It would be very useful to have a MASTER rule (constrain or restrain) for rebars: at LEAST one rebar side or rebar leg to be positioned inside the host. Meaning we should "bind" or "link" hosted rebars to the host, so it cannot be moved far away from the host.
And yes, i know that such option will make rebar copying impossible between levels. Therefore, a new option for rebar shall be useful : "Copy rebars with/without rehosting" check box.
