Mitred elbow: what the app does with it
The free one. Make one by hand, print one, lay them on top of each other. That is the whole pitch.
You give it
| Input | How |
|---|---|
| Pipe and insulation | As on every fitting |
| Bend angle | Any; the mitre is half of it |
| Seam | 7 for a back fastener, 4 for a side fastener, or anywhere on the dial |
| A / B / C / D | Which way the bend hangs, so the lap sheds water and the upper piece is the right one |
| Lap and swage | From Settings |
It gives you
- Two pieces. Swage on the mitre only; plain end square, no swage, because the straight cladding butts to it.
- Holes on the seam lines, both edges. Lap outside the girth, never inside it.
- 1:1 on A4 or A3 with the bar. DXF.
Free means free
No account, no trial clock, no watermark. The same development the paid fittings use. If this one fits your metal, the rest will.
The flat-sided elbow is the same tile with a square section. Same rule: swage on the mitre, plain end plain.
