Two Intersecting Alignments

345 Views, 1 Replies

How do I project the Proposed Road Level information from Road_1 at the intersection of Road_2 (Alignment_GA.jpg) onto the Start of the Profile for Road_2 (Alignment_Profile.jpg) to give me my tie in start point?

 

How do I obtain the exact chaiange of the intersection Point?

 

How can i extend Road_2 onto the horizontal curve of Road_1 so i know they exactly intersect?

 

Any help would be much appreciated

Others might have different options, but here's how I handle these situations:

Create a surface from the corridor for alignment 1. Either Query or Label the intersection point with a station/offset label that includes a reference text component for Surface Elevation. Use that elevation as the starting elevation for Alignment 2.

See above. This label will include station value. (Chainage = Station, right?)

Explode down to a polyline, use Extend to extend the polyline to Align 1, create Align 2 from the polyline.
