silhouette / drillmount shape help!!

[chaoticneutral]

Looking for a hexagonal silhouette shape pattern number (or any pattern that's in pdf or printable with coordinates) drawn in crayon? that's fine! water colors? perfect! NO FINGER-PAINTING NEED APPLY! Yes, I have something personal against finger-painting. Don't ask.....there are some things that cannot be un heard. but seriously....looking for a shape pattern....thanks in advance.
something like this......except ... for glasses thanks.

[EyeCare Rich]

You want a hexagon? Or do you want an octagon like pictured?

[chaoticneutral]

Ugh! sometimes im so dumb, it's crippling. Extended octagonal like in the picture please. Thanks
<~~~ thats more like it

[chaoticneutral]

I called silhouette ... the got nuttin. making my own

[Hayde]

Good luck, CN!

Since you're winging it, here're my frames in case it helps: a CH205

[Boldt]

Talk to the lab, you'd be surprised what they can help with. Odds are it's not the first job like this they have had. (I once had one of my old labs make completely square ones and ones in the shape of Georgia just to win a bet.)

[chaoticneutral]

Thanks fellas, and after all that he wants to go with these

[EyeCare Rich]

Check out Silhouette Shape 4207. Pretty similar to Mr Hooper's there.

[chaoticneutral]

thankyou!

[DazeyReign]

The Studio Collection had a shape similar to that, 4207. And it took me so long to find my brochure I now see that someone already said that, but I'm going to post it anyway! I second!

[Barry Santini]

With an ICE 1000 tracer, you could create the shape you want with DESIGN cut. Make a plano sample CR-39, and trace that for normal beveling purposes.

Also, the Art Craft perimetric #1 and #2 bear a striking similarity. Your going to need a bigger blank.

[Speed]

That would be a 402-4 shape. Tell the lab you want to use a 402-2 shape. Best you determine at what level you want to place the holes for shilouette frame. We usually make the holes in 2 then 3 more for the second hole. 1.4 size holes. The level is the only variable. (how much over or below the 180). I know this would be no problem for us. Your lab should not have a problem with this.

[Hayde]

Your going to need a bigger blank.

ROFL!!! That one made my day.

To make things simple use a 60mm eye size to design and scale down through lab software.

Using the pattern center as the cartesian (0, 0) center for a right lens the critical points in a counter clockwise direction starting from the 180:

(30, 10)
(10, 30)
(-10, 30)
(-30, 10)
(-30, -10)
(-10, -30)
(10, -30)
(30, -10)

Those are your 8 corners, trace files are in polar coordinates so your have to convert those (x, y) values into radius and angles to create a R recordset.

theta= tan-1( x / y)
r = (x^2 + y^2)^1/2

Then create a TRCFMT recordset and specify mounting style rimless I assume and 8 radius and right lens.

That is a basic trace if 8 points are too low you could filling the remaining points using simple formulas for lines.

Radius goes in the R recordset and angles go in the A recordset.

TRCFMT=1;8;E;R;F
R=3162;3162;3162;3162;3162;3162;3162;3162
A=1843;71.57;10843;19843;25157;28843;34157

As you can see from the above code the radius of all the corners are the same as they should be. The points between the corners could be filled in with points the corresponding lines are function that should produce the (x,y) coordinates given the scenario above. Tip: restrict the domain and range. counter clockwise from right:

the vertical line on the right:
x = 30 {range of -10 to 10}

slope:
y = -x + 40 {domain 10 to 30 and range is 10 to 30}

top horizontal line:
y = 30 {domain of +10 to -10}

slope:
y = x + 40 {domain -10 to -30 and range is 10 to 30}

left vertical line:
x = -30 {range +10 to -10}

slope:
y = -x - 40 {domain -30 to -10 and range is -10 to -30}

horizontal bottom:
y = -30 {domain of -10 to +10}

slope:
y = x - 40 {domain 10 to 30 and range is -30 to -10}

Oh gawd. Here we go again. Why must people over think and over complicate things.

You have shown us that you can draw. Take a damn pattern blank draw your shape on it, cut it out and send it to the lab along with your order. If you do not have a pattern blank I am sure that the lab would be eager to supply you with one. When they receive your home made pattern they will take it from there.

All this garbage of "polar coordinates" "converting (x,y) changing values into radius theta=tan-(x/y)
r=(x^2+y^2)^1/2
Then creating a TRCFMT recorset and specify mounting style rimless.....................yata yata yata yata.
Gezzzzzzzzz im exhausted just looking at all that stuff.

wow grouch master flex ... he came here for help lets give him props for that instead of making him feel like a jerk! this is how we learn.

That was just to exercise the mind, the useful way as I have stated in past posts:

http://www.optiboard.com/forums/show...l=1#post196923

the method is to get heavy card stock and cut out the design with a scissor and trace it. I have been doing it that way for over 10+ years and now even the newer equipment will allow us to import an image and trace it, or use the blockers camera to create a design.

In the future I hope programming becomes more mainstream in the finish lab as it is in the surface lab.

[Don Gilman]

I have that in the original metal pattern. I can make a duplicate of it in heavy plastic if you like. EM me don@superoptical.com if you want it.

Thank you sir, may I have another.

A web designer can open a webpage in a text editor and change the layout of a site.

A computer programmer can do the same.

A machinist can open a NC file and make changes.

We have OMA files, its nice to have a knowledge of how these things work. For instance some manufacturer tracers will introduce code into these files so that vision web won't transmit. Open the file erase and your lab gets a trace. Vision web also won't give you certain edging options if the trace file is coded for let's say a groove instead of a standard bevel. If your using a POF you can either call the patient back to retrace, use software that hopefully allows you to change a setting, or change one number in a text editor. One current tracer that I know of on the market uses unequal angles for traces which are not accepted by visionweb, even though the actual angles traced are equal, again one simple change and your lab gets the file. The standard also makes mention of experimental record sets that start with "_" your machines might ignore it but you could be transmitting patient data, equipment data, etc. Software that works in the middle of the lab office transaction can be collecting data we're not aware of. Knowing this a simple scrubbing script can be run on a directory where trace files reside so only data that's necessary to produce the job is sent.

Just some examples of when opening up the file may help troubleshoot communication or transmission errors.
