SectionBox intersect with other elements

[Ning_Zhou]

is there a way to get intersection point between "4 edges" of SectionBox, and other elements, say a lined based family instance, or simply a model curve?

seems SectionBox don't have any geometry info., the only useful workaround is BoundingBoxXYZ, but again, how can you get "4 edges" of BoundingBoxXYZ?

any hint will be very much appreciated.

just find that section box on specific view cannot be retrieved correctly using the following code, if there're multiple 3D views w/ section box on:
List<Element> sbs = new FilteredElementCollector(doc, v3d.Id).OfCategory(BuiltInCategory.OST_Section).ToList();

seems that v3d.Id filter doesn't make any difference!? so how can you get specific section box on specific view?

i'm still using 2014.

well, seems section box can be directly retrieved from 3d view, overthinking again!

Hi Ning,

BoundingBoxXYZ.Max and BoundingBoxXYZ.Min can return the maximum and minimum points coordinates of the box.

And then you can compose the 4 edges's curve from the above two coordinates.

Hi Ning,

Shall we consider this resolved for the moment, then?

Can you start a new thread if anything else crops up?

Thank you!

Cheers,

Jeremy

thanks Joe, that's what i'm going to use for now even though i'm not quite sure the case of rotated section box.
