Surfaces of the last

This is the first page of the Last Identification Wizard. Use this page to select the surfaces of the last to be used by the wizard.

Flattening mean

It is possible to take the average (mean) of each of the following elements of the flattened halves of the last (both inside and outside):

Heel curve

Flattening

Use this dialog to specify the options for flattening an unflattened last.

kp16

  1. Select one of the following as the Last type:
    • Normal.
    • Boot.
  2. Use the slider to specify the Average piece thickness.The corresponding value is displayed. Alternatively, enter a value; the slider is adjusted to reflect the value you entered.

Flattening is created by offsetting the surface of the side of the last by this margin.

  1. In the Flatten section, select one of the following:
    • Each half separately
    • Merge two halves at toe

Each half separately places the inner and outer halves separately, using the selected symmetry option. Select Rotate halves and Make both halves same as as appropriate.

  • Rotate halves to maintain heel height places the outer/inner last halves separately by maintaining heel height
  • Make both halves same as controls the shape of the two halves of the flattening. Specify the control by selecting one of the following:

Inside uses-flattening of the side surface for both sides.

Outside uses outside flattening of the side surface for both sides.

Average uses an average of both sides.

Merge two halves at toe merges the two sides at the toe. This will make the centre-line straight between the vamp point and the toe point, merging the two halves at a common toe point.

kp17

  1. Specify the direction the toe is pointing after flattening using Position toe to:

Right positions the toe so that it is pointing towards the right after flattening.

Left positions the toe so that it is pointing towards the left after flattening.

  1. Position inner shell lets you specify the position of the inner shell after flattening:

Above positions the inner shell above the centre-line after flattening.

Below positions the inner shell below the centre-line after flattening.

  1. Select the required Parameter file from the list.kp18

The parameter files contains the parameters to be used to create flattening. If no selection is made, flattening is controlled by the parameters that are stored in the Default parameter file that is stored in:

…..\ShoeMakerXXXXX\file\shoe\flattening\

It is possible to change these parameters, but making a change will affect the flattening process for every last you create.

  1. Click OK to save the changes and flatten the last.

When you flatten an offset concept last, the flattening that is displayed will be of the confirmed size that is useful for pattern engineering.

When you sketch lines in 3D on the offset last, they will be automatically mapped to the confirmed last and flattened accordingly.

 

User-defined flattening

Editing the flattened outlines does not just change the curve but alters the flattening mapping (that is the whole area enclosed by the curve).

  1. Clicknp3(Mean flattening flyout) to display theUser-defined Flattening dialog.np4
  2. Use one of the following methods to define the flattening:
    • Select Inner or Outer depending on the shell that you want to edit or replace. The flattening outline that is selected automatically relects the option you selected. If necessary, select a different outline. Drag points on the shell to a new position.
    • Replace with selection as follows:np5

 

Curves on the last (unified lasts

For unified lasts, an addititional option is included on the second page of the Last Identification Wizard:

kp1

Use to move the feather curve up and down. This helps to create the correct feather line when the feather edge is not sharp.

Curves on a last (STL file only)

This page is displayed if you are using a last in .stl format.

kp2

Select the top curve Top curve

kp3

  1. Click one of the following buttons:

Back displays the Surfaces of the last page.

Next displays the Points on the last page.

Finish creates the last.

Cancel finishes the Last Identification Wizard without making any changes.

  1. Select the top curve Top curve.fr1 fr2 fr3 fr4
  2. Curves on a last (STL file only)

Points on the last

Use the third page of the Last Identification Wizard to select the points on the last. The graphic on the wizard will help you identify the correct point on your model.

  1. Select the following points on the last:
    • Inner girth point
    • Outer girth point
    • Centre girth point
    • Toe point
    • Cone point.
    • Vamp point
    • Heal top point.
    • Heel bottom point.
  2. Click User Defined Points to create additional points on the last. The User Defined Points dialog is displayed.
  3. Click one of the following buttons:
