AutoConnection and AutoDefaults rules

AutoConnection and AutoDefaults rules

You can create your own AutoConnectiontool that creates connections with predefined properties in certain framing conditions

and AutoDefaultspredefined properties that AutoConnection uses when creating connections

rules for project and company defaults. By defining rules you can accurately select connections and connection properties when using AutoConnection and AutoDefaults.

General rules

  • Profile name is the name in the profile catalogcatalog that displays profiles and information on the profiles

    In addition to the available profiles in the respective Tekla Structures environment, the user can add fixed or parametric user-defined profiles to the profile catalog. It is also possible to import profiles to the profile catalog.

  • Number of secondary parts
  • Number of main parts
  • Material name

Orientation rules

Depending on the relative angle of a beam, the connections can be classified as sloped, skewed, or cant. The angle value can be between - 90 and 90 degrees.

  • Sloped angle (relative to main part(1) part that exists in a building object and that determines the position number for the assembly or cast unit and the direction of assembly or cast unit drawings

    (1) Main part can be an assembly main part or a cast unit main part.

    (2) input part that the user selects first when creating a component

    (2) Connections and details always have a component main part.

    cross sectiongeometrical form of a part sectioned perpendicular to its axis

    )

    The longitudinal axis of the secondary part(1) part that exists in a building object and that is connected to the main part

    (1) Secondary part can be an assembly secondary part or a cast unit secondary part.

    (2) input part that the user selects after selecting the component main part when creating a component

    (2) A component can have none, one or more component secondary parts.

    follows the slope of the longitudinal axis of the main part.

  • Skewed angle (relative to main part longitudinal axis)

    The longitudinal axis of the secondary part is skewed according to the main part cross section. The angle is the smaller of the angles between the longitudinal axis of the secondary part and the main part Z or Y axis.

  • Cant angle

    For rotated secondary parts

Dimension rules

  • Profile depth
  • Web depth

    For profiles with an upper and lower flange, the web depth is: h-t1-t2-2*r1

    Or, if t2 is zero: h-2*t-2*r1

    For profiles with one flange, the web depth is h-t-r1-r2.

  • Web thickness
  • Flange thickness

Forces and strengths

  • Shear force
  • Axial force
  • Bending moment
