Hello , i was able to place a family instance at the point of intersection between duct and a beam but for some reason there is this one beam that i m not able to find the intersection which is very weird cz the other beams are fine (i can find intersection and place an element) . for some reason my intersection function doesnt work on that beam i know that s sounds weird and mayeb stupid so i need some help
this is the function
and this is how i use it i
That does not sound stupid at all, nor weird. The intersection method may be behaving unexpectedly, or the duct curve may not be what you think. One step towards debugging this may be to display the input fed into the intersection method graphically, e.g., generate a model line to represent the duct curve and check that it really does intersect the face. Another option would be to implement your own intersection method to gain greater control and be able to analyse the internals of the method. This is straightforward to do if the face is planar and the duct curve is a straight line. As a last resort, you could hone the situation down to produce a complete minimal reproducible case for further analysis:
