Why are the dimensions of the mouldings on the right and left different?

Error description

Although the same moulding was chosen for both sides, the dimensions for the moulding on the two sides are different.

Causes of errors

There are two possibilities why the dimensions are different.

  • The bale size on the sides was set differently
  • The measurements of the two sides differ in length

Troubleshooting

GP OptiCAD calculates the size of the selected last based on the ball of the foot and the length of the measured foot. Depending on their value, the selected last is stretched or compressed accordingly. For this reason, the length specifications may differ. The decisive factor is that the last encloses the measured foot well. Different lengths of last are not an error in this case.
