Does anyone know if it is possible to put a gap in an alignment using InRoads? For example, I am wanting to create a single Right-of-Way alignment throughout my project but I want a gap at intersections with other roads. It would be much easier to just have one single alignment with gaps than to have 20 different alignments.
Complex chain the right of way graphics leaving the gaps as you describe. Then select the complex chains for given side of the roadway Right of Way Left for example, and import the alignment from graphics. Be sure to use the all graphics in a single alignment option.
This is one way to create a discontinuous alignment.
Sorry for such a long delay between messages. Could you please explain how to create a complex chain. I am only familiar with create/edit alignment as the way to build chains/alignments.
The Create Complex Chain command is a MicroStation command. In the MicroStation Key-In field (Utilities> Key-In), enter Create Chain and hit Enter. Complex the graphics and follow the steps that Thomas provided (File> Import> Geometry> From Graphics).
Other options are to create the Right-of-Way as a continuous alignment with simple lines in the areas that you want to create the gaps, and use the Geometry > Horizontal Elements > Edit Element or Geometry > Horizontal Elements > Delete Element tool. Either of these will allow you to remove individual alignment elements - lines, arcs, spirals from continous or disjointed alignments.
And under Geometry > Utilitiies > Partial Delete Alignment you can also create openings in alignments after the fact. Turn on Element Snap or Point Snap and it will only delete at endpoints of elements.

It should work, though I can answer only on the basis that I'm using Geopak SS3 with OpenRoads and I'm assuming that you're using a version of InRoads that incorporates OpenRoads as well. (I have no idea about any native aspects of your software.) As you're using the tool Horizontal Geometry > Complex By Elements, simply select the elements that belong to your ROW line. Since I'm guessing the profile doesn't matter, it may be simply a matter of clicking each of the elements and then finally clicking out into space to save it. However, when it has been created and you run your mouse cursor over the ROW alignment, you may see lines showing the continuity between the segments. To avoid this, be sure that all the elements are in a chain going in one direction, though: to do this, as you're creating the ROW alignment, just click on the back end of each of the elements. From there, if you desire, you can get a ROW profile, but it will look broken as you view it if there are any gaps in the alignment. HTH.
I just realized I dredged up a thread from 6 years ago. Sorry. It came up when I searched for my own problem. This didn't address my problem, but it had similar keywords, and I didn't notice that it was 6 years old.
