Convert elbow 45° to 90° (E45to90)

1. Purpose

Swaps placed 45-degree elbows to 90-degree elbows without deleting and redrawing them. Use it when bends must go square to fit a tight shaft, or when site stock only carries 90-degree elbows.

4. The tool converts each elbow to 90 degrees in place, keeping both connected runs untouched. [image 03: elbows converted to 90 degrees]

4. Real-world example

A 300mm-wide shaft leaves the 45-degree elbows poking out of the wall. Click E45to90, pick the four elbows — they tuck into square corners inside the shaft while both pipe ends stay put.

5. Common errors

Symptom	Fix
Picking changes nothing	You picked a straight pipe — pick an actual elbow fitting (a family instance)
Converted elbow reports a break	The elbow family lacks a 90-degree type for this DN — load it, then rerun
The button is nowhere to be seen	It lives inside the ElbowConvert split menu — expand the arrow to find it
