CHAPTER 14

14 Plate Jigs

14.1 Description

This module will produce plate jigs for curved panels at user defined positions from a seam.

Basic data for calculation are curved panels stored in the data bank. The main results of the system are listings, sketches and plate parts stored in the plate database.

The executable sf821d calculates jig information for curved panels established by input data.

14.2 Control of the program 14.2.1 Configuration file

The program is controlled by system variables assigned in the project file and the contents of the default file platejig.ip located in the SB_SHIP directory.

For a full list of all possible input parameters in the file, and an explanation for each, please refer to the AVEVA Marine Documentation, Hull Detailed Design, Manufacturing, Curved Plates, Plate Jigs, Set-up of Program, Control Information.

14.2.2 Sketch Configuration

The output from the program consists of two sketches for each plate jig arrangement. One of the sketches is a formatted drawing and therefore requires a drawing form named TB_PLATEJIGS to exist in the

SBD_STD.

For a full description of the contents of the two drawings and a list of all possible drawing rules with an explanation for each, please refer to the AVAVA Marine User‟s Guides, Hull Detailed Design,

Manufacturing, Curved Plates, Plate Jigs, Result, Drawings.

14.3 Running the program

To start the function a drawing must be current in AVEVA Marine 12, Hull Detailed Design – Planar Modelling or Curved Modelling application.

Use the command Hull Tools>PPI Hull>Bending Templates and Jigs Select Plate Jigs The following form will be displayed:

Panel name: Will display the name of the selected curved panel.

Jig Row Position: Defines the alignment of the plate jigs (on either a frame or waterline plane).

Def. Ass. Plane:

Default: The assembly plane is calculated as defined by the ip AUTOMATIC_ASSEMBLY_PLANE, i.e. either by the corner points of the panel or by the midpoints of the boundary seams.

Y: The assembly plane will be parallel to a buttock plane.

Z: The assembly plane will be parallel to a waterline plane.

www.aveva.com

3 Points: Requires the user to give three points that define the assembly plane together. The points must not be co-linear. By selecting 3 Points followed by the Next button the form shown opposite will be displayed.

After completing the 9 fields click Next to proceed.

The system will display the prompt: Indicate seam from which distances will be calculated - Cursor position.

Click the edge of the curved panel that you wish the resulting plate jigs to be measured along.

The system will display the prompt: Indicate seam for the jig row position – Cursor position.

Click the edge of the curved panel from which the plate jigs will be parallel, this will always be perpendicular to the edge selected to measure along.

The system will display the following window:

Key in a value, this is the distance parallel to the seam you have just selected. Select OK The system will again display the prompt:

Indicate seam for the jig row position – Cursor position.

Continue to select the seam you wish to place your plate jigs parallel to The system will again display the following window:

Key in a value, this is the distance parallel to the seam you have just selected. Select OK

You can continue to select the seam and key in distances to suit your required output (note: if a value is given which is not on the curved panel, the program will not run and an error log will be generated).

After you have selected OK to your last required input select Operation Complete, the program will now run, (if Production Information was not selected).

Monitor the progress of the job in the Log Viewer and when the job is flagged as terminated the results can be viewed. If Production Information was requested the form shown in paragraph 12.3.1.1 will be displayed.

Please refer to paragraph 12.3.1.1 for further information.

14.4 Output

The Plate Jig program produces text output regarding the running of the job and plate jig information as well as a sketch output for use in production.

14.4.1 Text output

Four text files should be produced as a result of running the Jig Pillar program. All files should appear in the SB_SHIPPRINT directory of the current project. The files can be opened by double clicking them in the Log Viewer.

stdout<computer name>_<job number>.txt

Contains information regarding the execution of the program.

stderr_<computer name>_<job number>.txt Not applicable for the user. Internal system file.

platejigs0 _<computer name>_<job number>.log

Contains information regarding the systems interpretation of the objects selected as input to the program.

platejigs1_<computer name>_<job number>.lst

Contains information for the plate jigs themselves as well as positional information.

14.4.2 Sketch

The system creates two sketches. These sketches are stored in the database assigned to

SBH_PLJIG_DWG. The sketch outputs are named according rules defined in SBH_DWGNAME_RULE, for example:

pjig_<computer name>_<job number> <sheet number>(total No.)

To view the sketch outputs during the current session of the application use the following command, Hull Tools>PPI Hull>Show.

Select the relevant job name, press the Open button to view it.

At any other time this plot can be opened as a standard drawing by selecting File>Open then selecting Type: Hull plate jigs drawing, using a wildcard in the Name box will allow all plate jig drawings to be listed.

14.4.3 Example

The notches are to allow access in way of the plate seams, there is also an alignment mark in the notch directly below the seam.

These plates are stored in the plate database for use in the Nesting application, and are named as follows

<Panel name>-<Row><Position> as shown below.

Exercise 12

1. Open the HULL_PROD_EXERCISES drawing.

2. Select the curved panel shown below (F206-CP02) and use the function Plate Jigs.

3. Create plate jigs at distances 1500, 3000, 4500, 6000, 7000 from the aft end of the panel. The input file which can be viewed in the Log Viewer.

Select seam MTPS302 for distances measured along (first selection)

Select butt MTPS113 as parallel to jig rows (second and subsequent selection)

4. Review results.

CHAPTER 15

15 Hull Marks

15.1 Description

This module will produce plate parts and marking lines to allow manufacture and placing of marking contours that intersect the shell. (waterline markings and nameplates etc.)

Nameplates and waterline marks that appear on the shell of the ship can be created as plate parts (structures), or as marking lines that can be embellished with bead welds to indicate the contour of the character. Symbol font 99 is the default font used for marking texts, ensure that all characters that are required exist in the symbol font table.

Application setting to be changed to Planar Modelling to perform Hull Marks. File>Planar Modelling.
