Hello David,
You camn modify properties of manual reinforcement section in diaog of properties of the drawing - select "properties" from context menu of the section drawing in the pilot. Ther, in the second tab "display parameters" you can see a scheme ofall your views on the drawing, just click on the one you need to modify and make your changes. Remark: If you want to delete the section, you ned to use the dedicated function "delete reinforcement section" (grtcrebardeleteview), not just simple delete key.
If you hide the distribution on the drawing, you can display it again by selecting the definition bar and from its context menu select option "display hidden reinforcement".
Regards,
Marian
