Tips for reinforcement shape recognition in Rebar shape manager
The reinforcing barreinforcement that represents a steel bar used to reinforce a concrete structure
The steel bars are usually ribbed and they are used to increase the tensile strength of concrete.
shape recognition is based on each shape’s bending shape rules. The shapes and their rules are listed in the RebarShapeRules.xml file, located in the ..\ProgramData\Tekla Structures\<version>\environments\<environment>\system folder by default. Sometimes a shape matches the rules of two shapes, and Tekla Structures does not recognize the reinforcing bar shape as expected.
The most convenient way to ensure that a shape is recognized correctly is to modify the shape definition by adding more rules to the shape in Rebar shape manager.
However, if necessary, you can manually modify the RebarShapeRules.xml file and thus affect the shape recognition. When Tekla Structures recognizes the shape, the order of the shapes in the RebarShapeRules.xml is important:
- The first shape that matches the rules is the one that Tekla Structures recognizes as the shape. If you need to change the order of the shapes to change how Tekla Structures recognizes the shape, you can do it by manually modifying the RebarShapeRules.xml file. If you modify the file and change the order of the shapes, make sure that the structure of the file stays valid.
- You can divide the shape definitions in several RebarShapeRules.xml files and different folders. Tekla Structures searches the RebarShapeRules.xml file in the model, project, firm, and system folders in that order. Tekla Structures uses the first matching shape in the first RebarShapeRules.xml file which is found based on the search order.
