What is Download Latest?
Download Latest checks your active Revit model for Pirros content (families and details) that has been updated on Pirros since you last downloaded it, and lets you bring the newest versions into your model with a single click.
Think of it as a "check for updates" button for everything Pirros-managed in your current file.
Where to find it
In the Revit ribbon, click the Download dropdown on the Pirros tab, then choose Download Latest.
How it works
When you click Download Latest, the plugin does the following:
Scans your model for Pirros-managed content:
Detail views, drafting views, sheets, legends, and schedules that were downloaded from Pirros
Families (loadable families, system families like walls and floors, model groups, and detail groups) that were downloaded from Pirros
Sends that inventory to Pirros to check whether anything has a newer version available. Content that belongs to a different project (for example, a family you pulled from a Typical project but the current model belongs to Project A) is automatically excluded.
Shows you one of two results:
If everything is up to date, you'll see a short confirmation dialog and no further action is needed.
If updates are available, a dialog opens listing the items that have newer versions on Pirros, along with when they were last synced and whether you've modified them locally.
Lets you choose what to update. Every item is listed with a checkbox so you can pick and choose what to bring in. You can select all, deselect all, or pick individual items.
Downloads and replaces the selected items. Progress is shown as each file downloads and loads into your model.
Confirms success with a summary of how many items were updated.
The update dialog — what you'll see
For each item in the list:
Name of the family or detail
Local Sync Date — when you last synced this item
Locally Modified flag — if you've changed the item in your model since downloading it, it's flagged so you know those local edits will be overwritten if you update it
Legacy flag — for older content downloaded before version tracking was introduced (see "Legacy items" below)
Family types — existing vs new
Families often have multiple types (for example, different sizes of the same furniture piece). When a family is updated on Pirros, sometimes new types have been added that don't exist in your model yet.
Existing types — types already in your model will be replaced automatically with the latest version. No action needed.
New types — types that are on Pirros but not yet in your model are shown in an expandable panel. You can choose which new types (if any) to load alongside the replacement.
System families (walls, floors, ceilings, etc.) and groups (model groups and detail groups) don't use type selection — they're loaded as-is.
Legacy items
Legacy items are Pirros content that was downloaded with an older version of the plugin, before version tracking was added. Because we don't know what version they're on, they appear in the update list even if they're actually current.
For legacy items you have two choices:
Update — re-downloads the latest version from Pirros (same as any other update).
Mark as current — saves the current version info to your model without re-downloading. Use this if you know your copy is already up to date and you just want Download Latest to stop flagging it. Next time you run Download Latest, these items will only appear if a truly newer version is available.
When to use Download Latest
After a teammate uploads an updated family or detail to Pirros and you need the new version in your model
When starting work on a model that's been sitting for a while, to make sure you're working with the latest content
Any time you want to verify your model has the most current Pirros-managed content
Things to keep in mind
Download Latest only looks at content already in your model. To pull in new families or details that aren't in your model yet, use the regular Download command.
Local edits will be overwritten for any item you choose to update. If you've customized a family or detail in your model, check the "Locally Modified" flag before updating. If you want to keep your local changes, don't select that item.
You need download permission. If your Pirros role doesn't include download permissions, you'll see a permission-denied message. Contact your administrator.
You need to be logged in and the model needs to be linked to a Pirros project. If either is missing, the plugin will walk you through getting set up first.
Large models may take a few minutes to check and download. A progress window shows what's happening and can be cancelled at any time.
