Casting direction

Casting direction

To indicate the casting direction of a concrete part, you can define which part face you want to face upwards in the casting form. The top-in-form face is displayed in the front viewdefault view that is created using the part’s or component’s coordinate system and that shows the part or component from the front direction

Part’s front view is a view on part plane created of the part’s front plane.

of a drawing.

To enable this featurepart of Tekla Structures functionality that is maintained and owned by Trimble Solutions and that is included in the Tekla Structures installation

for non-concrete parts as well, and to indicate in the model the part face that is shown in the drawing main (front) view, use the advanced option XS_SET_​FIXEDMAINVIEW​_UDA_TO_​AFFECT_​NUMBERING.

The casting direction affects the numberingprocess of assigning position numbers to parts, cast units, assemblies, or reinforcement

In Tekla Structures, the position numbers assigned in the numbering are shown in marks and templates, for example.

of parts. If you define the casting direction for parts that differ only by their modeling direction, they get different position numbers. This is because the modeling direction affects the top-in-form face of the parts. By default, the casting direction of the parts is undefined, which means the modeling direction does not affect numbering.


In drawings, use the Fixed coordinate system to show the top-in-form face in the front view.


In the following example, each cast unit gets a different position numberidentifier that is assigned to all similar parts, assemblies, cast units, or reinforcement

Position number consists of a prefix, separator, and running number. The prefix is part of the position number, identifying a numbering series. The running number is part of the position number, and is the assigned number in the numbering series, based on the start number. The separator is an optional character, such as a slash, that separates the prefix and the running number.

In Tekla Structures, the position numbers assigned in the numbering are shown in marks and templates, for example.

In the US, the term piece mark or ship mark is used to refer to a position number.

, because the top-in-form setting and the orientation of the panels is different. The red arrow indicates the modeling direction.

In the following example, the cast units get the same position number, because their top-in-form setting has not been defined. The red arrow indicates the modeling direction.
