Clash panel

Resolve Clash

Point at two faces and slide the selected object until it clears, then read off exactly how far it moved.

What it does#

Objects clash, and the usual next step is to drag one with Item Tools until it clears, read the offset and type it into the authoring tool. This does the dragging. Select the object that should move, point at the face of it that is in the way and the face it must clear, and it slides exactly far enough along those faces' normal, then tells you how far, ready to type into Revit.

How to use it#

1. Select the object that should move, say the pipe.
2. Click Resolve Clash. The native Point to Point measure opens and the banner along the bottom of the window asks for the face of the pipe that must move.
3. Click the underside of the pipe. The banner now asks for the face it must clear.
4. Click the top of the beam. The pipe slides up until its underside is past the beam's top plus the clearance, and a dialog reads "Moved Pipe 1234 by 152 mm".
5. Click Copy in the dialog and paste the bare distance into the authoring tool. Ctrl+Z puts the pipe back in Navisworks.

Limitations#

• Only the two faces are considered. A part of the object that sticks out past the face you clicked is not checked against the obstacle.
• The two faces must be parallel. A vertical face against a beam top is refused on the banner, and nothing moves.
• The move is a Navisworks transform, the same one Item Tools makes. It changes the review model only, never the source file; the number is what goes back to the author.
• Faces already clear are reported with their gap and left alone; set a clearance to push them apart anyway.

Other uses#

• A quick "what if": move the pipe, see whether it now hits the ceiling, undo.
• Sloping soffits and rotated walls work as well as floors, because the faces come from the objects' own triangles rather than the world axes.

Good to know#

Esc, a right-click or choosing another tool cancels quietly. The clearance is stored with its unit in resolve_clash.json, so 25 mm stays 25 mm in a feet-and-inches document.
