Modeling an Precision Elliptical Flat Mirrors

Okay,

I'm certain it's because I'm a buffoon, but I have no idea how to
model the mirror shown in Figure B here

Scroll all the way down.

Any suggestions?

TIA

There looks to be some missing info, such as what the edges do around
the sides, but here's one take on it:

www.dezignstuff.com/swparts/part1.SLDPRT

2006 format

I just extruded an ellipse along an angled line, and then cut away part
of the outside. The cut creates a funny edge, but it fits the info given.

 

extrude a cylinder, dia = minor axis
cut disc from side of cylinder. (hint 45 deg)

i can't post , so i sent you a sample.

that's it.

it's preferable to have origin on surface to make it easy to calculate focal
distances.

 

Great,

Thanks guys!

Oooo... as a reminder, when drawing mirrors/lenses watch your units!
