This is a very popular tutorial for beginners. In this detailed tutorial we will learn a technique for creating a realistic wine glass using an Editable Spline and a Lathe Modifier. Enjoy!
Let's get started. First we need to change the Units Setup to Centimeters. We can do this by clicking on Customize on the Top toolbar and select Units Setup from the menu. In the Units Setup Dialog – Display Unit Scale, choose Metric and Centimeters.
In the Perspective viewport let's turn on Edged Faces. We can press F4 on the keyboard or right click on the word Realistic in the left corner of the viewport. This will enable us to see all the subdivisions in our objects.
We are going to create a Plane first as a reference point to draw out the exact size and shape of the glass. So go over to the Create Panel – Geometry and select Plane. Drag out a Plane in the center of Front viewport. Then go to the Modify Panel, in Parameters type in Length 16cm, Width 7cm, and Length and Width Segs 4. Press Z on the keyboard to zoom in.
Let's maximize the Front Viewport to draw out the shape of the glass. All we have to do is press ALT W on the keyboard. Now we can go over to the Create Panel – Shapes – Splines, in Object Type select Line then turn on AutoGrid.
We are going to draw out the outline of half a glass on the Plane then add a Lathe Modifier. We do not need to create a lot of vertices for this shape, but it is important that they are placed in the same position as the image. We will start at the bottom left corner. Click to drop the first vertex (the first vertex is always yellow) then hold the shift key down on the keyboard to draw a straight line and drag the Line to the right and click again in the middle of the Plane. Don't press the Shift key now and draw out the top outline of the base of the the glass. Hold the Shift key down to drag the Line straight up for the stem of the glass, click and drop an other vertex. Carry on drawing the outline, the last vertex must be place precisely above the first vertex. Right click after placing the last vertex to turn off the Line.
Let's go over to the Modify Panel, and choose Segment Sub-Object mode. With the Select and Move tool you can adjust the width of the outline.
Go to the Vertex Sub-Object mode, and select the two vertices at the Top of the glass and zoom in. Scroll down the panel to Geometry, and press the Fillet Tool. Click on a vertex and drag the cursor up. The original vertices will disappear and they will be replace with two new ones and curved segments.
Select the two vertices in the center of the curve,(there should be one on top of the other like in the image) and in the Geometry panel press Weld to weld them together.
Let's go to the inner vertex inside the glass, right click on the vertex and from the Tools 1 menu choose Bezier. Move the Tangents on the vertex slightly until you get a smooth curve.
Now we can select the vertex at the top of the stem and press the Fillet Tool. Click on the vertex and move the cursor to create a curve. Do the same to the vertex at the other end of the stem.
Right click on the vertex on the base of the glass and choose Smooth from the Tools 1 menu, then move the vertex so you get a nice even curve.
We can now go back to the middle vertices on the side of the glass. Select both of the vertices, right click and select Smooth from the Tools 1 menu. Pull the vertices slightly to the side, creating a smooth curve. Then move one of the vertices so they are closer together. Make sure there are no lines over lapping.
Back over to the Modify panel and click on the name Line to turn off the Sub-Object mode. Now from the Modifier List, scroll down under Object-Space Modifiers and select the Lathe modifier.
We will see how the Lathe Modifier rotates around the object. Let's adjust a few of the settings. In Parameters, turn on Weld Core, Segments set to 32, and in Align press Min.
We can delete the Plane now, and let's have a look at the glass. If you're not happy with the result you can easily make some adjustments. Turn on Show End Result On/Off Toggle, then go back into the Line Sub-Object mode - Vertex mode and move the vertices and at the same time you can see how it looks. When you're happy with the result you can right click and in the Transform menu select Convert To Editable Poly.
All you need to do now is add some Glass material.
I hope you have found this tutorial helpful and can apply this technique to future projects. Enjoy!
