The options are:

  • Offset

    Fixed distance.

  • % x t

    Percentage of the plate thickness.

Four cuts

Manual creation of reducing piece

You can create the reducing piece without existing profiles by picking three points at each end of the reducing piece. The picked points define the size of the reducing piece. You can define the shape of the manually created reducing piece on the Parameters tab.

Option

Description

Picking order of the points:

  • center point

  • horizontal distance

  • vertical distance

Parts tab

Use the Parts tab to define the thickness of the triangular plates in the reducing piece and the reducing piece position.
