Hi,
This should be possible:
1. Start a 3D model.
2. In the Geometry branch, add a Work Plane.
3. In the Work Plane's Plane Geometry sequence, add a Polygon node with the following settings (to create a simple hexagon):
Type: Solid
xw: 0 sin(angle) sin(2*angle) sin(3*angle) sin(4*angle) sin(5*angle) 0
yw: 1 cos(angle) cos(2*angle) cos(3*angle) cos(4*angle) cos(5*angle) 1
where angle is a parameter that is defined as 60[deg].
4. Right-click the Work Plane node and choose Extrude.
5. In the Extrude node's settings window, enter an extrusion distance under "Distances from Plane".
6. Click Build Selected or Build All.
Hope this helps,
Magnus Ringh, COMSOL

thanks a lot, sir! !!!!!!!!!!
it was very helpful instruction set to build a prism.
please give me an instruction set to coat a layer of prism with another material.

Hi!
we need to model a high frequency horn. It has hybrid flare, the xy cross section has exponential flare and yz cross section has a conical flare. Is there a way to extrude it using exponential and linear function?
Thank you.

Hi Feruza,
I don't believe you can create that shape using an extrusion because of the exponential flare. The interface for extrusion supports conical flares only, as far as I know. But an alternate approach would be, if your base cross-section is a simple one, to use a parametric surface -or several parametric surfaces if needed. Another idea, if your license includes the Design Module, would be to loft a surface over several parallel cross sections.
Best regards,
Jeff
