What you will achieve
- Move, insert, and delete intermediate vertices.
- Distinguish the drawing from the pipe's hydraulic properties.
Step-by-step tutorial
How to edit pipe geometry
Move, insert, and delete drawing vertices, then use Cancel, Apply, and Undo without rebuilding the pipe.
Before you start
- Load a copy of your model and select a pipe with intermediate vertices.
- Record its ID and length before editing.
Open route editing
Select the pipe and open Edit drawing vertices. Endpoints belong to the nodes; the tool changes only the intermediate points in the drawn route.
- Confirm the ID before editing.
- Zoom in enough to distinguish each vertex.
Move, add, or remove points
Drag a point to correct its position. Insert another to represent a bend, and remove only the unnecessary intermediate point.
- Cancel discards the draft.
- Apply saves the new route.
- Undo reverses a correction applied by mistake.
Verify what changed
Select the pipe again and compare its ID, endpoint nodes, and properties. A changed drawing does not by itself mean hydraulic length was recalculated from geometry.
Do it in WatDis
- Move a vertex and use Cancel.
- Repeat, apply the change, and use Undo.
- Compare ID and length before and after.
Common mistakes
Moving a node by mistake
Vertex editing targets the intermediate route; confirm the endpoints before dragging.
Inferring a new length
A visual change alone does not prove that hydraulic length changed.
