Getting started designing a shoe last

To start designing a last based on a 3D scan we start by following these steps:

• Click on step 1: Start
• Choose what you would like to create. We chose:
  • New Last
  • Left
  • High
  • Check beginners mode

The software will ask if you see the bottom side of the foot and will then ask for 5 points and what heel lift should be used:

• Metatarsal 1
• Metatarsal 5
• Center of the heel
• Fill in the heel lift
• Medial ankle
• Lateral ankle

This will start with left and followed up by the right side.

In the first dialog it is possible to reposition the markers, if not positioned correct:

• Click on the marker next to the color of the concerned position
• The screen will rotate to the corresponding view
• Click on the new position for the marker

To go to the next step click "Next".

In this dialog the foot can be rotated from the top, rear and side view:

• Click on the slider for the view that needs to be checked
• The screen will rotate to the corresponding view
• Drag the slider to the left or right to rotate the foot scan

The foot will only be rotated. In the next step the leg angle can be corrected. After rotating it is possible the heel lift is not correct anymore and can be set again by:

• Clicking on "Edit" next to heel lift
• Fill in the correct heel lift

When positioned correctly press "Next" to go to the next step.

Note that the heel and toe lift will be calculated from 0. As a reference the red Axis line from the side views is 0.

These sliders will NOT rotate the foot scan, but will make an adjustment to the angle of the leg.

• Click on the slider for the view that needs to be checked
• The screen will rotate to the corresponding view
• Drag the slider to the left or right to correct the angle of the foot

If no corrections need to be made simply press "Next" to skip this step.

Our next step is to choose a template model that we want to use as a basis.

• Select a template model
• Click on "Next"
• The software will automatically adjust the template model to the shape of the foot scan.

By clicking the - and + buttons it is possible to increase/decrease the length or width of the toe model. This can also be accomplished by using the BoundingBox.

With the 2 checkboxes you can enable/disable the sharp edge and if the software needs to make the transition between the foot scan and the template model or not.

This is also the step to check your model and "push" the parts inside you do not want to use, because if "Next" is pressed the software will merge these parts together. Clarification: the brown part is the template model and the nude color is the foot scan.

The 2 models are now merged and the basis of the last has been made.

• Transition between the 2 parts can be smoothed with our smooth tool
• Last height can be determined
• Circumferences can be checked
• Corrections can be made

For these actions please visit the corresponding tutorial page.

Now the lasts are ready to be exported for milling. By pressing the last step "Export" the lasts will be exported in separate files. By default they will be exported as STL files, but in the settings this can be changed to other formats.
