About Creating Cooling Circuits with the Waterline Designer
Use the Waterline Designer to speed up the process of defining waterline circuits.
It takes fewer clicks to create waterline leading curves and the entire system of cuts and cooling components.
1. Click > 
Waterline Designer.
Waterline Designer.The Waterline Designer and the Select dialog boxes open.
The Waterline Designer dialog box contains the two tabs described below:
◦ Design—Contains options for designing cooling circuits with the waterline.
◦ Options—Contains filters and options to help you design the waterline.
2. In the graphics window, select a list of the cavity plates where you need to define waterline circuits and then in the Select dialog box click OK.
The Select Working Models list is populated.
 | You can create cooling circuits within just one working model, or between plates in multiple working models. |
3. In the Design tab, click the Select Working Models box, and select your active working model.
The active working model is the model in which you can define, modify, or delete waterlines.
In the Select Working Models area of this dialog box you can perform the actions described below:
◦ To change the active working model click 
, select the model in the graphics window, and then click OK in the Select dialog box.

, and in the graphics window select the plate you want to add.The simplified representation is temporarily not visible.
Click OK in the Select dialog box and the complete mold design appears.
4. Use the Sketch Planes table to manage your sketch planes.
A sketch plane contains a Z position. The Z position of the drawing plane is measured from the coordinate system ORIGIN_MOLDBASE which must be present in the Creo Expert Moldbase mold base assembly.
A sketch plane is valid only if a waterline is defined on it. Sketch planes without waterlines are automatically erased by the Waterline Designer.
◦ To add sketch planes click . By default, the added sketch planes are placed in the middle of the model.

▪ From the <EMX_loadpoint> open the configuration folder. In the configuration folder open bore_technology.cfg.
Scroll to the waterline_analysis_color entries and made additional entries, such as waterline_analysis_color11.
The additional waterlines appear in the Cooling Circuits table.
◦ In the 
diameter column, the diameter of the cooling circuit appears.
diameter column, the diameter of the cooling circuit appears.This value is the designated diameter of the cooling circuit.
If you change this value all nominal waterline bores in the cooling circuit are adjusted.
| | All cooling bores in a cooling circuit should have the diameter value that is listed. In Creo Expert Moldbase, the cooling bore diameter is usually defined by the selected component in the Component dialog box. You can manually change the value of the cooling bore later, but as a result, the component and the cooling bore diameter may not fit together. Therefore, you should avoid changing the diameter of the cooling bore manually for the components defined with the Waterline Designer. |
6. Click the Options tab to set snapping rules and collision control to support your waterline creation.
◦ Select or clear the check boxes under Snap Rules for support during your waterline creation process.
The Waterline Designer recognizes all previously created waterlines and helps you to define new ones based on their positions.
The Waterline Designer supports snapping to knots and waterlines.
It also helps you to create waterlines that are orthogonal, symmetric, or directly on or to the ORIGIN_MOLDBASE.
◦ If the Collision Control check box is selected, and the waterline intersects any cut within the plate when moving the pointer to select the second point, the waterline appears in red.
If no collision is detected or the Collision Control check box is cleared, the waterline and the inlets appear in the color associated with the cooling circuit.
In the Stock allowance box, you can change the value that represents the minimum allowed distance to the next hole in the plate.
7. In the Design tab, below the Cooling Circuits table, there are buttons for creating, modifying, and deleting waterlines and for assembling predefined components of waterlines.
As you create waterlines, the waterlines for the currently selected working model appear in a list on the right panel of the Waterline Designer dialog box.
For more information on the list of waterlines, go to step 9. The steps for creating, modifying, and deleting waterlines and for assembling predefined components of waterlines, are described below:
