Thanks to the built-in interference check tool, Revit clash detection helps catch clashes like pipes cutting through beams or ducts blocking essential spaces, long before they become real-world disasters. But identifying issues is only step one, resolving them without delaying the project is where true coordination expertise shines. In this article, we\u2019ll break down how Revit clash detection works.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_Is_Clash_Detection_in_Revit_and_How_It_Works\"><\/span>What Is Clash Detection in Revit and How It Works?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Clash detection in Revit is about catching design conflicts before they hit the construction site. The interference check tool scans your model to spot where elements, like a duct crashing into a beam, overlap. You can run these checks between elements in your main model, bits in linked Revit models, or even against linked IFC files.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">When conflicts pop up, Revit spits out an interference report: a tidy clash report listing every pair of offending elements, their categories, and their Element IDs. Click \u201cShow\u201d, and Revit zooms straight to the problem so you can tweak a beam, nudge a duct, or re\u2011route cable trays on the spot. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">While it\u2019s great for hard clashes, soft clashes (like clearance issues) or workflow clashes (scheduling conflicts), you often need extra tools or processes. But still, as a quick sense\u2011check during design, Revit interference check gives architects, engineers, and <a href=\"https:\/\/interscale.com.au\/blog\/what-is-a-bim-coordinator\/\">BIM coordinators <\/a>a live view of potential headaches<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Revit_vs_Navisworks_for_Clash_Detection\"><\/span>Revit vs Navisworks for Clash Detection<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">While Revit and Navisworks tackle clash detection, they come at it from different angles and are suited for different jobs. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Revit interference check shines when you want instant feedback inside the authoring tool. No exports, no waiting. Just pick categories and run. However, it mainly deals with Revit (RVT) and IFC files, can chug a bit on massive models, and offers fairly basic reporting. And it&#8217;s mostly focused on those hard clashes we talked about. When you&#8217;re trying to manage and visualise hundreds of clashes with Revit, your project can get messy pretty quickly.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For bigger, multi-disciplinary jobs, Navisworks Manage steps up. Its clash detective feature handles a wider range of file formats, creating a federated model for comprehensive <a href=\"https:\/\/interscale.com.au\/blog\/what-is-bim-clash-detection\/\" target=\"_blank\" rel=\"noreferrer noopener\">BIM clash detection<\/a>. It catches hard clashes, soft clashes (like clearance issues), and even duplicates, with custom tolerances and advanced filtering. Navisworks\u2019 clash report is detailed, and its 3D visualisation makes managing clashes a breeze. The problem is, it&#8217;s a separate tool, not native. So, you need model exports.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"How_to_Find_Navisworks_Clashes_in_Revit\"><\/span>How to Find Navisworks Clashes in Revit?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Finding Navisworks clashes in Revit can feel like a puzzle, but it\u2019s manageable. Start with Navisworks\u2019 clash report, which lists clashing elements and their IDs. Manually, you can copy these IDs into Revit\u2019s \u201cSelect by ID\u201d tool to locate them. Navisworks\u2019 SwitchBack feature tries to automate this, zooming to the element in Revit, but it\u2019s not always reliable.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For efficiency, try a Revit clash detection plugin like Clash Navigator. It lets you import Navisworks reports directly into Revit, visualise clashes, and track resolutions. This cuts down on tedious back-and-forth, keeping your BIM coordination smooth and focused.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"How_to_Do_a_Clash_Detection_in_Revit\"><\/span>How to Do a Clash Detection in Revit?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Doing a clash detection in Revit is straightforward with the right approach. Start by ensuring your model and linked files are up-to-date. In this phase, a good BIM integration is key. Head to the \u2018Collaborate\u2019 tab, click \u2018Interference Check\u2019 under *Interference Check\u2019, and select categories to check, like ducts versus beams. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Specific selections save time. Run the check, and Revit generates a clash report listing conflicts with element IDs. Use the \u2018Show\u2019 button to view clashes in the model, then tweak elements to resolve clashes in Revit. Hit \u2018Refresh\u2019 to update the report. Export it as HTML for sharing.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">But Revit clash detection isn\u2019t a solo act. It\u2019s part of a continuous BIM coordination cycle. <a href=\"https:\/\/interscale.com.au\/blog\/benefits-of-bim\/\">To get the edge of BIM<\/a>, you must set up a solid integration framework to make the process efficient. Let&#8217;s say like tidy file links, shared naming conventions, and clear coordination rules.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The best practice here is to integrate checks into your weekly sprint. Tie each clash to an assignee in your CDE, note the proposed fix, and track status until closed. Running a <a href=\"https:\/\/interscale.com.au\/services\/bim-audit\/\">BIM audit<\/a> at this stage helps ensure the model stays clean and your clash\u2011free status sticks. When things get hairy, mixed file formats, clearance rules, or 4D sequencing, export to Navisworks or loop in Interscale\u2019s BIM integration crew to keep coordination orderly.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Recommended_Plugins_and_Tools_for_Clash_Detection_in_Revit\"><\/span>Recommended Plugins and Tools for Clash Detection in Revit<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Revit\u2019s Interference Check is a solid start, but plugins and tools can extend its functionality significantly.
