# Split 1D elements
This one dialog box is used to split 1D elements or members, depending on the context in which it is opened.
The Split 1D elements dialog box is used to split beams, bars etc. into a number of parts maintaining element releases and offsets as originally defined.
The elements that are to be split must be selected prior to opening this dialog box. Non-1D elements will be ignored.
Open this dialog box by giving the Sculpt > 1D element operations > Split 1D elements menu command or from the Sculpt toolbar when the current view is a Graphic view.
The split may be specified in one of the following ways:
- Split in n equal parts: The selected elements will be split into this many equal parts.
- Split at n [length]: The selected elements will be split into two parts at this many model units of length from the end of the elements. The length can be specified from end 1 or from end 2.
- Split at n %: The selected elements will be split into two parts at this percentage of the way along from end one of the elements.
- Split at existing nodes: The selected elements will be split at every node found within the specified coincidence tolerance along its length. If the Align nodes option is checked then found nodes are moved onto the line of the original element.
- Split at plane: The selected elements will be split where they intersect the specified plane. The plane may be specified by a grid plane or by three nodes. To define the plane by three nodes, first select the three nodes that define the plane; then select the elements that are to be split; then open this dialog box. Selected elements that do not intersect the plane will be ignored.
# Coincident nodes: Use existing nodes where present
When checked, wherever a new node is required during the execution of this operation the program searches existing nodes for one that lies within the coincidence tolerance* of the required position, and uses the first node found instead of creating a new node. Otherwise new nodes are always created.
# Split loads and replace references to old elements with references to new
When checked, loads applied to original elements are mapped onto new elements and, other than in loading records, references to the original elements in element lists are replaced by references to the new elements.
Note: The splitting of loads does not occur where a load is applied to an element because that element is included in a saved list or grid plane that is referred to by the loading record rather than being referred to directly in the loading record list. See Splitting elements graphically for more details.
