Question:

I have an existing complex alignment that I need to redefine over a certain range, substituting in new horizontal geometry.  How can I do this yet preserve all rules built off the original geometry?  (i.e., other geometry, superelevation, civil cells, etc)

Answer:

The Complex Redefine command located in the Horizontal Geometry tools will accomplish this.

Notes:

• The command allows an existing complex alignment to be partially redefined over a range, substituting in a new horizontal geometry.
• The command reserves the original feature name, allowing all rules built off the original geometry to update.
• The command affects all rules relating to the alignment (Other geometry, superelevation, corridors, terrains, civil cells, etc. will reprocess to accept the revision.)
• Vertical geometry from the original alignment is preserved and carried forward to the newly formed alignment.
• Segment(s) from the original alignment that are replaced are retained in the model and are allocated a new name.
• Rules over reference files will need to be opened to initiate the update.
