I'm pretty sure I've used that headline before, but I'm running out of them as we head into the new year.

We've now added Predecessor Types to Associations. O3 supports the following:

These different Predecessor Types can be defined from the IWP Gantt as well.

In the example above, we drew a line from the start of the first Entity to the start of the second Entity, making it a Start to Start Predecessor Type.

You can view an Association's Predecessor Type from the IWP's Predecessor/Successors table.

We've also added the Lag field to Associations.

Go to the Predecessor Entity's Predecessor/Successor grid and then select one of the lines.

The Lag represents the number of days after a Predecessor condition is met that the Successor is ready to go.

Note: this will not automatically adjust constraint dates. This is meant to be used as a tool for sequencing.

We've also included a new system-generated Predecessor constraint for Start to Start Successors.

We'll update your current Predecessor constraints accordingly. E.g., if you're changing a Predecessor constraint to Finish to Finish or Starting to Finish, we'll delete the old Predecessor constraints.

If you're creating a new Finish to Start or Start to Start Predecessor constraint, we'll either create a new constraint (see above) or update the existing ones accordingly.

We've added the Show Group Quantity toggle to the Bill of Materials grid.

When enabling this toggle and grouping by a field (E.g., Drawing), we can see the Quantity totals next to the group.

You can now download multiple models at once from the Models grid view.
