Same Element Numbers

Multiple elements with the same element number

For sortable and fixed element numbers, multiple elements can now be assigned the same number. Previously, the element number was uniquely assigned to a specific element. This must be taken into account in many places in the system:

• The same element number cannot exist for different types. If a new element number is assigned, the numbers of the other types are also taken into account. If an element number is forced, the element numbers of the other types are also adjusted if necessary.

  • Example: A fixed element number is set to E_14 already exists . A unique element number E_14 ; this is now assigned the next available number, e.g., E_15 .

  • Example: A unique element number is set to E_14 . Several elements already exist with the sortable element number E_14 ; these elements are all now assigned the next available number, e.g., E_15 .

• In DICAM, function 6-5 lists the element MOS, i.e. the element numbers for all elements.

  • Even if the element number is the same, there is an entry in the list for each element.

  • The element number is followed in parentheses by a counter and the total number of that element number. Thus, if the element SE_12 occurs five times, the entries are: SE_12 (1/5) SE_12 (2/5) SE_12 (3/5) ... The counter has no further meaning; it is assigned randomly. The preview can be used to identify the element.

• When sorting components, the element, i.e. the element number, can be taken into account.

  • If two identical components belong to different elements with the same element number, they will receive the same serial number.

  • To sort elements, their components must be sorted. Conversely, the element number can also be taken into account when sorting the components. Even in this situation (circular reasoning), the system ensures clear and factually correct numbering of the components and elements.

Impact on results for elements

• Element plans are created for each element, even if the elements have the same element number.

  • Even if the elements themselves are identical, they are located at different locations within the structure. Adjacent walls, components, or even drawing elements may be different. These are depicted on the plan, which also makes them different.

  • If the plans are stored in several steps (e.g. by floors) and only one plan is created for the same elements, the plan could be missing in the next step and the element could be overlooked.

  • As a hint, the total number of elements with this number is displayed in the text field of the element plans behind the element number.

  • Typically, the element number is used in the plan name. Since this will now be used for multiple plans, a counter should definitely be used, otherwise the question of overwriting will repeatedly arise.

  • The building element list should be used as an overview of the elements. It shows their distribution across building elements (walls, ceilings, roof surfaces) and floors.

• In the building element list, identical element numbers within a building element (wall, ceiling, roof area) are grouped together. For example, if there are three identical elements in a ceiling, only one row with the number 3 is created. Identical elements in different ceilings receive their own rows, as they are divided according to building element.
