Example 2: Stretch Beams to Columns

To illustrate this adjuster type, let’s use a common steel structure composed of Columns, Beams and diagonal bracing:

We see that the Beams’ 1D Members are not connected to the Columns: There is no continuity, which is necessary for structural analysis.

The solution is to generate a rule that stretches Beam axes to the Columns.

  • Members Group 1: Beam
  • Members Group 2: Column
  • Method: one to the other (stretch the Beam to the Column, but leave the Column as is.)
  • Adjuster type: Stretch
  • Additional options for stretch: the maximum stretch allowed.
    Note: The defined tolerances are length-type values: The units specified for Length in Preferences > Working Units apply.

The Beams now meet the Columns, but the bracing is still not right.
