TTSD-17597 Numbering

If assembly numbering seriesset of identifiers defined by the user, based on which Tekla Structures compares parts, assemblies, cast units, or reinforcement with each other during the numbering and gives position numbers

Numbering series is defined by a prefix and a start number.

The user can, for example, allocate separate numbering series to different phases or part types.

The property pane can be used to show and modify the properties of model objects.

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

in the part properties.

TTSD-14900 Numbering

Previously, starting from Tekla Structures 21.1, the number of an unmodified part might change if another part became exactly the same in terms of 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.

. In numbering, the unmodified part received the same number as the modified part.
Now, if both the modified part and the unmodified part have or do not have drawings, the unmodified part will keep its number. If one of the part has a drawing and the other one does not, the number of the part that has a drawing will stay the same, and the number of the part that does not have a drawing will change.

TTSD-12296 Numbering

Starting from Tekla Structures 21.0, the Compare: Welds option in 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.

The property pane can be used to show and modify the properties of model objects.

, the property pane changed the profile dimensions to some unknown numeric values.  This issue concerned both imperial units and metric decimal units, and could happen in any environment using them. This issue has now been fixed. For more details, see Parametric profiles incorrect when modified in property pane.
