Tool Of The Day:

"Crash-n-Clash"

BIM is awesome until something clashes and start to crash our project deadline…

So let's create a custom Crash-n-Clash tool to find your project clashes before they cause any project crashes.

Today We're Practicing:

>>>

Intersection Filters (Slow/Quick)✨

>>>

Element BoundingBox

>>>

pyrevit Output Table

Let's Create

"Crash n Clash"

Using 7-Step PROCESS

PLAN

🫳No Clashes - No Project Crashes…

You heard the stories of what happens when something is n ot coordinated and clashes on site. Maybe you even experienced it first hand…

So, the Goal for Today:

Create a Crash-n-Clash tool to help us find intersecting elements so we can find and fix them on time right inside of Revit.

We're not replacing Naviswork workflows. Instead, we're making Revit more powerful.

In-Depth Filters:

Notes

🔸BoundingBox Filter

BoundingBox is a quick filter but it's less precise. It can create situations where you'll get elements that do not intersect.

Usually because they're at an angle that makes their BoundingBox expand beyond element to contain it.

🔸Quick/Slow Filter

When possible apply quick filters before you apply slow filter to your collector to improve perfomance.

🔸ElementINtersectsElementFilter Note

There are certain categories that won't work with this filter. Therefore you'd need to extract the geometry yourself and use SolidIntersectsElementFilter by providing geometry.

Code Quick-n-Dirty.

The Goal is to create a proof of concept. Don't try to make it perfect. Skip steps if necessary. Keep it ugly. Keep it slow. JUST. MAKE. IT. WORK…
