Editing Trusses

Trusses can be selected like other objects in Chief Architect. See "Selecting Objects" for more information.

Once selected, trusses can be edited using dimensions, their edit handles, the edit toolbar buttons, or by opening them for specification.

Trusses can be deleted all at once in the Delete Objects dialog. See "Delete Objects Dialog".

Using Dimensions

Using the Edit Handles

When a truss is moved, its shape updates to conform to the roof and ceiling plane positions in its new location.

If a truss has been locked, the size does not update if the truss is moved, but maintains its original settings. See "Roof Truss Specification Dialog".

The width and depth of truss chords can be changed in the truss's specification dialog, but not using the edit handles.

If drawn along an exterior wall, it snaps so that its outer surface is flush with the outer surface of the wall's main layer.

The center line can snap to the edge or corner of a nearby roof plane. To prevent this, zoom in closer while moving it or toggle Object Snaps off.

Like joists or rafters, trusses can be selected and moved in 3D views. The only difference is that the Lock Truss and Webbing setting in the Roof Truss Specification dialog prevents the truss from moving back to between the roof and ceiling planes the next time it is edited or otherwise changed.

Using the Edit Toolbar

A selected truss can be edited in a variety of ways using the buttons on the edit toolbar. As with most objects, trusses can be copied, replicated, moved, and deleted. See "Using the Edit Toolbar".

The following edit buttons may display on the edit toolbar for selected trusses.

Click the Select Next Object

button to select nearby objects instead of the selected door, particularly the wall it is placed in.

Click the Open Object

edit button to open the truss for specification. the truss specification dialogs are covered at the end of this chapter.

In floor plan view, an individual truss or a selected group of trusses that are all parallel to each other can be moved the proper distance from a framing reference marker using the Move to Framing Ref

edit button. See "Framing Reference Markers".

Copying Trusses

When a truss has been edited to suit your needs, use the Multiple Copy edit tool to create duplicates at specified intervals. The copies conform to the roof and ceiling plane positions in their new location.

To use Multiple Copy

Select the truss to be copied in floor plan view.

Click the Multiple Copy edit button.

Click the Multiple Copy edit button again to open the Multiple Copy dialog. See "Multiple Copy".

Enter the correct spacing in the All Trusses box. Once set, click OK.

Select the truss and use the Move edit handle to drag it perpendicularly. The pointer becomes a four-headed arrow

when it is over the Move handle.

New trusses appear as you drag. Drag as far as necessary to produce all desired trusses. Each truss is created according to the particular Roof/Ceiling/Truss Base planes above and below it.

If copied trusses become different from the original as a result of the roof/ceiling planes around them, their labels are different from that of the original. See "Truss Labels".
