When a beam is modeled, it is by default created horizontally at the top of the active storey in view.  <\/span><\/p>\n

The elevation of the beam can be changed using the <\/span>del z<\/span><\/b> boxes for each end of the beam in the <\/span>Beam Properties<\/span><\/strong> > <\/span>3D <\/span><\/strong>tab.<\/span><\/p>\n

Method 1 :  Input delZ manually in Beam Properties<\/span>
<\/h2>\n

With reference to the table top model below, when a beam is created <\/span>delZ \u2013 I<\/span><\/strong> (left end) and <\/span>delZ -J<\/span><\/strong>
\n (right end) defaults to 0.  Hence the top of the beam is in the same
\nhorizontal plane as the top of the storey (which is also the default top
\n of slab).<\/span><\/p>\n

<\/p>\n

A positive value of <\/span>delZ<\/span><\/strong> will raise the beam end while a negative value will lower it.  <\/span><\/p>\n

For
\n example, if delZ- I = 500 and del Z -J = -1000, the left end will be
\nraised 500mm and the right hand will be lowered by 1000mm.<\/span><\/p>\n

<\/div>\n

Looking
\n at the 3D physical model, it is not entirely clear if the left end of
\nthe beam is still connected to the column. The only way to verify the
\nconnectivity of members is to run <\/span>Building Analysis<\/span><\/strong> and then go to the <\/span>Analytical Model<\/a> <\/span><\/strong>to investigate the analytical model (as shown below).<\/span><\/p>\n

<\/p>\n

As shown above, the analysis automatically extended the height of the column by creating a<\/span> <\/span>rigid link<\/span> <\/span><\/strong>(dark
\n blue line). This is because the depth of the beam is 500mm and the beam
\n end is raised by 500mm, hence the bottom of the beam end technical
\nstill meet the top of the column. Hence, the analysis intelligently
\ncreated this rigid link to connect the column and beam.<\/span><\/p>\n

Alternatively, if in doubt, you can raise the top of the column by the same value by using the <\/span>delZ \u2013 top<\/span><\/strong> box in the column properties (as shown below).<\/span><\/p>\n

<\/p>\n

Method 2 : Using insertion points in the 3D view
<\/span><\/h2>\n

It is also possible to create a slanting beam by clicking on the smart points along the column length in the 3D view :
<\/span><\/p>\n

    \n
  1. With the beam properties out, hover the mouse cursor along the column.<\/span><\/li>\n
  2. Select \/ Input the 1<\/span>st<\/span><\/sup> end of the beam using any of these methods<\/span><\/li>\n<\/ol>\n
