Human-Assisted Semi-Automatic Resolver of Clash in BIM

Overview

HUBAROC (Human-Assisted Semi-Automatic Resolver of Clash in BIM) is a guided, human-assisted workflow to prepare the model, detect clashes and resolve them directly inside Revit.
This guide takes you through clash resolution step by step: from model setup to validated results.

23 steps
across 6 phases

Move or Bend
two ways to resolve

Inside Revit
no Navisworks round-trips

Workflow at a Glance

Six phases, 23 steps: follow them in order for reliable clash resolution.

Steps 18–23 repeat as you work through the clash list.

Step 01 – Set Up Revit Before HUBAROC

Phase 01 · Prepare Revit

  1. Open your MEP service model – Open the individual Revit file you want to resolve: Duct, Pipe or Cable Tray.
  2. Link coordination models – Link the Structure, Architecture and other MEP models into this file, and confirm they align before you continue.

Step 08 – Set Maintenance Clearances

Phase 02 · Configure

  1. Enter the maintenance gaps – Enter the clearance you need for ducts, pipes, cable trays and mechanical equipment.
    All values in mm
  2. HUBAROC keeps the gap – When it resolves a clash, HUBAROC keeps this gap between the elements that were clashing.

â–¶ Watch the tutorial

Step 09 – Set Maximum Bend Angles

Phase 02 · Configure

  1. Enter the bend limits – Enter the maximum bend angle, in degrees, that HUBAROC may use for ducts, pipes and cable trays.
  2. HUBAROC stays within them – When HUBAROC bends an element to clear a clash, it never uses an angle steeper than the limit you set.

â–¶ Watch the tutorial

Step 10 – Set Maximum Movement

Phase 02 · Configure

  1. Limit how far services move – Enter the maximum distance, in mm, that HUBAROC may move a duct, pipe or cable tray.
  2. Keep systems in their zone – HUBAROC never pushes a system further than this, so no service is moved out of its allotted zone.
  3. Save your settings – Optionally tick Move air terminals with connected ducts, then click Save Settings and Continue to Simulation.

â–¶ Watch the tutorial

Step 11 – Simulate Project Geometry

Phase 02 · Configure

  1. Choose the project alignment – Select Yes if the model follows a clear North–South alignment. Select No if it has special geometry or no standard alignment.
    Use a 3D view with Section Box on
  2. Start the simulation – Click Start Geometry Simulation. HUBAROC uses your alignment choice to simulate the project geometry before resolving clashes.

Step 12 – Check Connectivity with MHAT

Phase 03 · Connectivity

  1. Set the detection distance – Enter the proximity range, in mm, that MHAT uses to check relationships between nearby MEP elements.
  2. Run the analysis – Click Run Analysis to find disconnected elements that could affect clash resolution and need fixing.

â–¶ Watch the tutorial

Step 13 – Review MHAT Disconnections

Phase 03 · Connectivity

  1. Inspect each disconnection – Use Focus On Error or Open 2D View to review each detected disconnection and the element pair involved.
  2. Choose how to connect – Use Auto Connect to physically reconnect the elements, or Accept the pair as a logical connection for HUBAROC’s resolution.
  3. Save and close – Work through the list with Next, then click Save Changes and Close.
In the MHAT step, open the list of detected disconnections to review them one by one.

â–¶ Watch the tutorial

Step 14 – Group Related MEP Systems

Phase 03 · Connectivity

  1. Create or use groups – Use the existing groups, or click Add Group to collect the elements that belong to one connected MEP system.
  2. Resolve systems together – HUBAROC treats every element in a group together, so a resolution is applied consistently across the whole system.
  3. Move on – In Run HUBAROC, click Next. In Project Configuration, click Finish to save your config.

How HUBAROC Resolves: Move or Bend

Both work on one clash or a whole selection, and both keep the maintenance gaps you set.

Before – The pipe runs through the duct.
Move – The whole pipe run is moved clear of the duct.
Bend – Offsets take the pipe over the duct; the rest of the run stays put.

One Selection, Two Results

In the Bending vs Movement video, the same 32 clashes on a grouped pipe bundle are resolved twice.

Before – The grouped pipe bundle with its clashes.
After Bend – The bundle keeps its route: offsets take the grouped pipes around the obstruction, so the run and its end connections stay in place.
Before – The same bundle and clashes.
After Move – The bundle shifts to a clear spot: the whole grouped bundle is moved to a clear position, keeping the maintenance gaps you set.

Try both on the same selection and keep the result that suits the coordination intent.

Step 18 – Resolve Clashes in HUBAROC

Phase 05 · Resolve

  1. Select a clash – In the Clash Resolution HUD, pick a clash from the Active ClashList, or click Navigate to jump to it in the Revit model.
  2. Choose Move or Bend – Pick the resolution strategy in the selector at the bottom of the HUD.
  3. Click Resolve – Resolve clashes one at a time, or as grouped system elements.

Step 19 – Filter Clashes by System or Element

Phase 05 · Resolve

  1. Highlight System – Click Highlight System to show only the clashes in the selected MEP system.
  2. Filter Selection – Select an element in the model, then click Filter Selection to show only the clashes connected to it.
    Clear Filter shows the full list again

Step 20 – Validate Resolved Clash Results

Phase 06 · Validate & Fix

  1. Check each clash’s status – After resolution, the Status column shows where every clash stands: Unresolved, Approved, Resolved, New Clash, Deleted and Manual.
  2. Update a status – Click a clash’s status to change it from the drop-down list.
  3. Navigate and verify – Click Navigate to revisit each clash and confirm the fix was applied correctly.

Step 21 – Review New Clashes During Resolution

Phase 06 · Validate & Fix

  1. Open Clash Detection – This tab lists any new clashes created while you resolve the main clash list.
    Refresh Clashes updates the list
  2. Add or reject each one – Click Add to put a valid new clash into the main list for Move or Bend, or Reject to dismiss it.

Step 22 – Control Resolution with Logical Pinning

Phase 06 · Validate & Fix

  1. Pin services that must stay – In the Logical Pinning tab, use Pin from Base File or Pin from Linked File to pin services you don’t want moved.
  2. Check what is pinned – Pinned elements are listed below. Highlight Pinned Elements shows them in the model; click x to unpin one.
  3. HUBAROC works around them – Pinned services stay put. HUBAROC resolves clashes using other elements or approaches instead.

â–¶ Watch the tutorial

Step 23 – Fix Post-Resolution Connection Errors

Phase 06 · Validate & Fix

  1. Open Error Logs – HUBAROC logs any disconnections or improper connections created while bending or moving elements. Click Refresh to update the list.
  2. Inspect each error – Use Focus on error or Open 2D view to see the affected elements.
  3. Reconnect and mark – Click Auto connect to make minor adjustments and reconnect the elements, then Mark resolved or Mark unresolved.
