Use the warning symbols to verify whether the alignment design meets the specified criteria and design checks, or if the alignment elements are tangent to each other.
When an alignment uses the criteria-based design feature, the alignment geometry must meet the design criteria specified in the design criteria file and design checks.
You can also specify that Autodesk Civil 3D checks that each line, curve, and transition element is tangent and connected to adjacent elements.
When an alignment sub-element either violates the design criteria, or is not tangent to an adjacent element, a warning symbol is displayed in the following locations:
- The drawing window — The
warning symbol is displayed on each sub-element that violates the design. Note: The size of the warning symbol does not adjust automatically. After zooming in or out, enter REGEN to resize the warning symbols. - The Alignment Elements vista — The
warning symbol is displayed in the No. column of the sub-element that violates the design. If a criteria in the design criteria file was violated, the warning symbol is also displayed next to the specific criteria and parameter value that violates the design criteria. - The Alignment Layout Parameters dialog box — If a criteria in the design criteria file was violated, the warning symbol is displayed in the Design Criteria panel next to the Property that was violated, and in the Layout Parameters panel next to the Parameter that was violated. If a design check was violated, the warning symbol is displayed in the Design Checks panel next to the design check that was violated. If tangency is violated, the warning symbol is displayed in the Layout Parameters panel next to the General Number row.
You can use the warning symbols in the drawing window to view information about design violations. When the cursor is hovered over a warning symbol in the drawing window, a tooltip displays information about the violation. If a design criteria was violated, the tooltip displays the criteria that was violated, as well as the minimum value required to meet the criteria. If a design check was violated, the tooltip displays the name of the design check that was violated. If tangency was violated, the tooltip indicates which element (previous or next) is not tangent with the current entity.
The name of the design check should be similar to the formula you enter in the Design Check field. When a design check is violated, only the design check name is displayed, and not the minimum acceptable value. If the formula is in the design check name, it is easier to correct the violation.
