Karo.Segments handbook.

Karo — Segments is a Revit add-in for placing and managing user-defined segments as plates on host geometry. Use it for flashings, cover strips, drips, panels, cassettes, sheet-material layout, and other linear or planar segments — all sharing the same catalog, schedules, and display workflow.

Opening the plugin

1. On the Karo ribbon tab, click Segments.
2. The hub opens with four sections: Creation & catalog, Schedule, Display, and How to use.
3. Window size, position, and the last section are remembered between sessions.
4. Switch language anytime with the EN / RU toggle in the hub sidebar.
5. Manage license anytime — hold Shift and click the Segments ribbon button (or click the button without an active license to open the activation window).

Creating a segment

1. Fill in the type parameters (or keep the defaults), or select an existing mark in the catalog. The placement form always shows the type and length; other fields are collapsed — click Show all parameters or open the type list to expand them.
2. Click Place.
3. Pick a planar face in the model.
4. Pick a reference edge. While picking: R rotates the plate, Space mirrors it. Magnetic snap engages near segment ends and face corners; otherwise the point moves along the edge in 5 mm steps.
5. After placement, the segment appears in the catalog and in the model as a Karo plate.

In the model

• Edit parameters in the hub or in Revit Properties / native schedules — they share the same fields; invalid values are reverted with a toast.
• Delete a plate with Del (no confirmation); undo with Ctrl+Z.
• Move plates with Revit’s Move tool — the snap anchor moves with them.
• Copy/Paste creates a new segment of the same mark.
• On selected Karo plates: R = rotate, Space = mirror (Revit’s Rotate is blocked for Karo plates).

Catalog

The catalog lists segment marks (types): sizes, check and construction colors, RAL, and instance counts. Rows are grouped by Schedule group; segments excluded from schedules appear separately.

• Click a row to fill the placement form and select matching segments in the model; selecting a plate highlights the catalog row.
• Filter by mark and description with the box above the grid.
• Right-click a row for Place, Edit type, Overlap and side offset, or Delete.
• Shift- or Ctrl-click to multi-select; Delete can remove several marks at once.
• In Per segment mode, a mark has a parent row and nested length/color variants.

Placement, Edit type, Overlap

Mode tabs at the top of Creation & catalog:

• Placement — place new segments for the selected or configured type.
• Edit type — mark, description, sizes, image, RAL, and more; Save applies changes. When selection changes, the form switches to the selected mark (unsaved edits are discarded).
• Overlap and side offset — overlap/gap along length and side offset across width for the selected segments only; the snap anchor does not move.

Length and color modes

• Shared for type — length, RAL, and image are the same for every segment of the mark; edits update the whole type.
• Per segment — length, RAL, and image can differ across length+color groups; other parameters stay type-wide. The catalog shows a parent row plus nested variants.

To change length, color, or image on an existing plate in Per segment mode: select a nested catalog variant or a plate, open Edit type, change fields, and Save. The parent row sets defaults only for new placements.

RAL / construction RGB drive Construction display color; check color drives Check mode. You can also edit Length, RAL, and image from Properties or a Revit schedule. If stored length disagrees with 3D geometry on Per segment marks, use Restore lengths from model in the catalog.

Schedule groups

Groups come from the Schedule group field on segment types.

• Select a group, then Open (existing schedule) or Create (missing schedule).
• Create all missing builds schedules for every group that still needs one.
• If you rename a schedule in the Project Browser or with other Revit tools, the plugin updates Schedule group on every type in that group and will not offer a duplicate.

Excel export

• Export to Excel saves the selected group’s schedule as an .xlsx that matches the Revit schedule look (fonts, colors, borders, merges, column widths) and embeds each type’s image.
• The export is always one continuous table, even if the schedule is split across sheet fragments on a sheet.
• Export all to Excel does the same for every created schedule — one worksheet per group in a single workbook.

Shared parameters (segment type, description, length, width, image, unfolded width, and others) keep the hub, Properties, and native schedules in sync.

Select views (or sheets — the mode applies to all views on the sheet) and click Apply.

Filters help narrow the list: all / 3D / plans / sections / elevations / sheets. The display mode is remembered per view.

