Diagonal bars at wall openings

[miguel.gutierrezD74CZ]

Dear community, 

I would love to automate the placement of rebars at wall openings, so far I manage to grab the openings characteristics (points, planes, normal, etc.) thanks to Jeremy post

What I'm struggling with is bending the diagonal rebars if there is not enough room on the wall to place a 1m rebar length:

basically I'm looking forward to replicate this add-in but through Revit API. Any suggestions on which algorithm or api methods to explore to head me into the right direction?

Best regards

Blending the rebars?

Do you mean to calculate their intersection point and cut them off at that point?

That is a simple 2D line intersection calculation.

My bad, I meant to say *bending*, 

From a humble point of view, I'm hijacking your idea to find intersections between line and a plane. So I probably I'll have to loop through the wall faces and make sure the "a" distance be greater than 0.5, other way the rebar will bend a distance "b" in the direction of the plane

See you around Boss !
