# HOW TO CHANGE NODE SIZE IN GRAPHIC USER INTERFACE (GUI)

You can configure how nodes (e.g., **sumps, manholes, and fittings**) are displayed in the Key Plan. Nodes can either be shown using their **actual physical dimensions** or **scaled based on the node mark text height**. 

Go to: 

*Options > Project Settings > Drainage/Sewerage/Water Ret > Detailing > Key Plan/ Plans > Node Size*

| **NODE SIZE SETTINGS** | **DESCRIPTION** |
| --- | --- |
| True dimension | Displays the node using its**actual physical dimensions** based on the assigned sump, manhole, or fitting profile. ![](https://i0.wp.com/mes100.com/wp-content/uploads/2026/07/True-dimension.png?resize=1080%2C538&ssl=1) |
| Text Based | Displays the node size based on the**height** defined in the “**D-NodeMark”** layer, regardless of its actual physical dimensions. ![](https://i0.wp.com/mes100.com/wp-content/uploads/2026/07/Text-Based.png?resize=1080%2C537&ssl=1) Scale Ratio: Height to Node Size **1 : 1.2 m** A text height of **1 unit** corresponds to a displayed node size of **1.2 m**. |
