Create and manage construction levels

In the Construction Levels dialog box, you can define and modify the levels that you need to construct your model. The levels can be floors, roofs, or intermediate levels required to define specific items.

Open the Construction Levels dialog

Do one of the following:
  • On the Model tab, click Construction Levels.
  • In the Structure tree, double-click Levels.

Insert a single construction level

  1. In the Construction Levels dialog box, select an existing level.
  2. According to your needs, click either Insert Above or Insert Below.
  3. If necessary, change the level type:
    • If you are creating a steel structure, set each new level as T.O.S. (top of steel).
    • If you are creating either a concrete or mixed material structure, set each new level as S.S.L. (structural slab level).
  4. If necessary, change the level name.
  5. For the new level, do one of the following:
    • Specify the height above the base in the Level field.

      The inter-story spacing is calculated automatically.

    • Specify the inter-story spacing in the Spacing field.

      The level is calculated automatically.

    Note: A default height is calculated for the new level based on the spacings of any existing levels immediately above or below it. Either accept the height, or adjust it as required.
  6. If you want Tekla Structural Designer to treat the level as a floor, select the Floor option.

Insert multiple construction levels

Multiple levels can be inserted, either above the current top level, or below the current bottom level.

  1. In the Construction Levels dialog box, select an existing level.
  2. According to your needs, click New on Top or New at the Bottom
  3. For each construction level, type the level spacing and click OK.
    Tip: If you have new levels at 12' 6" , 18' 6" , 27' 6" , 36' 6" and 27" above the current level, you can specify the levels as 12' 6" , 18' 6" , 3*9'.
  4. If necessary, change the level names.
  5. If necessary, change the level type:
    • If you are creating a steel structure, set each new level as T.O.S. (top of steel).
    • If you are creating either a concrete or mixed material structure, set each new level as S.S.L. (structural slab level).

Make a level an identical copy of another level

If needed, you can determine a level as an identical copy of another level. In this case, all changes made to either the source level or the identical level are automatically applied to both levels. To make a level an identical copy of another level, see the following instructions.

  1. Open the Construction Levels dialog box.
  2. At the level you want to be a copy, click the arrow in the Source column.
  3. Select the level that you want the current level to be identical to.
  4. Click OK.

Make a level an independent copy of another level

If you determine a level as an independent copy of another level, any changes made to each level only apply to that level. To make a level an independent copy of another level, see the following instructions.

  1. Open the Construction Levels dialog box.
  2. At the level you want to be a copy, click the arrow in the Source column.
  3. Select the level that you want the current level to be identical to.
  4. Click OK.
  5. Reopen the Construction Levels dialog box.
  6. At the same level, click the arrow in the Source column again.
  7. Set the level as -unique-.
  8. Click OK.

Modify the properties of a construction level
