Element Modification - Shapes tab

SettingDescription
Shorten In all three Shorten modes, you must pick the shape near its end point for it to be modified. If you pick in the middle third of the shape length, each end is shortened by half the specified value.
  • - Shortens a shape by picking two points. The perpendicular distances to the shape centerline specifies the shortening amount.
  • - Shortens a shape by explicitly indicating the value.
  • - Shortens the shape by the value entered in the Default option.
  • Default - Provides a default value for the Shorten methods.
Lengthen These functions can be used analogously to shape shortening in order to extend a shape.
  • - Lengthens a shape by picking two points. The perpendicular distances to the shape centerline specifies the lengthening amount.
  • - Lengthens a shape by explicitly indicating the value.
  • - Lengthens the shape by the value entered in the Default option.
  • Default - Provides a default value for the Lengthen methods.
Warning: Shape ends modified by a cut can not be lengthened.
Creates a parametric notch (cope) on a shape where it intersects with another shape. When you select a shape pair, the Cope dialog opens.
Creates a notch (cope) on a shape manually. When you select a shape and the end to cope, the Cope dialog opens to the Shape End tab.
Miter cuts
  • - Combines two shapes by means of a mitred cut, which can also be carried out as 3D-cut. A bisecting line determines the cutting plane. If the height of the two shapes differs, the outer edges are not aligned.
  • - Combines two shapes by means of a mitred cut. The intersection points of outer and inner edges determine the cutting plane. This means that even shapes of different height are correctly cut aligned.
  • - Combines two shapes with an arc element of the shape type picked first that is inserted with the specified Radius value.
  • Don't lengthen shapes - When on, the miter cuts performed on shapes that do not intersect are only applied to the first shape selected. The second shape is not lengthened or mitred.
  • Radius - Specifies the radius of the arc element to be inserted when using the miter cut. The this radius can either be entered as absolute value or as many times the maximum diameter of the first shape.
  • Gap - Specifies a gap to be maintained between the shapes at the miter cuts.
Note: A logical link is created between the parts at these cutting commands. The result will be that if one part is modified, the cut will be automatically updated.

Miter Cut Examples

Some examples of miter cuts created using different methods:

Same shape sizes (top row), Different shape sizes (bottom row)

  1. Bisector
  2. Bisector with gap
  3. Inserted arc segment
  4. Bisector different shapes

Modify Connections of Structural Steel Work

With Element modification, you can also modify connections using the (Edit Connections) tool on the Connection Editor tab to open the corresponding dialog.
