hfss surface tetrahedrons
How do you draw a tetrahedron in HFSS ? or for that matter a tapered structure ( like the flare of a rectangular horn ) in HFSS ? Thanks for your time.

You can convert 2D objects to 3D objects.
For example by closing a 3D surface and convert it to a 3D object
or by sweeping using 1 or 2 surfaces.

Can you be a little more specific. When I try to use sweep,Iget the following error :
Acis error: "Failed to sweep the object."
I don't know what to make of this.

Actually my english is not so well, so I am not sure what is a tetrahedron.
Do you mean a triangular pyramid ?
Itai
Yes most definitely I mean Triangular Pyramid. Well I guess I need to know how to draw any pyramid (except a cone which already a menu item in HFSS ) be it wtih trianglular base or a general polygon as the base. Thanks

Here goes...
First, define the following variables (so it will be parametric):
shape (base polygon shape - 3 for traingle)
radius (base polygon radius)
height (pyramid height)
angle = atan(radius/height)
The angle will be used in the sweep operation.
Second create a new rectangular polygon.
Use the shap and radius parameters
Then sweep it along the a vector in the Z direction.
Manually change the sweep parameters to (0,0,height) and set the draft angle = -angle (minus angle).
Thats it you're done.
See the attached hfss project for an example.
