Hidden Line Options

The OpenPlant Orthographics Manager separately generates 2D Hidden drawings that are generated by HSR (Hidden Surface Removal) processor. You can customize the Hidden drawing using the Hidden Line Options page shown below.

Accessed by selecting the Hidden Line Options node in the Settings interface.

The Hidden drawings will be written in an OpenPlant (DGN) format with the Level options defined.

Define the properties per the fields described below and Save the changes.

The Close icon closes the Project Settings interface, so make sure your changes are saved. You will be prompted to save them it you haven't already.

The Load Defaults icon in the main Settings interface will return the settings of the options page to their original values.

Selective Line Display

Use the following options to determine which type of Hidden Line representation will be used:

Setting	Description
Show Hidden line for all components	This option determines whether hidden lines will be created or not. If this option is disabled, then the hidden elements and levels will not be created. When checked, the Hidden Lines are displayed as shown (Red dotted lines): When unchecked, the Hidden lines are removed as shown:
Single Line	Pipe lines are displayed in Single line representation.
Double Line	All pipe lines are displayed in double line representation.
Both	Both Single and Double line types are used according to the pipe size. When this option is selected, it is used in conjunction with the following option: Any size above - is double line option: This value defines at what size the component is represented by a double line instead of single line using the following criteria: Double Line for any size greater than or equal to the value defined. Single Line for any size smaller than the value defined.

Pipe and Tee and Valve Options

The following options apply to the Pipe and Tee tab of the Hidden Line Options page (see image above):

The options in the Pipe, Tee and Valve tab define how those types of components will display in the Hidden Line drawings. Use the bitmap images for references when defining the settings. For some settings, the images are updated dynamically so you can see how they will be displayed.

Setting	Description
Pipe Hidden Options	If 2 single lines cross one another with different elevations like shown below: The gap distance can be defined using the following options: Equal to pipe OD: If it is selected, the gap distance of the lower pipe will be same as the pipe outer diameter. Fixed Gap distance: Define a gap distance in the Gap field. This applies the same gap distance to all hidden single pipes regardless of the pipe size. The fixed gap distance option is useful for the small single pipe or large single pipe because if the Equal to Pipe PD option is applied, it is more difficult to determine which one is the upper elevation. Show Center Line: Applies to double line representation. It determines whether the center line is displayed (as a dotted line) or not. Note: The bitmap image of this is updated dynamically as you toggle this option so you can view how it will display in the drawing. Include insulation thickness: Applies to double line representation. It determines whether the insulation thickness is included in the display or not. Note: The bitmap image of this is updated dynamically as you toggle this option so you can view how it will display in the drawing.
Tee Hidden Options	Show center line: Applies to double line representation. It determines whether the center line is displayed or not. Note: The bitmap image of this is updated dynamically as you toggle this option so you can view how it will display in the drawing. Distance A in inches: Refer to the bitmap image to define the gap size. Note: This setting is used to help identify a tee with a downward facing branch . Minimum size D in inches: Defines a minimum diameter. If the pipe size happens to be larger than what is entered here, this value will be used in the output.
Valve Hidden Options	The images in the Valve section shows how the valve will be displayed in a Hidden Line drawing. Show valve symbol: When enabled, OPOM will place the symbol from the Valvesymbol.cel file to replace the valve symbols found in the model. The cell data is stored in the C:\ProgramData\Bentley\OpenPlant CONNECT Edition\Configuration\Workspaces\WorkSpace\WorkSets\OpenPlantImperial\Standards\OpenPlant\OrthographicsManager\Cell directory. Define Symbols: Displays the Valve Symbol Data Dialog which contains the valve data used when placing symbols in the Hidden Line drawing. Custom symbols that are added to the ValveSymbol.cel file must be mapped to the desired EC class before they can be used in place of the graphics found in the model.

Pipe Hidden Options

If 2 single lines cross one another with different elevations like shown below:

The gap distance can be defined using the following options:

Equal to pipe OD: If it is selected, the gap distance of the lower pipe will be same as the pipe outer diameter.

Fixed Gap distance: Define a gap distance in the Gap field. This applies the same gap distance to all hidden single pipes regardless of the pipe size. The fixed gap distance option is useful for the small single pipe or large single pipe because if the Equal to Pipe PD option is applied, it is more difficult to determine which one is the upper elevation.

Note: The bitmap image of this is updated dynamically as you toggle this option so you can view how it will display in the drawing.

Tee Hidden Options

Show center line: Applies to double line representation. It determines whether the center line is displayed or not.

Note: The bitmap image of this is updated dynamically as you toggle this option so you can view how it will display in the drawing.

Distance A in inches: Refer to the bitmap image to define the gap size.

Note: This setting is used to help identify a tee with a downward facing branch .

Minimum size D in inches: Defines a minimum diameter. If the pipe size happens to be larger than what is entered here, this value will be used in the output.

Valve Hidden Options

The images in the Valve section shows how the valve will be displayed in a Hidden Line drawing.

Show valve symbol: When enabled, OPOM will place the symbol from the Valvesymbol.cel file to replace the valve symbols found in the model. The cell data is stored in the C:\ProgramData\Bentley\OpenPlant CONNECT Edition\Configuration\Workspaces\WorkSpace\WorkSets\OpenPlantImperial\Standards\OpenPlant\OrthographicsManager\Cell directory.

Custom symbols that are added to the ValveSymbol.cel file must be mapped to the desired EC class before they can be used in place of the graphics found in the model.

Elbows Options

The options in the Elbows tab define how the Welded and Socket Welded elbows will display in the Hidden Line drawings. Use the bitmap images for references when defining the settings. For some settings, the images are updated dynamically so you can see how they will be displayed.

Setting	Description
Weld Type Elbows	Show Center Line: Toggles the center line On/Off for the elbow. Note: The bitmap image of this is updated dynamically as you toggle this option so you can view how it will display in the drawing. Show Cross Line: Toggles whether the cross line (extension of the center line to where it would intersect) is displayed on pipe bends. Note: The bitmap image of this is updated dynamically as you toggle this option so you can view how it will display in the drawing. Distance A: Defines the distance beyond the intersection point the cross line will extend for single line representation. Distance B of OD: Defines the distance beyond the intersection point the cross line will extend for double line representation. The value of this option is the scale factor of the pipe's outer diameter. Angle C in degrees: It is the opening angle when the elbow goes upwards. The default value is 30 degree. Minimum size D: Minimum size for a non 90 Degree Weld Type Elbow. Weld dot size: If a Weld dot is used as a weld symbol, this option defines the size of the dot. Elbow corner type: Only Round corner type is available for the Weld Type Elbow.
