Isometric Style Configuration - Rolling Offset Depiction

The configurations in this option (shown below) define the settings for a rolling offset. A rolling offset refers to a directional change (both vertically and horizontally) a pipe can make in a piping system. In a rolling offset:
  • Roll refers to the horizontal offset.
  • Rise (Offset) refers to the vertical offset

The image below provides a good visualization of how the offset is depicted in a model:

When an isometric is created offsets are depicted using hatched triangles/boxes such as the one shown below:

The settings below define how the rolling offsets are represented in the isometric.

Note: To apply the settings to a previously generated isometric, the user will need to save the Style Configuration settings and regenerate the isometric(s).
SettingDescription
Hatch Properties Hatching rolling offset triangles can be done in the following ways:
  • Full Hatching: When turned on, the entire offset triangle will be hatched as shown below:
  • Partial Hatching: This option will apply hatching to only a part of an offset triangle as shown below.

    How much of triangle is hatched depends on the Partial Hatch options defined.

  • No Hatching: No hatching is applied to the offset triangles.
  • Hatch Spacing: This determines the space between hatch lines using millimeters as the unit value.
  • Clearance: This value defines the distance the hatching lines will be pulled back from the run line graphics or any other graphic items (such as text, leader lines etc.) to give the isometric a clean look and let the graphic be easily viewable.
Partial Hatch Options When the Partial Hatch option is selected, the following options determine how the partial hatching is to be applied in the isometric.
  • Max Base Line Length: Limits the hatching to a defined distance along the triangle base line.
  • Max. Hatch Line Length: As the hatch lines progress in a triangle, the lines get longer. This limits the length of the Hatch Line length, thus limiting the amount of hatching displayed.
  • Max. Base Line Percentage: Limits the hatching to cover a percentage of the triangle base line.
  • Max. Hatch Lines: Limits the amount of total hatch lines. This option is also determined by the Hatch Line Spacing option as the smaller the spacing, the more lines that can be displayed.
The following example shows how these options can control the hatch display:
  1. Max Base Length = 25
  2. Max Hatch Length = 13
  3. Max Hatch Lines = 25 (Using 1mm spacing)
  4. Max Base Percentage = 25%
These settings would display in the isometric similar to the image below:
Hatch Symbology This Symbology defines settings for a hatch line.
  • Line Color - Define color of the hatch line. Click on browse button to open Color Table and select any color from the color table
  • Line Style - Select line style from the list for the hatch line.
  • Line Weight - Select line weight from the list for the hatch line.
  • Spacing (mm) - Sets the spacing between the hatch lines.
  • Level Name - Defines the level which the hatched offset will be drawn on.
Triangle/Box Properties The options in this section determine how offsets are depicted in the isometric.
  • 2D Skew - Use Box: When this option is turned On, a 2D offset is depicted in the isometric with a box as shown:

    When turned off, the offset is depicted using a triangle:

  • 3D Skew - Use Box: When this option is turned On, 3D offsets are depicted in the isometric with a box as shown:

    When turned off, the offset is depicted using a triangle:

  • Skew Branch: This option is only for branches. When enabled, the skew triangle/box only displays when the branch contains the defined minimum number of components. Otherwise a Direction Label is used.
Angle Annotation
  • Show inclined angles - Enable this option to display an angle value where triangles are used. The angle is always displayed in the first offset point.
    • Standout distance - Specifies the distance from the angle vertex to place the angle indicator.
  • Show Right Angle Indicator - Displays a right angle indicator box where right angles are used
    • Size (mm) - The size field defines the size of the right triangle box.
Triangle Symbology
  • Line Color - Define color of the triangle line. Click on browse button to open Color Table and select any color from the color table.
  • Line Style - Select line style for the triangle line from the list.
  • Line Weight - Select line weight of the triangle line from the list.
  • Hatch Spacing - Defines distance between hatch lines in mm.
  • Hatch Level Name - Select level from the list to define Level for hatches.
