Setting manually of cut layer in any position of diamond.

It is necessary to have any model for work with Layer.

Step 1. Create ordinary object Layer.

Click on the button by the right click of the mouse in the panel Objects for the model in Scene. Choose and press New plane.

Step 2. Make Layer as operated by user.

Click on the button by the right click of the mouse in the panel Objects for the Layer. Choose and press Set layer position by handle. Thus you create new object Tune: Layer.

Step 3. Set Layer in the necessary position.

Position of Layer is defined by four methods:

• One cross - moving of Layer in the horizontal plane (Figure 1)
• Two crosses - rotation of Layer relatively one of cross-points in the screen plane (Figure 2)
• Three crosses - Layer passes through 3 crosses - rotation of Layer relatively line which passing through two crosses of three (Figure 3)
• Four crosses - Layer is defined by the way of minimization of mean-square distances between points (crosses) and Layer

Figure 1. One cross Moving of Layer in the horizontal plane Click and hold by the right button of the mouse in the area of model. In such way you create first marker (a cross into the circle, the circle is the area of capture). Move the mouse cursor in the area of the cross (you should see circle - area of the capture), then press the button of the mouse and move the plane at the necessary horizontal level. Release button.

Figure 2. Two crosses Rotation of Layer relatively one of cross-points in the screen plane Create the second cross by the same way. Hold one of crosses and move in the necessary position controlling the slope of Layer in the plane of the screen, then release button.

Figure 3. Three crosses Layer passes through 3 crosses - rotation of Layer relatively line which passing through two crosses of three Create third marker by the same way. Capture one of tree crosses and rotate Layer relatively line which is lied through two other crosses.

Four crosses Layer is defined by the way of minimization of mean-square distances between points (crosses) and Layer Create forth marker and change it's position controlling Layer position.

When you created Tune: Layer you see information on the top corner of Scene (Figure 4). You can switch off- switch on this visualization of information by the pressing on the first button near new inscription Tune: Layer in the panel Objects.

Figure 4

The 3rd and 4th methods are wide applied during checking of existed (created by signer manually on the real diamond before) marking layer.

There is short description of this process:

1. Planning of diamond manually by the pen - create marking layer.
2. Scanning and building of model of diamond on 3D scanner.
3. Rotate diamond in position with good view of line. Repeat operations 1 - 3. First described upper - create first cross on the line (Figure 5, a).
4. Then in the same position create second cross (Figure 5, b).
5. Rotate stone with help of motors to see opposite side of layer.
6. Create third cross (Figure 5, c). So you set object Layer in correct position.
7. Press Close in the panel of objects near object Tune: Layer.

Figure 5, a. First cross

Figure 5, b. Second cross

Figure 5, c. Third cross

Remove any cross.
You can remove any cross by the next way: move the mouse cursor in the area of any cross, press by the right button and choose Remove point.
