this topic re-surface :-)



1. Using the following method, need to create a drawing canvas for the profile to be rotated in the desired plane. For this, Ive created a cube and extracted one of the vertical faces.
2. Select all 4 edges just press E if still got the face selected. (Ive also got rid of the orig. cube for clarity reasons)
3. Introduce some extra verts using Edge | Cut (4 here) sos youve got something to draw with.
4. View Z, ortho thiss important, otherwise (manipulated) verts wont lie on the same plane, if doing the following ops in persp. view youll introduce unwanted movement off the original plane. Use whatever (appropriate) tool you prefer, to start moving verts around. I used Tweak mode.
5. Situation after tweaking a few more verts.
6.Even more been moved, but the bottom 3 really need to be moved (Y) to get a better envelope for a wine glass. Select em and Move > Y.
7. After the move.
8.Not enough verts in this (selected) edge to adequately define the required shape of the stem / base so Ill add some more.
9. This shows the situation after using Edge | Cut > 7 and moving one of the base verts. Note that I used Vert | Move > x for this, rather than Tweak, cos I didnt want to alter anything else just move it out a bit, to a more suitable place for the base rim.
10. Situation after messing around with the stem. Shape / profile is essentially finished now, but need to remove the 3 selected verts which are on the rotate axis. (looking at the pics I shouldve also removed the extra one on the base but I missed it)


Profile now finished, now time to create the object.




11. Select the face on one side.
12. Apply Face | Lift > LMB and select the appropriate edge.
13. Drag to necessary angle to create a wedge I dragged (and constrained) to 22.5 deg as wanted a std. 16 section object. If you want some weird No. of sections or youre crap at maths, then use Tab input and enter 360/N where N is obviously the No of sections needed.
14. Now basically just a case of mirroring this wedge to get the object. I have all VM options on Hkeys (F5>8), so with face selected I use VM create, VM freeze 2 keystrokes. Now got 45 deg
15. Repeat for 90 deg
16. Repeat for 180 deg. But gotta get rid of the selected edge before final mirror op, else therell be 2 mirror faces instead of one.
17. Select this (now) single, final mirror face and mirror.
18. Final object.
19. Another I made without doing screen grabs etc.

Comments.
The first object, shown in 1 > 18 took about 15 mins to make. However, this included all the screen grabs (34), zooming in /out cos easier to work on a larger view etc but I needed smaller views for the grabs etc. Deciding what bit to grab and how.

So, bearing in mind the time aspect of this exercise I made another, from scratch (19) without any other messing around. From creating the cube to finishing, this took just under 4mins (3.55) of which 3m14s was creating the profile steps 1 > 10, in essence.
The wings object creation time was, therefore about half a min.

Ive no idea how long the first (profile creation) time would take in an app with proper drawing facilities and how much tidy-up time would be needed, because the curves / nurbs > polys conversion etc needed adjustment but its there as a time to be considered.

Theres other factors of course ie whether youre creating a profile to a ref drawing (as could well be the case, using this method)

The above just shows the basics, of course objects with odd Nos of segments, objects with thro holes etc still no problem imo :)

Note that you can select both sides in (11) and lift 2 'wedges' simultaneously ... and that when doing the mirror ops, can also select both end faces and use Mirror > LMB. What's used is up to you, and the No of sections needed.

eg for a 12 section object:
Lift > 30 both sides then mirror both sides produces a semicircular object in 2 steps :)

There's obviously other ways of making this object - but they've not been mentioned, because we're discussing 'lathing' ... and the perceived difficulty of doing this in wings :)

It should also be obvious (I'd have thought - but what do I know) ... that this method of 'drawing' - in wings is also suited (imo) for any other similar requirements ... like a 'custom' cross-section which would then eventually be extruded to form something like a steel joist (for example).

Use other (quicker / simpler) methods when profile precision / exactitudity of shape isn't important :)

Simple:
Make yourself indispensible
Send rest of staff bogus 'pink slips' (or whatever) - telling 'em to stay at home
Suck upto boss even more / big time (could be good if appropriate gender?)
Marry boss's offspring

etc etc

But ... in the meantime, all have got to offer is some boring old junk about solids of revolution ... (sounds like the action of a certain waste product being flushed away ... ?)

mw - as I indicated in the post, it wasn't done 'just' for this thread - this topic has cropped up before (not just from g, but others too) and will, no doubt do so again.

Whenever this happens - or it's suitable for something else, then all someone has to do is reference that person back here (if they feel that above is suitable)

Also - having done it, it can easily be added (if /when so inclined) to relevant page at aards.

I certainly wouldn't have bothered for just a single unique response (unless partic of interest to me).

Anyway - once it's done - it's done - that's it :)
