You always need urns. They're great for plant pots, decoration, filling empty spaces, and what's more they are really easy to do. Here's how.
Open up max and maximize the front viewport. Go Create>Shapes>Circle and drag it out on the screen. Right click and choose 'Convert to....Editable Spline'.
Hit '2' on the keyboard to activate segment mode, then select half the circle and delete it.
Now right click again and choose 'Refine'. This adds vertices wherever you want. You can see here that i have added three new verts.
Right click again to deactivate the Refine tool, then area select the vertices and start moving them to where you want. You can also delete the segment at the top as this is going to be the opening of the urn.
What we do now is to turn the line into a closed shape. Hit '3' on the keyboard to activate Spline mode and click the line to select it (it should turn red). Scroll down the right hand panel until you see 'Outline'. Click the button then drag the line with the mouse. You can see the results below. I have made this line quite thick just so you can see it more clearly, but it would depend on what kind of urn you wanted to do.
Click the little black arrow to the right of the modifier list to bring down all the possible modifiers that we can add to the object. In this instance we want the Lathe modifier, so select that. Here I have changed the degrees to 180 or half, as I want to modify the urn a bit later on and then copy the other half so i don't have to waste so much time. The default number of segments is 16, but if you want the urn to be close to the camera you will need to increase that number or the results will look very choppy. Play around with the Direction and Align values too, just to see what happens.
Very important! Save your urn now. This can then be used as the basis for an almost infinite number of variations. All you need to do is click on the 'Editable Spline' in the stack and move the vertices. Once you are absolutely sure you have the shape you want, right click the object to select 'Convert to...Editable Poly. After you have done this you won't be able to modify the lathe or the spline, so be sure to save your work! Hit '4' on the keyboard to enter polygon mode and CRTL select the four polys shown here. It is easier if you do this in the front viewport as they have to be symmetrical.
Press CRTL + R to rotate the viewport. now we use the extrude command and slowly drag the polys out.
Extrude again but this time a little less, then CRTL select the new inner polys. Extrude these and you should get this shape.
Extrude again until they are nearing toucjing then delete the selected polys.
Now we are going to have to weld the vertices together. This isn't as difficult as you would think, though. Hit CRTL + Q to activate Vertex Target Weld. Click on one vertex and drag it over to its neighbor. You will see a doted line appear from the selected vertex to the cursor which acts as a guide. It is very important to drag the vertex to its correct counterpart. I am left with 6 vertices, but they are a bit out of position. Change to the top view and move them so that they form a straight line. You can area select all of them and use the scale tool along the X axis.
The problem now is that it looks very boxy. Well the great thing about editable poly is that we can add a smoothing mesh on just one part of the object. Go into poly mode again and area select all the extruded polys while holding down the CRTL key. Now click on the 'Msmooth' button one. Rotate the viewport (CRTL+R) to see how it looks and click on Msmooth again if needed.
Now select all the polys around the edge and delete them.
Click the Mirror tool button (cirecled red) and change the axis to Y and Clone selection to copy. Another copy should appear. If you made the original cicle shape in the dead center of the viewport you shouldn't have to move them at all.
Click the 'Attach' button then click on the unselected half of the object to join them.
Switch to the top viewport and hit '1' to enter vertex mode. Area select all the vertices along the middle where the two sides joined. Now click on the 'weld' button.
All that is left to is add a litght and camera and a ground plane. I always use Vray to render my scenes. If you don't have it and you are serious about 3d, I would strongly recommend you to buy it.
