Situation

Description

Connection between two beams.

Profile limitations

You can create three different notch types:

  • Free
  • Heerema
  • HSM

When creating a Free notch type, the main and the secondary beam do not always have to have the same size. You can set them up according to your needs and create the connection.

When creating Heerema and HSM notch types, the beam size depends on the selected Heerema and HSM settings.

For all Free and Heerema types, and most HSM types, skewed secondary beams are allowed. Sloped secondary beams are only supported by some specific HSM types. See the table below for examples.

Notch type Example
Free

HSM

Selection order

  1. Select the main part (beam).

  2. Select the secondary part (beam).

    The connection is created automatically when the secondary part is selected.
