In Advance Design, the chained linear element function creates end-to-end linear elements. The position of the element extremities can be specified by entering the coordinates of each extremity in the command line or by snapping to other objects.
Below you can find the various methods to access the command:
From the Menu: select Generate > Structure > Linear > Chained linear element.
From the Modeling toolbar: click
(click and hold
dropdown list).
From the Ribbon > Home tab > Linear & Planar panel > Linear section dropdown list > select Chained Linear Element.
From the Project Browser: right click a system and select Generate an entity > Structure > Linear > Chained linear element.
