Update Truss Shapes

This function can be used to reselect the structures limiting the trusses in the existing truss area from above and below. You can select the limiting structures like when adding a truss area, see Add a Truss Area and Truss Volumes. You can confirm the old selections right away by selecting the Confirm function.

You can edit the selections by clicking the structures selected during the adding phase so that they are deselected, or by selecting new structures.

Before you accept the upper and lower limiting structures with the Confirm function, you can select the auxiliary function Edit slope reference data from the contextual toolbar. With this function, you can determine the distance between the top or bottom chord of the truss and the limiting structure.
