Create a twin profile

A twin profile consists of two parallel and identical beams. You define the positions of both beams by selecting the twin profile type and setting the clearance between the beams in two directions.

On the Steel tab, click Beam > Twin profile.
Pick two points.
Tekla Structures creates the twin profile between the points you picked, using the Twin profile properties in the property pane.

Alternatively, you can start the command in the property pane.

Ensure that you have nothing selected in the model.
In the property pane, click the Object type list button and select Twin profile from the list.
Tekla Structures starts the command and shows the properties in the property pane.

Modify twin profile properties

If the property pane is not open, double-click either of the beams to open the Steel beam properties.
Change the properties as needed.
Click Modify to apply the changes.

Twin profile properties

Use the Twin profile properties in the property pane to view and modify the properties of a twin steel profile. The file name extension of a twin profile property file is *.dia.

If you have customized the property pane layout, the list of properties may be different.

Setting	Description
General
Name	User-definable name of a twin profile. Tekla Structures uses part names in reports and in Document manager , and to identify parts of the same type.
Profile	The profile of both the beams in the twin profile.
Material	Material of the beams.
Finish	Type of finish. Finish is user definable. It describes how the part surface has been treated, e.g. with anti-corrosive paint, hot galvanized, fire retardant coating, etc.
Class	Use to group twin profiles. For example, you can display parts of different classes in different colors.
Twin profile type	Define how the profiles are combined.
Numbering series
Part numbering	Part prefix and start number for the part position number.
Assembly numbering	Assembly prefix and start number the assembly position number.
Position
On plane	Twin profile's position on the work plane , relative to the twin profile's reference line.
Rotation	Rotation of the twin profile around its axis on the work plane.
At depth	Position depth of the twin profile. The position is always perpendicular to the work plane.
End offset
Dx	Change the length of the twin profile by moving the twin profile end point along the twin profile's reference line.
Clearance between members
Horizontal	The horizontal clearance between the profiles.
Vertical	The vertical clearance between the profiles.
Custom properties
More	Click the More button to open the user-defined attributes (UDAs) of the part. UDAs provide additional information about the part.
