Continuous concrete structures cannot be selected or highlighted in part views. When you hold the mouse pointer over a concrete structure in a part view, Tekla Structures highlights the original parts belonging to it. You can select a part and modify it if needed:
Duplicates and overlapping parts are counted only once in the volume calculations for pour objects. Note that single part and cast-unit volumes are still calculated the same way as before, which means that the sum of single part and cast-unit volumes may be higher than the volume of pour objects that are defined from exactly the same part geometry.
When you reinforce a concrete structure, you need to reinforce the individual concrete parts within it in part views, or you can reinforce pour objects by using Reinforcing Bar Shape Catalog or rebar sets in pour views. Therefore, you can reinforce a part of a continuous concrete structure independently from the whole continuous concrete structure. All reinforcement are visible both in part views and in pour views.
