INPUT UNIT(toggle on)
Metric
This option enables the user to input the Nesting setup with metric units.
English
This option enables the user to input the Nesting setup with inch units.
SETUP
In SETUP tab, the user can define the base parameters for nesting of blanks such as defining the material of the blank and input of the Edge Width, Bridge Span and Addendum size.
MATERIAL
The user can define the material of blank by two methods. One is that the user can click the button after the MATERIAL tag and the Material definition dialog box will pop up. The user may choose to create a NEW material model or IMPORT a type of material. Once a material is defined, the density is displayed in the lower boxes, and part thickness can be set. Another method is that the user can input the THICKNESS and DENSITY directly on the corresponding boxes, since these are the requisite for mass calculations.
l Thickness
This box enables the user to input the thickness of blank.
l Density
This box enables the user to input the density of part material.
PARAMETERS
In this Tab, the user will find parameters used to
control the gaps of blank nesting such as Edge Width, Bridge Span and profile
Addendum. Figure
l Edge Width
Edge Width allows user to define the gap between blank profile and strip edge.
l Bridge Span
Bridge Span allows user to define the gap between parts.
Select Blank
This option enables the user to choose between multiple blanks, and can assign different or common addendum sizes. Note that this option is only available for nesting options with more than one blank profile.
l Addendum
Addendum allows user to expand the selected profile
.

DIMENSION OPTION
LENGTH
Fix Length is used to define the total strip or sheet length.
WIDTH
Width is used to constrain the width of the strip or sheet.
l The float width used as the width constraint. The user inputs the allowable range of the blank width (Min and Max). Dynaform Nesting will calculate a series of results according to the defined float range of the width.
l Fix width used to specifically define a width for the strip or sheet.
PITCH
The Fix Pitch can constrain the pitch in nesting.
ANGLE OPTION
l The float angle used as the angle constraint. The user inputs the allowable range of the blank rotation (Min and Max). Dynaform Nesting will calculate a series of results according to the defined float range of the rotation angle.
l Fix angle used to specifically define a rotation angle for the blank.

This function enables
the user to generate the nesting result with two pair nesting blanks with
opposing orientation. The setting of Setup and Constraint in this function is
similar with that in the One-up Nesting, please refer to section
In this function
the Position option is activated after selecting the profile. This option
enables the user to adjust the relative position between the two blanks. The
user may use the three automatic tools to optimize profile orientations, or,
the user may manually select a blank profile, and the desired X- or Y-axis
translations, and/or Z-axis rotations. Click this button and the program
will open the Blank Position window as Figure
Figure
AUTO
This function enables the user to position the nesting blanks automatically through the selected optimizing scheme.
l Min. Area
The program will position the nesting blanks to minimize the surface area of the strip.
l Min. Width
The program will position the nesting blanks to minimize the width of the strip.
l Min. Length
The program will position the nesting blanks to minimize the length of progression.
MANUAL
This function enables the user to position the nesting blank manually through transforming and/or rotating.
Select Blank
This option enables the user to select the desired blank to position when there are more than one blank defined in the nesting type. The selected blank will be highlighted in the display window.
l X Step
This is the X direction increment value for transformation. If the user adjusts the position of the blank through the Manual method for transformation, the blank will move along the X direction an incremental value for each click of the transformation button. If using the Auto method, the program will calculate a series of results according to the step along the X direction. The default X step is 10.
l Y Step
This is the Y direction increment value for transformation. If the user adjusts the position of the blank through the Manual method for transformation, the blank will move along the Y direction an incremental value for each click of the transformation button. If using the Auto method, the program will calculate a series of results according to the step along the Y direction. The default Y step is 10.
l Angle
This is the angle increment value for rotation. If the user adjusts the position of the blank through Manual method for rotation, the blank will rotate by the incremental angle for each click of the rotation button. If using the Auto method, the program will calculate a series of results according the angle. The default angle step is 1.0 degree.
l TRANSFORMATION

l Rotation
Rotate the selected blank outline clockwise by incremental angle
Rotate the selected blank outline
anti-clockwise by incremental angle
Auto Position--Enables the user to get the automatically positioned result.
Apply--The program will accept the positioning result and exit the position dialog box.
This function
enables the user to generate the nesting result with mirror the original blank.
The mirrored blank is eudipleural (bilaterally symmetric) with the original
blank. The setting of Setup and Constraint in this function is similar with
that in the Two-Pair Nesting. Please refer to section
This function
enables the user to generate the nesting result with two up nesting blanks with
common orientation. The setting of Setup and Constraint in this function is
similar with that in the Two-Pair Nesting. Please refer to section
This function enables the user to
generate the nesting result with more than one different blank outline. During
the defining the Blank Outline, after selecting each blank outline the user
should click the OK button to accept each profile selection and then continue
in the same manner. When all the blank outlines are selected, the user can
click the OK button a final time to exit the line selection dialog box. The
setting of Setup and Constraint in this function is similar with that in the
