I want to make a lens that is a cover of an LCD Display Segment.
I wish I could attach a bitmap image to this posting to describe the shape....
The lens cover is rectangular with the left and right side being semi circles.
Top View.

I would imaging that this would be like revolving a log curve around the x-axis and reflecting it at width / 2.
How do I go about doing that?
Or could I define a bezier conic and revolve that about an axis? |

Hi,
I'm not sure about the right model you're looking for ( in the side view, I don't understand the bottom line "------------"). You can however try this isosurface at different grid resolution (61 for example) :
| Code: | Name: Lens
F(): -if((abs(z)<0.5) & y<0,-((x*x + (y/0.1)*(y/0.1) + z*z - 1) ) ,(x^10 + y^10 +z^10 - 200000))
[x]: -1 , 1
[y]: -1 , 2
[z]: -.6 , .6

Save it as .k3ds file and load it in K3DSurf
NB: cut the "& y<0" part of the formula to have a shape like the top-view
