Purpose and description

Use Combine into polybeam component to create a polybeampart of a certain shape that is created as a continuous chain of beams passing through points that the user picks

The segments of the polybeam are straight, but segment intersections can be curved. For example, a beam that follows a zigzag line is a polybeam.

that follows a complex pattern.

System requirements

Tekla Structures version: Not version specific
Environments:   All

Installing Combine into polybeam

To install the extension:

  1. Download the Polybeam tools installer package from Tekla Warehouse. For more information see Downloading an application from Tekla Warehouse.
  2. Install the file package.

Using Combine into polybeam

To use the application:

  1. Open a Tekla model.
  2. Click the Applications & components button  in the side pane to open the Applications & components cataloguser interface for displaying or modifying information in categorized lists

    For example, profile catalog and shape catalog are catalogs.

    .
  3. Search for Combine into polybeam and then double-click to open it.
  4. The Combine into polybeam dialog window will open.


  1. Make desired modifications and then press the Create  button.
  2. Select the beams that you want to combine.


  1. Click the middle mouse button and the combined polybeam is created.


Note: The polybeam will be created with the same properties as the first selected beam.
The application will not color the beams - this is only to difference them in the example.

Application properties

Field Description Default
Remove consecutive collinear points: Define whether or not to remove the consecutive collinear points.
The options are:
  • Yes
  • No
Yes
Combine types Define the combine type to use for creating the polybeam.
The options are:
  • Nearest - will join the closest two end points of the selected beams.


  • Extend - will extent the beams until they meet. 



These options will be taken into consideration if none of the options mentioned in Default combine rules can't be applied.

Nearest
Search Curves Define whether or not to search for curves.
The options are:
  • Yes
  • No

Note: Please see example in Default combine rules\Input points on circle paragraph.

No
Chamfer types Define the chamfer type.
The options are:
  • None - 
  • Line - 
  • Arc - 
  • Cope - 
  • Arc point - 
  • Square - 
  • Square parallel - 
  • Line and Arc - 
No
X: Define the horizontal dimension of the chamfer.
This field isn't active if one of the None or Arc point options is selected in the Chamfer types list.
0 mm
Y: Define the vertical dimension of the chamfer.
This field isn't active if one of the NoneArc, Cope or Arc point options is selected in the Chamfer types list.
0 mm

Default combine rules

  1. Common extreme point

    If two beams have a common extreme point, the polybeam will start with opposite point to the common point of the n beam and then will go to the common point and then to the opposite point of the n+1 beam.

  1. Input points on circle

    If the end points of the selected beams are on a circle, then the combined polybeam will be build having the arc point chamfer automatically set on the middle point of the input points of the resulted polybeam. All other input points except the ends input points will be automatically removed.

Note: Search Curves option is set to Yes.
This rule requires a minimum of 4 points on the circle.
  1. Beams touching

    If two beams are intersecting the polybeam will go from the start point of the n beam to the intersection and from the intersection to the end point of the n+1 beam.
      

  1. Collinear

    If two beams are collinear, then the polybeam will be build by joining the furthest two end points of the selected beams.

  2. Ends

    If beams are parallel or in different planes then the ends rule will be used, for this rule, the polybeam will be created as following: from the first selected beam - the points will be taken from the start to the end and from the second selected beam - the points will be taken from the start to the end, in their creation order.
