Clash Plotting

Generates drawings of clashing Model items using a special Model Clash Report Macro file, which is generated using the Clash Detection facility available from within the Model module.

Refer to Clash Detection for further information.

The items selected for clashing in Model must be named elements, otherwise clash plotting will produce errors.

The Model Clash Report Macro file required by Draw is generated using a special template file dra-gen-clashtemp, which can be found in the System Defaults folder %AVEVA_DESIGN_DFLTS%. It contains instructions for creating the drawings, which can be modified to suit the your needs;

var !!CDCLANUM |$CLANUM$|

var !!CDCLA1 |$CLA1$|

var !!CDCLA2 |$CLA2$|

var !!CDCLAPOS |$CLAPOS$|

var !!CDCLATEXT |$CLATEXT$|

var !!CDCLAOWN1 |$CLAOWN1$|

var !!CDCLAOWN2 |$CLAOWN2$|

The instructions are used to extract Clash data and organise it in a format needed by the PML program file UCLASHPLOT, which ultimately creates the drawings. Data is extracted whilst running the Clash Report using special keywords. For example, the Clash Number is extracted using the keyword CLANUM. Because of this, any changes you make to the template file must adhere to the format as defined by the program file.

Normally, the Model Clash Report Macro file is produced using a macro, for example:

-- In the Model module enter the mode DESCLASH

DESCLASH

-- Generate the Clash Data

REM OBST ALL

OVERRIDE ON

OBST /80-B-7

OBST /100-A-15

CHECKADD /EL(+)107820_TOS

-- Generate the clash report macro file for input into DRAW

-- This uses the report defaults file as discussed above

REPORT MACRO /%AVEVA_DESIGN_DFLTS%/DRA-GEN-CLASHTEMP

ALP FILE /%AVEVA_DESIGN_USER%/CLASHES-DRAFT.MAC OVER

OUTPUT

ALP FILE END

REPORT MACRO OFF

-- Leave the mode DESCLASH

EXIT

The resulting Model Clash Report Macro file contains instructions for creating the drawings in Draw.

Example of the data for the first Clash reported by the Model Clash check made:

var !!CDCLANUM |1|

var !!CDCLA1 |PANEL 1 of SBFRAMEWORK /EL(+)107820_TOS_PLATE|

var !!CDCLA2 |leave tube of ELBOW 1 of BRANCH /100-A-15/B1|

var !!CDCLAPOS | W311586 N294516 U107821|

var !!CDCLATEXT |HH PANEL 1 of SBFRAMEWORK /EL(+)107820_TOS_PLATE with leave tube of ELBOW 1 of BRANCH /100-A-15/B1|

var !!CDCLAOWN1 |PANEL 1 of SBFRAMEWORK /EL(+)107820_TOS_PLATE|

var !!CDCLAOWN2 |BRANCH /100-A-15/B1|

CALLDRG UCLASHPLOT

These instructions tell the PML program what data is to be placed on the drawing for each particular field. The data is located on a drawing as defined by a Clash Plot Sheet, an example of which SHEE /DRA/PRJ/TMP/CLASH/A3/S1 is supplied with the product. It is recommended that you copy the owning DRWG of this SHEE element to a suitable location and rename it before using the Clash Plotting utility. The sheet references a Backing Sheet that contains special keywords that takes the Clash Data from the Model Clash Report and displays it on each drawing created using the Model Clash Report.

Example of the supplied backing sheet BACK /DRA/MAS/BACKS/MET/A3_Clash.

The special keywords positioned on the backing sheet match those keywords used to extract the Clash Data during the creation of the Clash Report.

Note:
The Clash Plotting Utility looks for a NOTE element below the BACK named <backing sheet name>/CLASHDATA.

The NOTE contains all of the required Clash Data keywords, the visibility of which must be set to Off to prevent the keywords themselves from appearing on the final drawing.

The keywords available for extracting and placing Clash Data on drawings are:

Once you have created the Model Clash Report Macro file in the Model module, you can create the Clash drawing in Draw using the Clash Plotting window.

The Clash Plotting window allows you to define the settings used for the Clash drawing.
