The Partial Shape tool creates a dimensioned sketch (Revit detail family) of a rebar- or fabric shape and places it together with a tag in the view exactly like the Shape Detail. This command was build for easier generation of the Partial Sets representation.
Before starting make sure that in Details Tab from Settings Dialog you have chose the desired label for this kind of representation.
Activate the view where you want to place shape details.
Do one of the following:
Select a rebar or fabric (or the tag) to create a shape detail Click Reinforcement tab Tag and Detail panel (Partial Shape).
Click Reinforcement tab Tag and Detail panel (Partial Shape) Select a rebar or fabric (or the tag) to create a shape detail.
Click to place the Partial Shape Detail (SHIFT activates Ortho-Mode).
Use the Ortho-Mode to place the detail orthogonally aligned to the selected rebar. Otherwise the insertion point will be at the lower left corner of the shape detail.
Continue placing more partial shape details, or press Esc to exit the tool.
For straight bars you can show symbolic length by activating / deactivating the checkbox for “Show Symbolic Length” parameter in properties window.
