You can create rebar images with real values of rebar segments and then add them to the Schedules.

There are a few commands related to this:

Check Rebar Image Configuration before creating Rebar Images: these are the settings used in the above example. Choose a text style and size that will meet your standards.

After settings are done, you can go ahead and:

Create Rebar Images - this will create rebar images for all reinforcement in the project

Rebar Images for Selected - will be applied only on selected rebar

Rebar Images by Host - select Host so that images will be created only for its rebar

Any of these commands will create a .png image file and assign it to the Instance Image parameter of the rebar. You can use this parameter in the schedules to show them on the sheets.

Name of the image (as seen in screenshot above):

AGACAD - created by our software

Solid Walls - the name of Rebar Partition

18 - Rebar Number.

These commands can be used at any time in the project. But if you want to create Rebar Images while you Create Assemblies, check this option in Shop Drawing Configurations:
