RE: SUDA Modeling of existing utilities

Hey Chris:

After extract graphics, open the profile as you have done. Now create a new profile line from beginning to ending using your known elevations. Then select the new line and Set as Active Profile on the context toolbox. This will replace the extracted profile with the new profile which is a straight line.

Regarding utility line profiles:

As you have found, Extract Graphics is usually the first step. This gets a model in place with a "default" profile. There are other methods to get started but they are more cumbersome for pressure lines and cables/conduits, in my opinion. For example, for gravity lines and drainage, I would start with place two nodes then a conduit between them.
You can design any profile you need after extraction.
- A completely new profile like above
- Replace a portion of the extracted profile. This would consist of: Partial Delete > Profile in the gap > Create Complex to stich everything back together
- Use any command in the Vertical Geometry stack.
Utility Feature Definitions have a property called "Single Gradient" which plays a factor in profiles
- Drainage and Gravity Sewer types are assumed by ORD to be True, which means that the profile cannot have any breaks. It must be a straight line. This is a short sighted assumption IMO.
- For other types, you can define this property to be true or false.
- False means that the profile can be anything. This is the normal case for pressure lines.
