Free Form Rebar Aligned Distribution

Free form rebar aligned distribution populates the surfaces of irregularly shaped hosts with variable planar distribution.

Use free form rebar to create rebar sets with planar bars distributed along the faces of a structural element and aligned to a distribution path. Like the surface distribution, you can model in 3D views and select the structural element faces to which the bars are aligned.

The bars in an aligned distribution are created at the intersection of each individual bar plane with the host surface . All the bars are planar, respect the cover of the host and are aligned to the distribution path, by default.

The path is the edge of an element that can host rebar. You can directly select the path when you place the rebar set. You click on structural element edges during set placement to select the path. You can edit the path by adding or removing faces from the Path Surface 1 and Path Surface 2 constraints, in edit constraints mode.

Rebar cover

The bars in a free form rebar set with an aligned distribution are created at the cover offset from the intersection of the selected faces. When multiple faces define the host surface, the cover of each face is used to generate the individual bar segments.

When you specify the Style property of free form rebar to Stirrup/Tie, you can change the Stirrup/Tie Attachment For the Stirrup/Tie value of the Style parameter, the free form bar can be attached to either the inside or the outside of the concrete cover, depending on the setting of the Stirrup/Tie Attachment parameter.

You can choose how to align the bars in the set and also make the bars in the set be parallel to the planar face selected in the Align / Close constraint:

Alined to Path	Parallel to Face

Perpendicular to Face	Vertical

Tip: Place vertical bars in a round column. You define a rebar set in a round column by selecting the outside faces for the host surface and the circular edge for the distribution path.
