What is New Bentley OpenSite Designer CONNECT Edition

The following summarizes the new features and enhancements in this 2019 Release 2.

  • Update of Power Platform to Edition (V10.12.00.54).
  • Subscription Entitlement Service (formerly CONNECT Licensing is utilized. For more information: Subscription Entitlement Service.
  • Includes Bentley LumenRT Designer CONNECT Edition Update 12.
  • Includes Bentley Descartes CONNECT Edition Update 2 (V10.010.00.54).
  • Update of gINT Civil Tools CONNECT Edition Update 1 (V10.03.01.25).
  • Support for following ProjectWise Connect Edition (V10.00.03.167 & V10.00.03.262).

This release is focused on user feedback, lower priority enhancements, fit and finish, and reported defects. The below list highlights some of these items:

  • 2019 Release 2 is backwards compatible with 2019 Release 1. This means DGN files can be opened by 2019 Release 1 once opened by 2019 Release 2.
  • Support for Chord Defined Arcs has been added. This support ranges from Corridors, reporting, and station equations.
  • Several fixes have been done for Save as DWG and Export to DWG.
  • Crossing Geometry Point rule now updates when the parent geometry changes.
  • Resolved an issue where geometry would state invalid element for several commands when it was valid.
  • Corrected issue where clipping was not performed.
  • Improved performance of deleting or un-annotating survey field books.
  • Place label now works when AccuSnap is disabled.
  • Target Alias behavior has returned to have Use Closest off when defining.
  • Dynamic Cross Sections fixes reference attachments when corridor components are not shown.
  • Several superelevation improvements and fixes for overlapping transitions, multi-center curves, user runtime variables, and reports.
  • Superelevation Rule File enhancements.
  • The format of the rule file was updated to support additional user defined variables.
  • A section name is updated automatically when an older rule file is opened in the Edit Rule File dialog.
  • The internal variable ' TransitionLength ' has been renamed ' ComputedTransitionLength ' . Rule files that use ' TransitionLength ' in Custom Key Station equations will likely need to be updated unless ' TransitionLength ' is also defined by a custom equation. This is a manual update that must be done.
  • XML Rule files compatible with both 2019 Release 1 and 2019 Release 2 are included.
  • The delivered superelevation XML rule files have been updated to include the Custom Key Station equation to adjust the transition length to be calculated as a constant relative gradient when using an inside, outside, right, or left pivot. The transition length is calculated using a constant change of slope without the Custom Key Station.

The following summarizes the new features and enhancements in this 2019 Release 1.

General Enhancements

  • Update of Power Platform to Edition (V10.12.00.41). The corresponding MicroStation Update 12 CONNECT Edition version is (V10.012.00.40).
  • CONNECT Licensing is utilized. For more information: CONNECT Licensing.
  • Includes Bentley LumenRT Designer CONNECT Edition Update 12.
  • Includes Bentley Descartes CONNECT Edition Update 2 (V10.010.00.41).
  • Update of gINT Civil Tools CONNECT Edition Update 1 (V10.03.01.08).
  • Support for following ProjectWise Connect Edition (V10.00.03.167).
  • Site Layout tools have been added to rapidly generate conceptual site designs and allow one to move directly to full detailed design tools.
  • Added Explorer, Reference, and Properties icons to the left edge of most tabs on the Modeling ribbon workflow.
  • DGNs with Civil Models are branded with the authoring product, this is referred to as the Product Alignment. The DGN is either OpenRoads, OpenRail, or additionally OpenSite. For more information please see: Product Alignment.
