A note.
In this tutorial I used some tools, that are available only in version 4.0 an up. But with some minor changes, in some steps, same object can be also modeled in version 3.8.
*Before you start working, make sure that Snap to grid is on.
*The concept in the demonstrated technique, is to construct a simple nurbz surface, that more or less resembles our object and then to manipulate it to the desired shape.
*When I modeled this object I used an underlay image for reference.
1- Top view. Start with a simple line that I'll use as an axis for revolve.
Construct a polyline.
2- Generate a Spline from the polyline with the Curve tool (or use your favorite Spline tool)
Use the revolve tool to construct a derivative NURBZ object.
3- The result. You might need to rotate the object 90?
4- Use the convert tool to convert the object to NURBZ
5- Now this is the "Fun" part. Click on the object with the edit controls tool. Frame pick all control points and set the smoothens to off both U and V directions.
6- Side view. Now edit the object by moving the control point, without touching the control line that is perpendicular to the view\plan (be patience it take practice to do it right). As you can see this may lead to a problem, the object lost it's smoothens and a new shim appeared.
7- To solve the "problem" we will use the reconstruct tool (query and edit before version 4.0)
8- You might also need to add control line or lines to get the front view just right.
9- When you done, mirror copy the object and stitch both halves. This should result a solid object.
10- Side view. Construct a Polyline and a Spline and use the trim&stitch (with line) tool to trim the Solid object.
11- Now, the lower part is a simple extrude. Union it to the upper part.
12- The back side of the model isn't so "clean".
So I constructed a simple cube an Differenced it from the toilet seat.
13- To end up the job, some controlled smooth roundings.
14- and some smooth plain roundings.
 .
That's it
Good luck

So, Dan,
When are you going to bind your tutorials and make some money from them??
I am much appreciative that you take the time to share your knowledge here, so Thank you, Thank you, Thank you!

That's great Dan
I'm just blown away by peoples generosity when it comes to dedicating time for free to explain things to others who you don't even know!
I will play around with the ideas you have shown here.
Thank you Dan! |

Mission accomplished!
Dan I can't thank you enough, your tutorial does exactly what I need. My eyes are now open to a whole range of features I'd never even considered in Form Z.
You should take the book suggestions seriously. Your techniques and explanations are as good as any I've read.
Cheers,
Nik |

Dan,
actually I am annoyed that you make it look so damn easy  Just kidding...
You seem to have managed to do it in about half as many steps that I would have taken
I would definitely pony up some cash for a set of tutorials. Not that I am complaining about free stuff or anything, but you definitely deserve some compensation for your expertise.
Best

Thanks everyone
I promise nothing, but I'll see what I can do to publish some of my tutorials in hardcopy.
