SVS Clash Guard is a Revit add-in from SVS Tools/SVS Team that brings clash detection and clearance checking directly into Autodesk Revit. Public SVS material describes it as a Navisworks-style coordination tool for native Revit workflows, intended to help users detect model conflicts, review hard and soft clashes, track issue status, and navigate directly to problem areas without exporting heavy models to a separate coordination application.
Primary Purpose
The add-in is designed to reduce the friction of traditional clash-detection workflows by keeping coordination review inside Revit. Standard BIM coordination often depends on exporting models to Navisworks or reviewing cloud-based clash issues through Autodesk Construction Cloud. SVS Clash Guard is positioned as an in-line Revit alternative for faster internal checks, early discipline coordination, and iterative design review before formal model federation or coordination meetings.
In-Revit Clash Detection
SVS describes Clash Guard as having an in-Revit real-time clash engine that can detect physical collisions and clearance-based tolerance violations without requiring model export. This makes it useful for quick checks during active modeling, especially when a team wants to identify conflicts before issuing a coordination model or running a full Navisworks clash test.
Hard Clashes and Soft Clearance Checks
The tool is described as supporting both hard collision detection and soft clearance tolerance checking. Hard clashes identify elements that physically intersect, such as a duct passing through a beam. Soft clashes identify elements that may not touch but violate required clearance space, such as maintenance access, service clearance, or coordination offsets. This distinction is important because many BIM coordination issues are not true geometry intersections but still represent constructability, access, or maintenance problems.