Safe to install. Karo.Segments is digitally signed by Karo Modum. Windows SmartScreen may show an "Unknown publisher" notice on first download until reputation builds — this is expected for specialized BIM tools. The installer registers the publisher certificate automatically.

Before you install

• Close all running Revit sessions.
• You need administrator rights on your computer (places add-in files in ProgramData and registers the publisher certificate).
• Supported versions: Autodesk Revit 2023, 2024, 2025, 2026, and 2027 (64-bit Windows).

Step-by-step installation

1. Download Karo.Segments-Setup.msi from your purchase confirmation or download page.
2. Double-click the downloaded .msi file. Windows Installer will launch and prompt for administrative permissions (UAC) to install per-machine.
3. If Windows SmartScreen shows a warning such as "Windows protected your PC":
   • Click More info → Run anyway.
4. The installer automatically detects installed Revit versions (2023–2027), ensures Revit is closed, and seamlessly migrates any previous versions. You can choose full installation or select specific versions manually.
5. Click Install and wait for completion.
   • The setup automatically registers the Karo publisher certificate in the Windows trust store for trusted future updates.
6. When installation completes, start Revit. The add-in loads automatically — look for the Karo tab on the ribbon with the Segments button.

Where files are installed

The add-in is placed in the standard Revit add-ins folder:

C:\ProgramData\Autodesk\Revit\Addins\{year}\Karo.Segments\

(one folder per installed Revit year)

Silent & enterprise deployment

For automated deployment across corporate networks or workstations, run via command line:

msiexec /i "Karo.Segments-Setup.msi" /qn

Digital signature & security

Karo.Segments is digitally signed with a publisher certificate issued by Karo BIM Solutions.

• Automated setup: The installer deploys DLLs to ProgramData and registers KaroBimSolutionsPublic.cer into Trusted Root Certification Authorities and Trusted Publishers.
• IT-managed environments: If Group Policy restricts automated trust registration, administrators can deploy KaroBimSolutionsPublic.cer via Group Policy.
• Data privacy: All segment models, geometry definitions, and Excel exports stay entirely inside your Revit model and local environment.

License & device transfer

• Activation in Revit: To activate your license key or view remaining days, hold Shift and click the Segments ribbon button.
• Device transfer: If you upgrade your hardware or switch workstations, you can transfer your license to the new computer.
• Subscription preservation: Moving or unbinding your license never forfeits or shortens your remaining paid subscription days — the full active period remains available.

Updating

Run the new .msi installer over the previous version. The installer handles upgrades and replaces older files automatically. No manual uninstall required.

Uninstalling

Use Settings → Apps → Installed apps (or Control Panel → Programs and Features), select Karo.Segments, and click Uninstall. Alternatively, right-click the .msi file and select Uninstall, or run msiexec /x "Karo.Segments-Setup.msi" /qn. This cleanly removes the add-in files from all Revit versions.

Compatibility notes

• One installer covers all supported Revit versions; only versions detected (or manually selected) are installed.
• Revit must be restarted after installation for the add-in to load.
• Future Revit versions are included while the product is actively maintained.

Tips

• Start from a catalog mark, then place multiple instances of the same type along edges.
• Use Shared for type when length and color are identical for a mark; switch to Per segment only when variants differ.
• After bulk edits in schedules or Properties, return to the hub to confirm catalog counts and colors.
• Use Check mode to spot plates during coordination; switch to Construction or Drafting for drawings and sheets.
• Prefer Export all to Excel when producing a full package for fabricators or quantity takeoff.

Limitations

• Segments are represented as DirectShape plates today; geometry is driven by segment data, not traditional loadable families.
• Placement requires a planar face and a reference edge.
• Magnetic snap targets segment ends and host face corners within a short range; free placement along the edge uses 5 mm steps.
• Display modes apply to Karo plates only — they do not replace view templates or VG settings for other categories.
• Multi-row catalog delete removes entire marks and their instances after confirmation.

Privacy

The plugin works inside your Revit model. It does not require an always-on cloud service for catalog, schedules, or display workflows.
