DRAWING RECOVER Mode Control

        

FEMGEN and FEMVIEW only.

This command allows the user to access for further examination a particular drawing of the model previously saved with the DRAWING SAVE PLOTFILE [filename] and the DRAWING SAVE LIVE commands.

Mode Control Comments

PLOTFILE filename Recovers a formatted plotfile provided it has been saved in the neutral plotfile format (see note 1).

LIVE number (FEMVIEW only) Recovers the specified `live' drawing which has been saved in the database (see note 2).

OVERLAY filenames (FEMVIEW only) Recovers and superimposes plotfile pictures (see note 3).

Notes:

1.

Re-viewing plotfiles
With the DRAWING RECOVER PLOTFILE [filename] command, the plotting information is read from the named file in which the drawing is specified as a sequence of moves and draws, colour changes, etc. This will regenerate a `frozen view' of the model and/or results. The user cannot go on to work with this view within FEMGV, but it is useful for reference purposes, and it will display the picture that would be produced if a user were to access this file for the purpose of obtaining a hard-copy plot. Pictures that have been generated in the format specified in Appendix E of the User Manual Appendices but have been generated by a program other than FEMGV can be displayed in this way.

2.

Recovering `live' drawings
With the DRAWING RECOVER LIVE command the sequence number of the drawing within the drawing index will be used as the control to specify the view to be reproduced. A parametric description of the view will have been saved, and the drawing is regenerated from the model and results data stored in the data base. This will regenerate a `live view' and the user may go on to e.g. apply a rotation, or adjust the presentation of the results.

3.

Overlaying plotfile pictures
The command DRAWING RECOVER OVERLAY allows the user to superimpose pictures that have been written to formatted plotfiles.

Examples:

1.

DRAWING RECOVER PLOTFILE PISTON.PIC

The plotfile PISTON.PIC will be read and the drawing reproduced in the current viewport.

2.

DRAWING RECOVER LIVE 5

The parametric description of the drawing number 5 in the drawing index will be accessed, and the drawing will be regenerated in the current viewport.

3.

DRAWING RECOVER OVERLAY f1 f2 f3 f4

The named plotfiles are read and are superimposed.
