From the Task menu, select Civil Tools > Horizontal Geometry > Start Station. Use the Start Station tool to set the alignment's Starting Station.When connecting Alignment Elements, set the Trim/Extend option to Both to ensure that the Elements meet correctly.An Undo will discard all the placed PI's and start the command over.

When using a Tentative Snap, the Reset button must be used before a Tentative Snap is used at a different location.If the curve does not display while placing the next PI, then the current curve is probably overlapping the previous curve. When using the Complex by PI command, the Horizontal Radius can be changed on the Heads-Up prompt prior to accepting the next PI.Additional assistance may be found from the Task menu, just select Civil Tools > OpenRoads Help > OpenRoads Help. Use the Horizontal Geometry Tasks to create all Alignments in the Geometry dgn.When creating a Complex Alignment by either the Complex By PI or the Complex By Elements command, select an Alignment feature definition that identifies the type of alignment being created. When creating an Alignment by Elements, we recommend selecting the Alignment Elements feature. To select a Feature Definition, click the Feature Dropdown and expand Ali n Road Design > Road options, then select the appropriate feature from the Road features.

The only place this feature override doesn't work is with Vertical Geometry. Play it safe, toggle the Use Active Feature Definition button OFF and ON once before creating new features. Be leery of false positive amber shading of this button. Similar to other OpenRoads buttons, this button changes from a White background to an Amber background when toggled ON. Therefore it is necessary to toggle the Use Active Feature Definition button to apply the override. However, selecting a Feature Definition from the Toggle Bar does not automatically make the feature active. Find it from the Task menu, select Civil Tools > General Geometry (or Horizontal Geometry) > Feature Definition Toggle Bar. The Feature Definition Toggle Bar allows the user to select a Feature Definition once and it be used until a new Feature is specified. Once in, open the drawing's Default model. For transferring MX alignments into OpenRoads, there are two separate processes depending on whether the working units of the drawings are US Survey Feet or Feet.
