Help , HFSS 9.0 and above drawing non rectangle 3 D objects.

I have been having a hard time to draw anything 3D that is not a standard shape. Like for example drawing a three D triangle. Ican make a 3D line but not sure on how to change that to a 3D object. I have read help files but no avail on that end. I tried using the planes to cut out either negative or positive side but it has not been that graet.

Side note, this is my first time using HFSS and have had to model a certain internal antenna for mobile phone applicaiton.

What do you mean by 3D triangle. Is it a tetrahedral?
Try 3D modeler>faces>cover faces

See attached jpeg. IT is a 2-D triangle with height=0 that I made by drawing a polyline, and then followed your instructions on to "cover face, but I want to make a 3-D model for example a height of 2
