<div class="moz-cite-prefix">Hi Tyler,<br>
it is correct. The points ABCD are not on the same plane.<br>
Only the lateral side are planar surfaces.<br>
Best regards<br>

<div>We have been looking at mirror C3 and are still having
problems with the corners of the ideal model being
non-coplanar. We have looked at the data in NX 9 and AutoCAD
and in both we see one corner not lying in the plane created
by the other three. Attached is an image generated in NX 9
showing this. The plane was created using corners A, B, and C
and you can see corner D is above the plane. We see a similar
thing in AutoCAD.<br data-mce-bogus="1">

<div>I have also taken your advice in the email from this
morning and checked the cross product of the two diagonals
with each side. From this, we do not get that the corners of
mirrors C3 and C4 are coplanar. However, we do see that
mirrors C2 and C5 have coplanar corners. We are very puzzled
by this. Do you have any idea why this is? The only thing that
we can think of is that the step models for C3 and C4 are
somehow incorrect when we import them. Could you please send
us the raw model files and also just the coordinates for the
corners that you used for your calculations? Thank you in
advance.<br data-mce-bogus="1">

<div>Also, by the way, I sent an email to Walt Akers today to
ask of any progress on the space layout of EEL 124 to ensure
that there will be adequate space for the RICH assembly and
testing. I will send his reply and the model for the area with
the mailing list when I get it.<br data-mce-bogus="1">
