# Insert Node

## Insert Node on a Straight Pipe

Nodes can be inserted at any intermediate points along an existing element or bend. Let's look at an example - inserting a node along element 10-12:

Click the toolbar icon. Click on the point along the 10-12 element, where you would like to insert the new node. The following dialog window will be displayed:

In the "Distance from node" field, the node from which distance should be calculated and the distance where the new node should be placed must be input. Indicate the new node number in the "New node name" field. Click OK to create the node and automatically split the element into two parts.

If the node is inserted in  buried elements, soil height for the node is calculate using linear interpolation of soil height at element start and end nodes. Same applies to subsidence and water height. More...

## Insert a Node on a Bend or Elbow

Click the toolbar icon. Click on the point along the bend (top - node 1), where you would like to insert the new node. The following dialog window will be displayed:

In the "Distance from node" field, the node from which distance should be calculated and the distance from the element end (intersection point of this element and bend curve), where the new node should be placed, must be input. Indicate the new node number in the "New node name" field. Click OK to create the node and automatically split the element into two bends, with their own tops (nodes 1 and 5).

The inserted node 4 can be deleted and  moved. If it is deleted, the split elements will be joined into one again.

#### Properties

 Property Description Element length Total value of the element where the node is inserted (from node to node) New node number Number assigned to the new node. Can be assigned automatically by clicking Distance Distance from one of the element nodes to the inserted node Projections If the element is located arbitrarily in space, distance can be calculated as projections on coordinate axes of vectors between the inserted node and the node from which distance is calculated

## Insert a Node on the edges of element

Click the toolbar icon. Click on the element (valve, flange, reducer, tee, etc.). Additional nodes on the edges of the element will be added.

## Insert Independent Node

Used for working with  disconnected pipelines. Point coordinates where the node should be inserted must be indicated.

Coordinates can be input relative to the coordinate center or to any existing node.

When an independent node is input, it automatically becomes a base node.
