Cut automatically
Only certain cases get cut on their own, like a non-load-bearing partition.
Pipes cross walls.
Nevic Clash cuts the openings.
Nevic Clash finds where pipes and ducts cross a building's walls or structure, then cuts the
openings you can safely cut, all at once.
Because this can lead to a large edit, it only acts where it's certain, and leaves the rest
for a person to review.
Free, with no account. Your model never leaves your PC.
THE FLOW
From clash report to opening.
Feed it the clashes and it sorts them into what's safe to cut and what gets reported.
Clash report / model
A Navisworks report, or the whole model
Nevic Clash
Identify → cut. Two steps.
Openings + reported list
Anything needing judgment is reported separately
INPUT
Feed it a Navisworks clash report and it looks at only those hits. Without one, it sweeps the whole model and its links.
AFTER CUTTING
It checks the clashes again afterward, to confirm they improved.
WHY BOTHER
Not just finding. Cutting, too.
Clash detection stops at the list of collisions. Judging each one and cutting the opening is what this does.
REVIT · NAVISWORKS
Clash detection
- 1Finds where things collide and hands you a list.
- 2Whether that wall carries load is for a person to check against the drawings.
- 3Every hole that is safe to cut gets sketched by hand.
- 4If it's unclear, ask whoever owns that call.
- 5Repeat, hundreds of times.
Finding is where it stops. It cuts no openings at all.
NEVIC CLASH
After the finding
- 1Takes that list as it is, or scans the model itself.
- 2Sorts out what is safe to cut, by rule.
- 3Everything safe to cut gets its opening, all at once.
- 4Checks each cut spot again afterward.
- 5Anything needing judgment is reported as a list.
Walls inside linked files are handled too, with a backup written first.
SAFETY BY DESIGN
Only what's safe. The rest comes back as a list.
Because this can lead to a large edit, it only automates what's certain and reports anything uncertain as a list.
Reported as a list
Load-bearing walls, exterior walls, below-grade, and fire-rated assemblies are reported as a list.
Two clicks to run
Identifying and cutting are separate steps, so nothing runs on a single click.
WHAT IT DOESN'T DO
Limits
- Openings cut in a linked file cannot be undone with Ctrl+Z. Openings in the model you have open undo in a single step. A linked file gets saved, so a backup is written next to the original before cutting.
- Judgment follows the data in the model. If a wall carries structural load but the model doesn't mark it, Nevic Clash has no way to know.
- Anything uncertain is reported instead of being handled automatically.
