Then, users can start to locate the nodes on the Input Plan. **Note: Object Snapping** Object snapping can be called out either by Ctrl + right-mouse click or by clicking the ‘Snap’ button. # **Drain** Input the drain on the Input Plan by clicking the “**Drain**” button. ![](https://i0.wp.com/mes100.com/wp-content/uploads/2022/09/DRAIN-BUTTON.png?w=1080&ssl=1) To input drains, users have to connect one node to another. Click on the Input Plan while drawing drain will also generate nodes simultaneously. To model a drain without a node, users have to click on “SHIFT + left click mouse”. Instead of clicking, the drain points can also be typed in as coordinates (`x,y`), or as a length and angle (`45<80`). Typing a point as `x,y,z` sets the ground level of the new node there. See [Drive Inputs by Typing Coordinates, Lengths and Angles](https://mes100.com/docs/drive-inputs-by-typing-coordinates-lengths-and-angles/). ## **Importing Drain** To import drains from ACAD, click ‘**Import Drains**’ and select the layer that represents your drain network, and click ‘**Import**’. ![](https://i0.wp.com/mes100.com/wp-content/uploads/2022/09/import-drain-buttons.png?w=1080&ssl=1) ### **Import Drain with ‘Z-values’** When importing drain, users are now able to import the ‘Z-values’ as well. Note: Z-values imported are the drain invert level (IL) If the intention is to iterate the drain invert level (IL), users may check ‘**iterate IL**’ ![](https://i0.wp.com/mes100.com/wp-content/uploads/2022/09/image19-2.png?w=1080&ssl=1) ## **Features of Drain** Click on the drain and right-click to open the features list. ![](https://i0.wp.com/mes100.com/wp-content/uploads/2022/09/image1-4.png?w=1080&ssl=1) 1.
