Define if a profile is treated as straight or bent.

Define the maximum bending amplitude per meter in the body and thickness directions to determine whether a profile should be treated as straight or bent. These values can be set to depend on the profile type, material type, and the profile maximum length. The values are defined in the Conditions table.

Define the following properties in the table:

  • Profile type – Set the profile type. This can be a short name or the full name. Valid names are for example HP, HP200, and HP200x10.
  • Material – Set the material type. An asterisk (*) or a blank sets all material types are valid.
  • Max. length – Define the maximum profile length. Only profiles with a length up to the maximum length are handled. Define the short profiles before the long ones.
  • Bending body –Specify the bending amplitude per meter in the normalized body direction, over a length of 1000 mm.
  • Bending thickn – Specify the bending amplitude per meter in the normalized thickness direction, over a length of 1000 mm.

The system checks each profile defined in the Conditions table from top to down. If the length of the profile is smaller or equal than Max. length, and the Material and Profile type are the same as defined, then the defined bending amplitude values are used to check if the profile is treated as straight or bent.

Amplitude is calculated either on the outside or the inside of the shell.

  • Outside (default) – The system takes into account all contour points wider than 0.5 mm, enlarges the two related vectors by 0.5 meter, and then calculates the amplitude.

  • Inside – The system takes into account all contour points over the length of 0.5 and 1.0 meter, and calculates the real amplitude.

To use the Inside method for amplitude calculation, add manually the amplitude method environment variable in the settings.cmd file in the active norms. The following activates the inside amplitude calculation method:

environment AMPLITUDE_METHOD='new'
