With “Node”, “Drain” and “Catchment” buttons, a drainage network system can be easily created in the CAD Drawing.
Node #
Input the node in the drawing by clicking the “Node ” button.

To input the node, users have to click once on the Input screen. Then, users can start to locate the nodes in the drawing.
Note: Object Snapping
Object snapping can be called out either by Ctrl + right-mouse click, or clicking the ‘Snap’ button.
Node Shape #
Starting from MiTS 2.5, node shape can be selected either to be displayed by ‘Square or Circle’
To change the node shape, go to Project Parameters > Drainage > Detailing > Key Plan > Node Shape > select shape
Drain #
Input the drain to the drawing by clicking the “Drain” button.

To input drains, users have to connect one node to another. Click on the screen while the drawing drain will also generate nodes.
To model a drain without a node, users have to click on “SHIFT + left click mouse”.
