Split parts

Use splitting to split a part into two. You can use splitting with straight parts, polybeams and curved beams without offsets, and normal and tapered reinforcing bar groups. You can also split contour plates and concrete slabs.

When you split parts, Tekla Structures retains the properties and attached objects when the parts are split.

Limitations:

  • You cannot split surface treatment.
  • You cannot split bent plates, lofted plates, or lofted slabs.
  • If the part to be split contains a bolt group, and the part is split at a position where there are bolts, you need to also split the bolt group.
  • If you have already carried out numbering, the part and assembly number is assigned to the part that was at the original start point. The other part gets a new number.

Split a straight or curved part or polybeam

  1. On the Edit tab, click Split.
  2. Select the part you want to split.
  3. Pick a point for the splitting line.
  4. If you split a polybeam, check that the following are correct:
    • The position and orientation settings of the split polybeams
    • The components related to the split polybeams

    New part start and end points are placed at the position of the split.

Split a plate or slab

  1. On the Edit tab, click Split.
  2. Select the contour plate or concrete slab you want to split.

    Note that bent plates, lofted plates, or lofted slabs cannot be split.

  3. Pick the points you want the splitting line to go through.

    The first picked point and the last picked point need to be on an edge of the plate or slab.

    New part start and end points are placed at the position of the split.

Note:

Areas with chamfers, cuts, or openings cannot be split. If you try to pick points in these areas, the preview of the splitting line turns red, indicating that splitting is not possible.
