Hi Guys
I’m after a dynamic block that draws a 2D plan of a “Y” branch for a mechanical services (A/C) duct.
If anyone knows if they already exist can they point me to them and I’ll download them.
If they don’t exist can someone please give me a hand by creating these blocks (I can simple scales, arrays, stretches, flips, rotate & do visibility states* so far but that is about it)
There are 2 types of “Y” branch that I want to use (I’ll just use visibility states to swap between the two types).
Branch type 1.
I want to be able to size the width of the incoming duct (incoming duct), change the duct length (incoming duct length) because sometimes they can look a bit weird by either being too short or by being too long, the outgoing duct width I want to scale from the point of their radiused transitions (OD1 from point PA and OD2 from point PB). My problem is the intersection of outgoing ducts 1 & 2 (point PC). Ideally I’d like to get them to meet perpendicular to the other outside duct (like a virtual intersection).
Branch type 2
Again I want to be able to size the width of the incoming duct (incoming duct), maybe change the duct length, scale the outgoing duct width 2 from the start of it’s radiused transition (point PA), scale the outgoing duct width 1 (from points PB)*. And again my problem is the intersection of outgoing ducts 1 & 2 (point PC). Ideally I’d like to get them to meet perpendicular to the other outside duct (like a virtual intersection).
*I’m willing to forgo this if it all gets a bit hard, in that case the incoming duct and the outgoing duct 1 can have the same width.
I’d appreciate any help you can give me with this as it’s driving me nuts.
