- Under the analysis tab,
I have a tool called deviation gauge.
When you're creating your primaries and secondaries,
you want to make sure you're creating them
to within a tolerance based off of
the quality of the scan
or the curve that you have, and the best way to do that is
with the deviation gauge.
You pick the surface that you've created,
and then you pick the reference object.
In this case, I have scan data.
This is a facet body.
Measure definition is just simply 3D, leave it at that.
If you want to measure based off of a vector,
or the WCS, you can do that.
You can specify in the vector direction.
For us, we'll just leave it at 3D.
You can go ahead and close that out.
Plots, this is the needles.
Maybe you want to see where the deviations
are at across the surface to the scan
and this gives you
a nice gradient, shows you what's going on.
You can see that it's positive and negative,
and positive and negative,
so it's coming in and out of that scan.
You have the ability to turn the needles off.
Sometimes I like to look at them,
and sometimes they just get in the way.
So, I like to get an idea of where things are located at.
I have down here my label for maximum turned on.
I like to see where my maximum is at.
Sometimes it's nice to the see the needles
as you're manipulating,
but they can be a little crowding at times.
So, being able to turn them off quickly is nice.
The suggested scale factor is, you notice,
that as I zoom in and out, the needles automatically scale.
I can turn that off,
maybe you don't want to leave them a specific height,
so this is that heighth,
helps to clean up the screen a little bit,
and if you don't want to see needles at all,
you can turn 'em off, go to Markers.
Markers are just little markers on the surface
indicating where the deviations are at
and you also have a color map.
So, this color map is showing you,
"Hey, these are my positive and my negative,
"this is within a tolerance,
"what's outside of this tolerance," et cetera.
The greater the distance, you can see here,
the darker the red, and so on.
I have it set to absolute value.
If I turn that off,
absolute value isn't going to show everything in positive.
So now, the green is set to my zero,
so everything within that tolerance band is in green
and the greater the distance away,
we get into the reds and the blues
at the opposite ends of the spectrum.
If I come down here, and look at my tolerance,
maybe I'm wanting to work to half a mil
in the outer, positive outer,
half a mil in the positive inner,
and the same thing with my negative outer,
and as you can see, the color gradient begins to change
based off of the numbers that I've just input.
So, if I know that I'm working within a quarter of a mil,
I just come over here, specify quarter of a mil,
you can see it's changed in both of those.
Come over here, a quarter of a mil.
It's changed both of those, and it shows me my gradient.
So, these are the areas that I could focus on
that are outside of that quarter of a mil deviation.
Let me go ahead and close this, close this.
Another option that I have for reporting out
the tolerance value is location.
So, under the location I have the ability to pick a spot
and get that value.
So, if there's a specific location you need
to know the distance of,
even though it may be within tolerance,
or maybe it's something that you want to take out of tolerance
because it's a bad spot, or a stylist is asking
for the reflections to move a different way,
but you have to keep it within a certain tolerance band
even though it's greater than the allowable.
Technically, sometimes that happens.
You can come in and set up that specific location
using that deviation label here,
and down here is just error reporting,
giving you an idea of how many samples,
as well as the tolerance swings
and out of tolerance samples that it's taken.
So, this is just a handful of them.
So, those are, as you can see here and here.
