1 2014 Bentley Systems, Incorporated Best Practice: Corridor Modeling Presented by: Joe Waxmonsky PE, Bentley Civil

2 Bentley Systems, Incorporated Best Practice: Corridor Modeling

3 Agenda General House Keeping Object Types Template Library Scalability Demo Bentley Systems, Incorporated

4 2D VS 3D Bentley Systems, Incorporated

5 Really 2D? Bentley Systems, Incorporated

6 SUM(2D + 3D) = HOLLYWOOD BIM Bentley Systems, Incorporated

7 House Keeping Start with a MicroStation 2D DGN. Allow Civil to Create/Manage the 3D Separation of 2 Worlds but in same DGN Doesn t mean you can t use 3D Environment Think of it as Bentley Systems, Incorporated

8 Civil Objects in the Model Corridors Linear Templates Surface Templates Surfaces 3D Breaks/Strings 2D Ruled Geometry & Profiles Remember Civil Cell is any combination of the above Bentley Systems, Incorporated

9 Corridors Multiple Template Drops Uses Super Based off Template Drop Interval Station Lock/Even Station Bentley Systems, Incorporated

10 Linear Templates Single Drop with frequency of drop based off Stroking of Element hung upon Use of Site based entities where accuracy > scale Bentley Systems, Incorporated

11 Linear Templates Delta from Corridor No Super No End Condition Exceptions No Secondary Alignment No Key Stations No Curve Widening Design Stage has no Template Management or Critical Sections Bentley Systems, Incorporated

12 Surface Templates Apply a Template to a Terrain Model Reads template points & components at Origin More than Intersections! Bentley Systems, Incorporated

13 Corridor Modeling in Review Corridor Resides in the DGN 2D and 3D Model Integrate Corridor and Site Modeling Both work on same model Use the tools that best fit the situation Target MicroStation Elements WYSIWYG Use Reference Files to Control Display of Model Drainage, Bridges, etc Bentley Systems, Incorporated

14 Corridor Modeling The 3D model is no longer a byproduct of the Design, it is the design. Allows Design Time Visualization Clash Detection Engineering Sanity Bentley Systems, Incorporated

15 Template Library Same Format Additions & Changes Removed Vertical Styles Constraints Superelevation Flags Naming Styles = Feature Definition Targets Renamed Bentley Systems, Incorporated

16 Project to Design Bentley Systems, Incorporated

17 Active Template Enhancements in MR 1 Q&A and Sort Point Feature Definitions Component Feature Definitions Bentley Systems, Incorporated

18 Component Feature Definition Organize by Material Type to Quantify Rendering Design Time Hollywood BIM & Viz Exclude from Top/Bottom Mesh Toggle Bentley Systems, Incorporated

19 Point Feature Definitions Determines if Template Geometry is Drawn Allows Civil Cell with Corridors Separate Feature Definitions for Points on different Layers of Pavement RT_EOP needs to Create Template Geometry and used with Graphical Filter to Create a Terrain model of Proposed Terrain Model RT_EOP_AGGR_BOT does not need template Geometry and is included in the Subgrade Terrain Model Bentley Systems, Incorporated

20 Scalability Design Stages Referencing Target Aliasing & Clipping Tips with Large Models Bentley Systems, Incorporated

21 Managing Corridors Corridor Design Stages Input Template Management Include Critical Sections Output Display Settings Bentley Systems, Incorporated

22 Referencing & Accessing Data Corridor modeling can work across reference files. Because everything is now stored in the dgn, it is necessary to allow the storing and retrieval of all civil information in separate files, and allow all the processes involved to work smoothly across all files and nested references. Processing of Corridor required Read/Write Limits Processing Tree to what lives in Active DGN Bentley Systems, Incorporated

23 Referencing Promotes Federated Workflow Allows long jobs to be broken into several DGNS View All Corridor in one DGN Still cut Sections on All Reference same Geometry and Super Corridors can be split: Contract Construction Staging What makes SENSE Bentley Systems, Incorporated

24 Keep it Simple LEGO Concept Referencing Division of Labor Controls Processing Use Mulitple Corridors and Linear Templates instead of one Template Bentley Systems, Incorporated

25 Target Aliasing and Clipping Used to be combined a corridor could only be clipped by other corridors that targeted it. Target Aliasing and Clipping are now completely separate! Referencing is still key. Target MSTN Elements/Meshes Additionally Clip on MSTN Shapes or Terrains Bentley Systems, Incorporated

26 Tips with Large Models Use of Feature Definition Constraints with Corridor Reference are Costly compared to Point Controls Perform Clipping when Complete or control through Referencing Clips that are Linear/Parallel Consider End Condition Exception Add addition Template drop removing unneeded Components Bentley Systems, Incorporated

27 Tips Reference in Geometry and Super Build Terrains in other DGNs and reference in the Corridor Corridor Updates prevent Terrain Updates More Graphics in 3d Model more to process for Dynamic Sections. Overlay Runs to formulate Profile needs to occur in DGN where Geometry Exists Bentley Systems, Incorporated
