About Curved Structural Members
The smoothness (tessellation) of curved edges is controlled by the FACETDEV variable. This variable sets the number
of facets to display on curved AEC objects. The default value is 1/2'' for drawings created from imperial templates and
is 12.7 mm for drawings created from metric templates.
The number you specify for facet deviation defines the maximum distance from the chord to the arc—the chord being
an edge that is created from faceting the curve to the true mathematical arc. The facet deviation has a range of greater
than zero (0) and no upper limit.
The minimum number of facets is 8. For example, if you create a cylinder mass element to have a 1' radius, and specify
1' for FACETDEV, the cylinder has 8 faces.
The plan representation of individual curved components of columns uses the true curved representation of the member
shapes. The above and below cut components will always be faceted.
The maximum number of facets is controlled by the FACETMAX variable. This variable can be set from 100 to 10,000.
Note that using a small value for FACETDEV and a large value for FACETMAX will adversely affect drawing performance.
To specify the facet deviation values for the current drawing, see “
Specifying the Display Resolution of Objects with
Facets
” on page 118. The settings apply to all curved objects in the drawing, including curved structural members.
Changing the Structural Member Justification
Use this procedure to change the justification of a structural member. Justification positions the shape of a structural
member in relation to its extruded axis. Changing the justification of an existing member moves the member and can
affect how the member relates to other objects, such as how a column is positioned in relation to a column grid when
it is anchored to the grid.
Justification options for a beam
You can also specify the justification of structural members with multiple shapes and segments. For more information
about these members, see “
Creating Custom Structural Members
” on page 1436.
1
Select the structural member to change, and double-click it.
2
On the Properties palette, expand Basic, and expand Dimensions.
