  1. Mid-ContinentMicroStation Community2008 Conference Athens Civil Platform Coordinate Geometry Tools Robert Garrett, Technical Product Manager Bentley Systems Inc Opening Demo .

  2. What is Civil Platform ? Civil Platform is Bentley’s next generation civil initiative. It incorporates advanced interface concepts, more powerful tools and uses associative, rules-based methods to preserve design intent.

  3. Civil Platform Geometry Coordinate Geometry will be the first released portion of the Civil Platform. The first release will provide a full suite of horizontal geometry tools. Profile and cross-section tools will be added in post Athens releases.

  4. FUNDAMENTAL QUESTION: What is geometry?

  5. What is Geometry? Alignments? Yes. BUT…what about the other 99% of your project?

  6. What is Geometry? Alignments. Edge of Pavement. Edge of Parking. Turn Lanes. Tapers. Median Noses. Gore Areas. Pipe centerlines. Drainage Nodes. Trees. Utility Nodes Utility Lines. Building Footprints. Subdivision Layout Lines Setback Lines. Property Lines. Right-of-Lines. Surveyed Points of all kinds. And on and on and on.

  7. What is Geometry? As civil designers, geometry is everything we do. Every line we draw and every calculation we make is coordinate geometry. EVERYTHING!

  8. ALL of this is Geometry.

  9. And for site designers, so is ALL of this.

  10. Attributes of Geometric Elements Geometry is all kinds of elements that we calculate. Geometric elements do not stand alone, they are related to each other. These relationships are often cumulative. One builds on another. The interrelationships are sometimes complex. We have gotten so accustomed to the relationships that we hardly even notice many of them. If one of the calculations changes then a whole series of recalculations are required to update the project.

  11. Historic Approach Historically, we have used cogo for alignment computations, then used generic CAD tools for most of the other 99%. The capabilities of non-alignment cogo tools varied between packages The result is a dumb graphic with no relationship to the remainder of the project. What is needed is a toolset that works like the generic CAD tools but results in intelligent elements.

  12. How Civil Platform Geometry Works Provides a suite of next generation tools to perform the required calculations. Provides an improved user interface providing heads-up prompting and feedback. Calculations are rules based. Preserves design intent - The relationships and calculation input is preserved not just the result. Even snaps and Accudraw input are preserved As a result, related geometric elements can provide a cascade of updated calculations when a single change is made.

  13. Heads Up Interface Prompts and feedback are presented at the cursor. No need to divert your attention to a dialog. On screen editing and manipulation. Customizable dialogs even to the point of no dialog being required.

  14. Demo Heads Up Interface and Customizable Tools

  15. Rules Based Calculations Instead of just a dumb graphic, the geometric elements are created by rules, which by definition also provides the ability to edit the rule as needed. It also is the first step in preserving the design intent.

  16. Preserve Design Intent If you computed a curve with a tangent snap, there must have been a reason right? If you set a drainage node 100 feet from the corner of a building on the centerline of a ditch, there was most certainly a reason. Even an onscreen DP may have significance to you, the designer. Civil Platform Geometry preserves this input which allows future editing, and in a sense, helps preserve your thought processes.

  17. Demo Rules, persisted data, properties and manipulators. Even snaps are preserved

  18. Relationships Not only is the design intent for individual elements preserved but the relationships between elements are also preserved. For example: All edges of pavement are laid out based on a relationship to a centerline (or baseline) using offsets, stationing and perhaps tapers. Preserving these relationships updates the edges if the centerline changes, saving you work.
