To sketch beams using the Chain option
1 Click Home tab
2 On the Options Bar, select Chain.
3 Place the first beam in the chain. See
4 Place each additional beams by clicking the endpoints of the beams.

Sloped Beam Modeling

If your project contains complex sloped members for which you need to add beams, you can match beams
to uneven columns, roofs, structural floors, or walls using the following procedure.
To adjust sloped beams
1 Select a beam that is connected to 2 structural members or warped model objects at different
2 Click Modify Structural Framing tab
3 In the Instance Properties dialog, enter a value for the Start Level Offset instance parameter of
4 Enter a value for the End Level Offset instance parameter of the beam, and click OK.
5 Verify that you have entered the correct offset values.

3D Snapping

You can use the 3D Snapping option to create a new beam by snapping to other structural elements in any
view. This means that you can sketch beams and braces outside of the current work plane. For example,
when 3D snapping is enabled, roof beams will snap to the tops of columns, regardless of elevation.

Example of sloped beam modelling.
NOTE A beam that has adjusted offset values will become disassociated or free from the current work
plane. Similarly, any structural element attached to a sloped beam will also become free. You attach
free elements to another work plane using the existing Edit Work Plane or Rehost buttons on the
Work Plane panel of the Modify Structural Framing tab.
