Step 1 — choose your disciplines
Select every discipline on your project and the tool generates clash rules for every pair automatically.
Step 2 — add element types
Optionally add the element types each discipline uses — skip any discipline to get one general rule per discipline pair instead.
Step 3 — set priorities
Sensible priority defaults are pre-set for every discipline pair. Adjust any pair to match your team's priorities before you generate the matrix.
Step 4 — download your matrix
Review the estimated rule count and discipline list, enter a work email, and download a ready-to-use Excel clash matrix — import it into ClashWise to automate rule matching on your published clash sets.
Frequently asked questions
Is the tool really free, with no account required?
Yes — build and download the matrix without creating a ClashWise account. A work email is required at the final step to receive the file.
Can I use the matrix without ClashWise?
Yes — the Excel file works standalone in any Navisworks clash workflow. Import it into ClashWise's Clash Management tier if you want the rules to auto-match against your published clash sets.
How many clash rules will I get?
One rule per discipline pair, including same-discipline pairs — the tool shows the estimated rule count before you download.
