**Problem:**

I am attempting to import geometry into OpenRoads using the **Import Geometry **tool. However, one of the horizontal alignments is imported but is not ruled. Why is this alignment not ruled when others are?

**Solution:**

If any of the following conditions are true, the imported geometry will not be ruled:

If the following is true, then a "too many elements" message is produced:

- Number of adjacent lines is greater than 20

If the following are true, then a "too complex message" is produced:

- First element is a spiral
- Last element is a spiral
- Back to back spirals (i.e., double spirals or reverse spirals)
- Spirals must be tangent to the previous element ( tangential differences must be less than 0.1 seconds or it is consider non-tangent)
- Spirals must be tangent to the next element (tangential differences must be less than 0.1 seconds or it is consider non-tangent)
- Single spiral between adjacent circular arcs and the circular arcs are reversing (i.e., back curve to the left and the ahead curve to the right or vice versa)
- Adjacent elements are not coincident (i.e., delta x less than 0.0001 and delta y less than 0.0001 or it is consider non-coincident)
- Elements are too short (i.e., length is less than 0.5)
- Circular arcs with a sweep angle of 180 degrees (i.e., median noses or loop ramps)
