In Advance Design, you can subdivide linear or planar elements using reference objects (i.e., other linear elements, lines, etc.). The reference objects' axes must intersect the axis of the element to subdivide.
Linear elements can be divided into a specified number of segments of equal lengths.
CAD Modifications toolbar: click
.
Keyboard: press <CTRL + B>.
Select a linear element.
Access the command.
Select the object(s) to subdivide.
On the command line, enter a value representing the number of linear elements to obtain (e.g., 3) and press <Enter>.
The linear element is divided by the input value.

Subdivide a linear element into a specified number of segments
Select an object intersecting the element to subdivide.
Access the command (notice the command line message).
Click the element to subdivide.
The element is divided by each intersection with the reference element; each subdivision becomes a whole entity.

Notes
The cut limits are set by the OXY plane created by the planar elements' axes or by the OXZ plane created by the linear elements' axes. If the reference object does not intercept the element to cut, the cut plane is virtually extended to this element's axis.
Several reference objects can be selected at the same time.
