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.
