1. Quick Dim Panel

Accelerate MEP shop drawing annotation with intelligent automated dimensioning and category-specific tagging for pipes, ducts, cable trays, conduits, and fabrication parts.

1.1. Gen Dims (Auto Dimension & Tagging)

Automatically generate dimension strings and category tags across selected elements. Select elements first (pre-selection) or run the command and pick elements individually.

Works seamlessly across Floor Plans, Sections, and 3D Isometric Views with built-in anti-overlap intelligence.

1.2. Purifying (Batch Clean-up)

A specialized drafting cleanup utility. Selectively batch-delete dimensions, tags, model lines, or detail lines, and toggle the visibility of reference lines/planes in the active view or across the entire project in seconds.

1.3. Dimension Settings

Fine-tune dimension placements, offsets, reference lines, fitting inclusion, and auto-tagging families.

• Insert Dimensions: Choose between measuring to the geometric center of fittings or capturing exact linear cut lengths.
• Insert Tag: Automatically place annotations alongside dimensions with custom leader offsets and category-specific tag types.
• Dimension Style & Offsets: Pick active Revit Dimension Types and adjust standoff distances.
• 3D View Orientation: Lock dimension orientation planes when annotating inside 3D views.

2. Tags Panel

Clean up annotation layouts and keep drawing sheets strictly aligned and compliant with BIM drafting standards.

2.1. Align Vertical

Align scattered tags along a vertical datum. Select multiple tags (by window or individual selection) and pick a reference point; the tags snap into a neat vertical column with orderly, legible leaders.

2.2. Align Horizontal

Align tags horizontally along a common datum line while adjusting their positions and maintaining clear leaders and host associativity.

2.3. Straighten (Collinear Tag Leaders) New

2.4. Perp. ⊥ (Perpendicular Tag Leaders)

Instantly toggle tag leader elbows to form clean 90-degree right angles relative to their tagged MEP host elements for crisp, professional drawings.

2.5. Tag Settings

Configure default selection preferences (window rectangle vs. click-and-finish) and set uniform spacing intervals between adjacent aligned tags.

3. MEP Family Panel

Manage, place, orient, and support Revit families with high-productivity browser and array tools.

3.1. Family Browser (Folder & Internal)

The Family Browser pulldown provides instant access to two specialized dockable panels:

• Folder Browser: Browse, preview, search, manage, and drag & drop Revit family files (.rfa) directly from your local hard drive or corporate network folders without pre-loading them into the project.
• Internal Family Browser: Toggle the dockable Family Browser pane to browse, search, inspect, batch-rename inner family types, or manage loaded families in the active document.

3.2. Flip Rotation

Quickly rotate any selected family by a custom specified degree or flip it 180 degrees with a persistent floating modeless panel for continuous clicking without closing the tool.

3.3. Smart Alignment (3D Bounding Box)

Select two or more fittings, equipment, or accessories to align them along Left, Right, Top, Bottom, or Elevation edges based on their 3D bounding geometry.

3.4. Hangers & Supports

Automatically place and array level-based or face-based hangers and supports along selected pipes, ducts, cable trays, or conduits.

Configure start and end offset margins, specify distribution intervals, and anchor hanger rods directly to overhead floor slabs or structural ceilings.

4. MEP Routing

Intelligent 3D auto-routing algorithms that connect open ports, faces, and branch lines with full fitting resolution.

4.1. To Connector

Connect two open MEP connectors in 3D space with a single click. Select two open connectors on pipes or ducts; the engine computes an orthogonal 3D path with required elbows and provides alternative route cycling.

4.2. To Point

Route from an open connector to any picked coordinate on a face of a wall, floor, or ceiling (including linked models).

4.3. Branch Connect (Tee, Wye, Tap)

Connect an open connector to a target main pipe or duct using three specialized routing tools:

• Branch Tee: Generates an orthogonal branch connecting into the main run with a 90° Tee fitting.
• Branch Wye: Routes an orthogonal branch entering the main line at a smooth 45° angle with a Wye fitting directed towards the connector (ideal for drainage, waste, and vent plumbing).
• Branch Tap: Connects directly to the main duct/pipe surface with a Takeoff/Tap fitting without breaking the main run geometry.

4.4. Random Cycle

Quickly rotate through alternative mathematical routing trajectories if the initial auto-routed path (To Connector, To Point, or Branch Connect) does not match your spatial preference.

