Screw group extension

This documentation page provides an overview of the extension package for screw group types in Tekla Structures. Each screw group object type is modeled similarly to its bolt counterpart, with specific properties and parameters unique to screw objects. The package includes also specific presentation functionality for drawings for exact presentation of location and threading of the screw object. 

Screw group

 

Install the Screw group extension from the Tekla Warehouse.

 

Benefit of screw group objects are: 

  • Easy to find Dedicated tools for screws
  • Ability to customize dedicated attribute files for screws
  • Specific properties that are relevant only for screw groups
  • Ability to find all screw object types based on a filter
  • Define predrilled holes (Through) or pilot holes (Blind)

Screw Group Object

  • Modeling: Similar to a basic bolt group, 
    • Note: direct modification creation feature can't be used.
  • Properties: Defined in the property pane.

Special Screw Properties

All screw objects have the following special properties:

  1. Length
    • Shows all possible lengths of the screw based on selected size and grade
    • Property name: Length
Screw length
  1. Threaded length
    • Is used for defining thread length from the tip and from the head of the screw  
    • Property names: ThreadEnd and ThreadHead
    • Note: These properties are not visible in the model view, these are used in the drawing for showing the threading
Thread length
  1. Product code
    • Is used for defining a specific product code for ordering purposes 
    • Property name: ProductCode
  2. Hole size
    • Is used for defining an actual hole size for the screw together with Plain hole type and Hole depth properties
    • Property name: HoleSize

Custom Object Types

  • Custom Object: Screw objects are created using custom objects.
  • Type name: ScrewGroup
  • Filter: Custom objects can be used in filters by using the property name in filter:
    • __CustomObjectType

Drawing presentation

Threading of the screw is visible in the drawing by selecting “Screw presentation” from Custom presentation property in the bolt property pane

Drawing representation

User-defined attributes (UDA’s)

  • Screw objects will have the same UDA’s as bolts
