Blender Tutorial Making a Model of a Goblet/Wine Glass Using the Spin Tool (Lathe Operation)


https://i.ytimg.com/vi/YRgcXnd1Wl4/hqdefault.jpg



This tutorial shows how to make a 3D mesh model of a goblet using the Spin tool, a lathe operation similar to a real world lathe tool.

Key points
How to start a mesh model from scratch by deleting all the vertices of the default cube.
How to add, move and delete vertices to make a profile of a goblet.
How to spin the profile about an axis to create a 3D model (removing doubles).
How to close holes in the model.
How to apply the Subdivision Surface modifier.
How to use Smooth shading and correcting any banding caused but not correctly calculating face normals.

In detail –
Go into edit mode and delete all the vertices of a cube.
Add new vertices by holding down Ctrl and pressing the left mouse button.
In Front view draw the profile of a goblet by adding vertices.
Edit the profile by moving, deleting (merging) and adding vertices (Subdivide).
Go into top view and make sure the 3D insertion cursor is center (Mesh menu – Snap, Cursor to Center).
Click spin, change the Degrees to 360, change the number of steps to 24.
The profile is duplicated 24 times the last time on top of the first, select all and remove doubles.
Filling holes by selecting a ring of edges, extruding a new ring and scaling it with value of zero (remove doubles)
Apply the Subdivision Surface modifier setting the level of subdivision to two.
Apply Smooth shading to remove any banding go into Edit mode and select all, in the Mesh menu select Normals and Recalculate Outside.

  1. This seems rather clunky though, there's no need to have/edit a cube, also closing the model in that manner appears to leave a multitude of superfluous facets and vertices within the stem of the goblet.

  2. Thanks for the tip about control-clicking to add the points. I was fighting with the unbelievably rubbish Bezier curve tool trying to get it to behave, then not being able to spin it at all. Bezier curves in Blender are HOPELESS!

  3. Hi Ian…Very clear imparting/tutoring. A problem I'm newly encountering, having used the spin tool quite a few times over recent weeks, is that the parameters of the spin operation usually appear (on L clicking "SPIN") but no longer appear and I'm stuck with a default 90 deg./9 segment spun object and can't alter those parameters. Any ideas on how to retrieve these? Spin becomes useless with this restriction as I was looking fwd to using it to recreate cast iron mouldings and multi arc geometry
