Combine into polybeam

Purpose and description

Use Combine into polybeam component to create 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 
   Image

   
   in the side pane to open the Applications & components catalog.
3. Search for Combine into polybeam
   Image

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

Image

5. Make desired modifications and then press the Create 
   Image

   
   button.
6. Select the beams that you want to combine.

Image

7. 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. Image   Image Extend - will extent the beams until they meet.  Image   Image 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 -  Image Line -  Image Arc -  Image Cope -  Image Arc point -  Image Square -  Image Square parallel -  Image Line and Arc -  Image	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 None, Arc, 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.

2. 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.

3. 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.

4. Collinear

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

5. 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.