5. MEP Tools

5.1. Smart Align Branch Upgraded

Select a straight main MEP element and a branch element. Smart Align Branch automatically analyzes the spatial geometric relationship between them to achieve a perfect 3D connection without breaking existing fittings:

5.2. Bloom (Port Extensions)

Automatically create pipe or duct stub extensions radiating outwards from all open connectors on equipment or fittings in continuous picking mode.

5.3. Move And Connect

Pick a static target element, then pick the element you want to move; the tool automatically rotates and translates the second element so their closest open connectors meet and connect directly.

6. MEP Fittings

A dedicated suite of quick-fitting generators to speed up manual drafting of elbows, tees, taps, and transitions.

6.1. Elbow (In-Canvas 3D Gizmo)

Pick a connector position on a straight pipe, duct, cable tray, or conduit. An interactive in-canvas 3D direction gizmo appears, allowing you to choose 90° or 45° angles and stub extension lengths with interactive visual confirmation.

6.2. Vertical 90° Elbows (90 Up / 90 Down)

6.3. Tap / Tee Connect Updated

Connect a branch pipe/duct or any open fitting connector to a main run. Automatically detects geometry, creates required connecting segments, and inserts a Tap or Tee junction smoothly, even if the elements are skewed or offset.

6.4. Gen Tee / Wye

Pick a point on a straight pipe or duct to split it and insert a Tee or Wye fitting. An in-canvas 3D route gizmo appears to let you click a ray to generate a 90° Tee or 45° Wye branch fitting.

6.5. Reducer, 90° to 45°, & 45° Elbows

Accessible via the ribbon slide-out panel for advanced fitting creation:

• Reducer: Pick 2 points on a straight Pipe or Round Duct to configure sizes and insert a reducer/transition fitting at the first point, midpoint, or second point.
• 90° To 45° Elbow Conversion: Click on any standard 90-degree pipe elbow to convert it into two 45-degree elbows with an automatically calculated gap based on pipe material and diameter standards.
• 45 Up / 45 Down: Instantly generate vertical 45-degree upward or downward elbows at pipe or duct endpoints.

7. MEP Clash

7.1. Clash & Wall/Floor Sleeves

Detect interference issues between MEP systems and target structural categories (including linked models). Automatically generate wall/floor penetration sleeves and isolate clashed elements for review.

7.2. Clash Solver (Bypass Loops)

Solve clashes automatically by adding 45° or 90° bypass offset loops around obstacle elements with configurable safety clearances.

Offset = (Obstacle Outer Boundary - Pipe Centerline) + Pipe Outer Radius + Clearance Offset

8. Selection Panel New Panel

High-efficiency MEP selection tools to rapidly traverse connected networks and refine selections by granular parameters.

8.1. Pipeline (Select Pipeline)

Instantly select entire connected MEP runs (pipes, ducts, fittings, valves, and accessories) with a single click — no dialog prompt required. The command directly executes using your pre-configured Pipeline Settings for lightning-fast workflows.

8.2. Pipeline Settings

Configure the default traversal behavior and input picking mode for the Pipeline command:

• Selection Modes:
  • All Connected: Traces all continuous physically joined MEP elements across fittings and accessories, regardless of system classification.
  • Same System: Follows connected elements strictly restricted to the same MEP system.
  • All in System: Selects all elements in the active document belonging to the target system.
• Pick Modes: Toggle between selecting a single seed element or picking multiple seed elements to initialize the trace.

8.3. Selection Filter

Dynamically filter selected elements in a hierarchical tree view grouped by Category, Family, and shared parameters to refine the active Revit selection in real time.

9. MEP System

9.1. Assign System

Select a pipe or duct to view all available Piping and Mechanical system types in the project and quickly reassign the element’s system classification.

9.2. Delete System

Delete the MEP system instance associated with a selected element (either directly or via connectors) without deleting the physical pipes, ducts, or fittings.

9.3. Disconnect Elements

Select two connected elements (e.g., pipe and fitting) to safely disconnect their touching connectors, leaving them unjoined without changing their position.

10. MEP Plus

10.1. Break Segment

Click two points along a straight pipe or duct to delete the middle segment and divide the element into two independent runs while preserving outer connections.

10.2. Split with Unions

Batch-split straight runs of pipes, ducts, conduits, or cable trays at specified regular interval lengths with automatic Union fittings at split points (with options for start and end unions).

10.3. Set Distance

Position parallel MEP curves at exact distances (center-to-center or edge-to-edge horizontally or vertically) based on custom spacing inputs.

10.4. MEP Offset

Offset selected pipes, ducts, conduits, or cable trays by a specified distance and direction, with options to create parallel copies or move existing elements.

10.5. Ref Level
