1. Purpose
Bends a running horizontal pipe straight down at 90 degrees at the picked point. Use it when a horizontal run reaches a shaft and must drop, or must plug down into floor-mounted equipment.

3. Steps
- Open a view where the run is clearly visible — 3D or a section works best. [image 01: the horizontal run above the shaft]
- Click Dw90 in the VP_MEP tab, Draw 3D panel.
- Pick one point right on the pipe body. [image 02: the picked point on the pipe]
- The tool draws a downward leg 300mm long by default, elbow included. Press Esc to cancel. [image 03: the finished drop leg]
4. Real-world example
A DN110 horizontal drain reaches the shaft and must drop to the floor below. Click Dw90, pick a point at the shaft mouth — the vertical drop plugs straight into the stack with no manual elbow sketching.
5. Common errors
| Symptom | Fix |
|---|---|
| "Selected element is pinned." | The pipe is pinned — unpin it, then rerun |
| Clicking draws nothing | You missed the pipe — pick a point exactly on the pipe body |
| Elbow faces the wrong way | The pick was too close to the old pipe end — pick mid-run instead, then rerun |
