This function is used to calculate the outline of the blank on the binder (un-deformed blank) and estimate the size of blank. The estimation is based on the trim line on the part after forming or springback simulation. The steps are listed below.

1.       Read in d3plot files from the DYNA analysis.

Read in a line data file as the trim line by using the IMPORT function in the FILE menu. The line data file should only consist of trim line(s). The trim line can also be created by using the CREATE LINE function in the EDIT menu.

2.       Select BLANK OUTLINE from the icon bar.

The Control Option Window is shown in Figure 8.13.1. Click SELECT BY CURSOR to select trim line(s).

3.       After the desired trim line is selected, click EXECUTE to calculate the Blank Outline.

NOTE:      If there is no line defined in the database, the program will display a warning message “NO LINES IN DATABASE.”

The selected or created trim line will automatically map on the original (un-deformed) blank for the user to estimate.
