(c# revit 2019)I want to make sure that it has touched the surface. I want ElementtouchedElementFilter, A surface face to each other, A surface joint together

[klkl12234]

This is a code that examines interference.

ElementIntersectsElementFilter elementIntersectsElementFilter = elementIntersectsElementFilter = new ElementIntersectsElementFilter(fs);
var filters = new FilteredElementCollector(doc)
.WherePasses(elementIntersectsElementFilter)
.ToList();
if (filters.Count == 0)
{
continue;
}

This is a code that examines touched.

ElementTouchsElementFilter elementTouchsElementFilter = elementTouchsElementFilter = new ElementTouchsElementFilter(fs);
var filters = new FilteredElementCollector(doc)
.WherePasses(elementTouchsElementFilter)
.ToList();
if (filters.Count == 0)
{
continue;
}

However, there is no function called ElementTouchsElementFilter.

I want ElementTouchsElementFilter

I want to make sure that it has touched the surface.

What I'm working on is a square duct.

Is there a way to check the touched side?

Is there a way to test the a surface joint together?

Is there a way to test the surface face to each other?

Sorry, I am not good at English, so I used a translator.

Thank you!

It sounds as if your needs are pretty specific and you need precise results.

In that case, to move forward faster, I would suggest using the existing bounding box, intersection, and containment filters for a rough first approximation and adding your own more careful and precise geometric analysis afterward.

For the rectangular planar faces of a rectangular duct, this kind of geometric analysis is not very hard to implement yourself.

Good luck and have fun!
