In the practical nesting process, besides
the above mentioned nesting methods, there are five other methods added in
eta/DYNAFORM: Rectangle Nesting,
Rectangle Nesting enables the user to generate the nesting result by embedding the blank in a rectangle. Refer to One-up Nesting and Two-up Nesting for a detailed description about parameter setup and operations. The options of manual are different from the ones of the above mentioned nesting methods, as illustrated in Figure 6.6.27.

Since the cut-off profile is used to fit the blank, the master and slave blanks are not considered here. In the cut-off profile nesting, the Select Blank option is disabled and only the rotation buttons are enabled for the user to adjust the blank position.
After the user estimates the part outline (MSTEP), selects the rectangle nesting type, and performs the nesting calculation on the outline, the result page is illustrated in Figure 6.6.28. The Calculate Addendum button is available now.

This button is only highlighted when the
user uses MSTEP and selects Draw Nesting Type for pitch scaling. Select one
result of the nesting calculation, and click
Calculate
Addendum
This button is only activated when the
user selects Draw Nesting Type. Click
Compensating Rate
Compensating rate is used to calculate a coefficient of addendum, and the default is 0.8. The user is allowed to modify the value, or edit the default in Default Config.
Addendum
The program can automatically calculate an appropriate addendum according to the empirical formula by empirical formula according to the current nesting result (Pitch and Width) and compensating rate. The user is not allowed to modify the addendum value.
Click Apply button to obtain an appropriate Addendum value. Click Exit button to exit this dialog box. The program will automatically put the calculated addendum on the Setup page for the user to redo the nesting calculation according to this addendum.

Blank Outline
This button is only activated when the user selects the second row in Draw Nesting Type. Clicking Calculate Blank Outline button, the program will automatically generate blank outline according to the currently selected Draw Nesting Type, including rectangle, parallelogram, trapezoid, isosceles-trapezoid, and arc outline. The calculated outline will be automatically named BLKLINOO part. The user can view it after exiting the nesting dialog box.
