The SSI 2020 installer now includes ShipExplorer, a new addition to the SSI product family.
The existing capabilities found within Navisworks Manage is now partnered with ShipConstructor to provide you with the ability to share design changes and communicate complex data models across local and wide area networks, all with the click of a button.

ShipExplorer is a Navisworks Manage plugin that enables existing ShipConstructor files to be easily managed and viewed from within Navisworks.

ShipExplorer provides you with the ability to:

  • Load from ShipConstructor directly, or from NWF and NWC files;
  • Use the switchback feature to open the related model drawing within ShipConstructor;
  • Load and compare revisions between model drawings;
  • Load the product hierarchies and create sets from the hierarchies for easy navigation, and
  • Use the embedded Search tool to find specific parts.

Note that with this release, ShipExplorer requires both Navisworks Manage and ShipConstructor to both be installed.

Adding Navisworks and ShipExplorer to your tool-kit streamlines your shipbuilding activities and makes collaboration easier than ever.

Clash Manager UDA Improvements

SSI 2020 includes a number of improvements to help you use the Clash Manager and Clash Palette features more effectively.

  • Clashes now support the use of String Lists for User Defined Attributes (UDA’s) as defined in Manager, which provide list options for users to choose from within the clash palette and Clash Manager in ShipConstructor;
  • Now, you can add multiple options to the clash UDA selections, thereby reducing data entry errors and providing standardized options for users to select, based on your requirements;
  • Once selected, the clash UDA options selected are then also visible from the Properties Palette, from within Navisworks, and the Object Enabler as read only options;
  • Furthermore, once you have searched for clashes and they appear in the Clash Manager or Clash Palette, you can now zoom to the clash directly, simply by right-clicking on the listed item and selecting “Zoom to clashing Part”;
  • This can dramatically save time and frustration, especially when dealing with a complex model, or multiple components.

SSI is continually working towards making it easier for you to efficiently perform tasks such as clash detection, which is why improvements to the Clash palette such as list UDA’s and the new “Zoom-to” features will save time and help reduce errors.

Clash Manager

Weld Revisions

ShipConstructor 2020 WeldManagement now supports tracking and review of weld revisions across the entire model.
While revisions have previously been available for other components within ShipConstructor, the ability to track weld revisions provides a whole new level of rigor in viewing and understanding weld changes made to the project over time.

Weld Revisions can now be viewed using one of three methods:

  • From the project Revisions, or Part revisions palette where synchronized welds, modified welds, deleted welds and added welds are all tracked and displayed;
  • By using the Task Manager to record and display a Revisions summary, where weld modifications can be tracked by user and for specific changes made within the task list window;
  • And by using PublisherLT to create output based on revisions remotely. where you can create reports and outputs for weld changes even when not connected to ShipConstructor.

Weld now displays Revisions for the following properties, (including Standard, Auto Standard and UDA)for any object:

  • Weld Paths;
  • Weld position within the product hierarchy;
  • and Weld pin and unpins.

The following changes are not tracked:

  • Changes to weld types;
  • Changes to the weld standards;
  • Changes to the weld schedule;
  • Changes to the weld status;
  • Changes to the definition of UDA’s;
  • Changes to the parts the weld is associated with.

Keep track of changes on an individual user level, unit level or project level and be able to access and share that data from a variety of locations to suit your needs.
