Background

In Plant Piping Isometrics, it is certain that pipe should route at various angles and may fall at different coordinates. To present these directional changes in piping systems rolling graphics Box/Triangle shall be used. OpenPlant Isometrics Manager features such capabilities to allow user to display these rolling offset in various ways. Below description will aid user to deliver desired output. This should work in context with both OpenPlant Modeler-OpenPlant Isometrics Manager & AutoPLANT Modeler-OpenPlant Isometrics Manager. However below has been illustrated in context with OpenPlant Modeler & OpenPlant Isometrics Manager. 

Below is the default Isometric Configuration dialog with Rolling Offset Depiction option.

                   

See Examples below

• For Hatch Properties

Example: Line Color – Line Style – Line Weight

User can set line color, style & weight etc as per project requirement. 

Example: Spacing – Hatch Spacing can be adjusted which is in MM by default.

Example: Level – User can set different level of his choice here

• For Triangle/Box Properties

Example: 2D Skew – 3D Skew
Setting Triangle Type gives a Triangle graphics along with pipeline. See below image with settings.

In Isometric Configuration for 2D-3D

          

In Isometrics:

 

Setting Box Type gives a box graphics along with pipeline. See below image with settings.

In Isometric Configuration for 2D-3D

In Isometrics:

Example: 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.

Example: Line Color-Line Style-Line Weight-Level Name

       

This will aid user to change box/Triangle symbology.

Example: Angle Annotation & Right Angle Symbol.

In Isometrics:

After changing Inclination angle as 30 & Right Angle symbol as 10

In Isometrics:

Also see below steps to change Right angle Symbol size

Steps to Accomplish

For OpenPlant Isometrics Manager Version SS6 (08.11.11.87)

1. Launch OpenPlant Isometrics Manager. Select Project unit, say Metric here.
   
   
2. Click on Configuration to launch ‘Isometric Configuration’ dialog box.
   
   
3. From “Rolling Offset Depiction” option, check Angle Annotation option.
   
   
4. Change symbol size from 2 mm to 10 mm as shown in below image.
   
   
   
   
5. Save changed option.
   
   
6. Generate Isometrics and verify results. See image below: 
   
   

For OpenPlant Isometrics Manager Version SS5 (08.11.09.574)

For SS5 release, there is no option present in Isometric configuration dialog to change the settings. However it can be done by modifying style.xml file. See below steps to check. 

1. Launch OpenPlant Isometrics Manager. Select Project unit, say Metric here.
   
   
2. Click on Configuration to launch ‘Isometric Configuration’ dialog box.
   
   
   
   
3. Open Style.xml file.
   
   
4. Add below expression to it like shown in below image.
   
   <PerpBoxSize>10</PerpBoxSize>
   
   
   
   
5. Save changed option.
   
   
6. Generate Isometrics and verify results. See image below:
