Change the default rebar constraint references and offsets in multiple views.
This video demonstrates the following:
You can place standard rebar shapes that snap to adjacent standard rebar, or you can constrain them to host faces to meet the specific needs of alignment and offsets within a host.
In this reinforced column we'll place adjacent rebar and copy them to another position within the column. First we'll place one length of a standard rebar shape in the column. When you place the second rebar instance, use the Constrained Placement to the previously placed rebar element. Stirrup and tie rebar cannot be constrained on placement. The rebar elements are attached. Moving the constraining bar will move the constrained bar. However, the constrained bar will separate when moved from the constraining bar. Resizing the constrained bar will also reposition the constraining bar to accommodate its new geometry and maintain its attachment. The constrained behavior will be transferred to copied rebar elements.
You can also edit the constraints that rebar associates with its host and cover. In this elevation view of the column and footing, you can adjust and override specific distances of a selected rebar element from constraint planes in the host. Select the Edit Constraints tool to open the constraint editing mode. The main segment of the rebar is highlighted in orange. The reference line or plane is also highlighted in orange to identify the relationship. You can also select and restrain other segments of the same bar. Click a different parallel reference line to assign a new constraint reference. Notice the dimensions reported have also changed. You can also use the checkbox near the rebar offset dimension to quickly select the host cover. Deselect it to select the host surface. Click the dimension to enter a specific distance and press Enter to apply. Click Finish to apply the constraint changes and exit the editor. Make similar adjustments in different views when necessary.
The graphical constraints manager allows for precise rebar placement. You can place standard rebar shapes that snap to adjacent standard rebar, or you can constrain them to host faces to improve reinforcement workflows.
