Design model features example library

The Design Model Features Example Library consists of model representations of individual roadway features commonly found on WisDOT roadway projects. The examples in the library establish Level of Detail (LOD), and content expectations for Design Model deliveries on WisDOT design projects. Using 3D objects to improve the communication of design model delivery expectations will promote efficiencies in roadway design, and will promote greater consistency in our design model deliveries.

Additional information about the purpose of the Design Model Features Example Library can be found at Design model standards update

Examples in the design model features example library will be classified as Base Level of Detail (Base LOD) or Advanced Level of Detail (Advanced LOD). Base LOD examples establish the minimum level of detail required for representation of a feature in a design model. Advanced LOD examples establish delivery requirements for optional higher level of detail representations of a feature in a design model. Decisions to elevate level of detail to advanced levels for specific features in a project's design model are made by Region offices, and documented using a design model scope summary form (form currently being developed). See "Project design model scope decisions" discussion in Design model standards update for more information.

Model examples files will consist of:

• surface models as DTMs in LandXML
  • provided for transfer of complete surface model as a DTM object
• surface model breaklines as polylines in AutoCAD DWG
  • provided to demonstrate the location, and configuration, and the expected level of detail of breaklines for proper feature representation in design model deliveries
• surface model TIN as 3D Faces in AutoCAD DWG
  • provided as an example of a required format for Triangulated Irregular Network (TIN) representations of features in design model deliveries
• Source Civil 3D design files.
  • Provided as a resource to help designers see how the model example could be developed. It is important to understand that the purpose of model example library content is to communicate design model delivery requirements, it is not intended to communicate the best, most recent roadway design workflows. The model example source Civil 3D design files will not be maintained as Civil 3D roadway design workflows are improved. The C3DKB Civil 3D training is the source of our most current roadway design workflow information.
  • Civil 3D design data is not a design project design model deliverable.
• Surface model contours as polylines in AutoCAD DWG
  • Provided as an alternate visual representation of surface model geometry.
  • Contour files are not a design project design model deliverable
• 3D PDF files for non-Civil 3D users
  • Provided to allow non-Civil 3D users an opportunity to review model example files and concepts. 3D pdfs of breakline files, 3D Faces files, and contour files are provided.
  • 3D pdf files are not a design project design model deliverable.
  • NOTE: We are planning to implement a future solution for non-Civil 3D user review of model example files that will utilize an internet browser-based model viewer. When implemented, the browser-based model viewer will replace 3D pdf model example files.

WisDOT Design Model Guidance Team site introduction

https://trello.com/designmodelguidance

Welcome to WisDOT Design Model Guidance Team on Trello. WisDOT Design Model Guidance is a place to interact with the Methods Development team and other WisDOT Design Model standards development followers. You can use this platform to do things like:

• Propose new model examples
• Comment on proposed, DRAFT, and GUIDANCE status model examples
• Submit revisions to consider for existing model examples
• Submit new model examples for idea exchange

WisDOT Design Model Guidance team members have full access to participate in the discussions about design model standards. To join the team, send a request to support.cae@dot.wi.gov. Before joining the team, please review the WisDOT Trello disclaimer.

On WisDOT Design Model Guidance you will find 4 boards:

1) Suggest Features for Future Examples

2) Comment on Features in Example Development Queue

3) Comment on DRAFT Model Examples

4) Comment on GUIDANCE Model Examples

Please review the "How to use this board" list found in each board for information on how to make the most of your WisDOT Design Model Guidance team participation.

Only WisDOT Design Model Guidance team members can comment on idea cards found on this board. You can request team membership by sending an email message to support.cae@dot.wi.gov. You will receive a team membership invitation email message. If you don't have a Trello site account, you will be prompted to create one when you join the team.

Only members of a given board can add ideas cards to that board. To become a board member, you must first become a WisDOT Design Model Guidance team member (see above). Once you've joined the team, click Join Board on the top of the board.

All content of these boards is visible to anyone on the internet. The source of content is also publicly visible. If you would prefer to provide comments or ask questions about our design model guidance effort anonymously, send your comments and questions by email to support.cae@dot.wi.gov with "design model guidance comments" in the subject line of the message. We may ask you if we can share your comments on the Trello boards without identifying the source, but we will not do that without your permission.

Tip: To get started on any board, review the How to use this board list within the board.

1) Suggest Features for Future Examples board

The 1) Suggest Features for Future Examples board is the place for submitting suggestions for new features to be considered for development and addition into the WisDOT Design Model Features Example Library.

2) Comment on Features in Example Development Queue board

The 2) Comment on Features in Example Development Queue board consists of a list of roadway features for which MDU will develop model examples. This board provides an opportunity for people to provide input on proposed model examples - early in the development process.

3) Comment on DRAFT Model Examples board

The 3) Comment on DRAFT Model Examples board consists of a list of roadway features for which DRAFT status examples are available for review. This board provides an opportunity for people to ask questions and provide comments on DRAFT status model examples. Methods Development will respond to comments and questions.

Example model files are available for download from the WisDOT Civil 3D Knowledge Base (C3DKB), links to example downloads are found in the example cards.

4) Comment on GUIDANCE Model Examples board

The 4) Comment on GUIDANCE Model Examples board consists of a list of roadway features for which GUIDANCE status examples are available for review. This board provides an opportunity for people task questions and provide comments on Guidance status model examples. Methods Development will respond to comments and questions. Examples listed on the board are in GUIDANCE status and are deemed ready for use in roadway design practice.

Example model files are available for download from the WisDOT Civil 3D Knowledge Base (C3DKB), links to example downloads are found in the example cards.
