The following guidance helps you to ensure the best possible result from the BVBS export.

For exact instructions on the BVBS export, export settings, export file description, and the reinforcing bar length calculation in the BVBS export, see BVBS.

• Export only those reinforcement types that the production control system and machinery support.

  • Ensure that the rebar sizes, bending roll sizes, leg lengths and angles, spacings, and overhangs are within the machinery constraints.

• Model your parts and reinforcement with systematic naming and classes.

  • Create and maintain clear selection filters to exclude undesired rebar content.

• Use a file naming logic that results in unique file names, which can be traced back to the export set.

  • Export in larger sets that can be systematically traced into a specific building section or a drawing.
  • Using the default option for cast unit position will export the total amount of rebars in all relevant cast units to be combined into the same file. There might be problems with the quantities if the amount of cast units changes later on. Instead, you can use Assembly template as the File naming template, and a unique identifier to ensure that only rebars from one cast unit are within one export file.

• Keep track of the export sets in the model using part/pour UDAs.

  • After the first export, it is easy to lose track which rebars have been exported already.
  • Using rebar UDAs is heavier for the model database.
• Use private block to transfer extra information - Note that some import interfaces do not support private block.
