Note: This button is only available when Reinforce with 3D model is not active. If you are working in Reinforce with 3D model mode, number off management is automatic. In this case, this parameter does not need to be modified by the user.
When the button is set to +, the number off information for meshes that have already been placed increases by one with every additional mesh that you place.
If you merely want to display a mesh that has already been placed in a different view, you can lock this counting feature temporarily.
Click + or - to block or reactivate the counting function:
+ means that the function continues counting
- means that the function stops counting (i.e. off)
