The Edit Mark tool selects all instances of a rebar or fabric sheet mark to edit the properties (such as diameter, hooks, rebar shape, etc.) consistently. Its operation will differ depending on the selected mode of operation, whether the command affects a single sheet, host or the entire project.
Do one of the following:
Select a reinforcement instance or its tag of the mark to edit Click Reinforcement tab Mark panel (Edit).
Click Reinforcement tab Mark panel (Edit) Select a reinforcement instance or its tag of the mark to edit.
Edit the properties of your wish.
You can select the reinforcement itself or its tag.
The properties of a rebar or fabric sheet mark as part of a reinforcement system (such as Area or Path Reinforcement) can’t be changed. In this case you have to remove the reinforcement system first.
