Stretches a manufacturing part to account for steel shrinkage during welding. Adding shrinkage changes the position of marks and openings on the part because they are stretched along with the part. The part shrinks back to its needed size and shape in the welding process.
For plate parts, you can define shrinkage in one or two directions as scaling shrinkage (defined by the expansion ratio and the expansion direction). For profiles, you can only apply scaling shrinkage to the length.
By default, the software prompts you to identify the edges so that it can determine the shrinkage directions. If you select the shrinkage type by global axis, the software sets the primary and secondary axis based on the plate type:
For deck plates, the primary factor is the X axis and the secondary factory is Y axis.
For transverse plates, the primary factor is the Y axis and the secondary factory is the Z axis.
For longitudinal plates, the primary factor is the X axis and the secondary factory is the Z axis.
A small coordinate system, based on the shrinkage directions with the appropriate values, also displays in the Part Monitor.
For built-up profiles, you can define the shrinkage for the web and flange separately.
Displays the controls used to add a shrinkage margin to plate edges or profile ends.
Activates the Shrinkage Properties dialog box, which you use to view and modify the properties of the shrinkage margin that you are about to place in the model. For more information, see Shrinkage Properties Dialog Box.
Plates or Profiles
Select the plate or profile part to which you want to add the shrinkage. You can select the part in a graphic view or in the Workspace Explorer.
Because of the different ways in which shrinkage is applied to plates and profiles, you can only select either plates or profiles.
Select a line to indicate the primary direction for the shrinkage. The primary direction vector is in the direction of the first selected plate lateral face.
Select a line to indicate the secondary direction for the shrinkage. The secondary direction vector is perpendicular to the primary direction vector unless another plate lateral face is selected.
Creates the shrinkage using the parameters that you have defined.
Select the mode of shrinkage to apply. The following options are available:
Assembly - Places global axis shrinkage on an assembly.
Part-Assembly Based - Places shrinkage on the parts of an assembly depending on the shrinkage of the assembly.
Part-Private - Places shrinkage on the parts.
Check the rule to get values of Shrinkage Type, directions (Primary and Secondary), and factors (Primary, Secondary, and Tertiary) from the rule for the selected part to place shrinkage.
Select the direction type of shrinkage to apply. If you select Global Axis as the Shrinkage Type, then you can select a grid system axis to define the shrinkage direction. If you select by edge, the software prompts you to select one of two edges so that it can determine the shrinkage directions.
Select a factor for the amount of extra material to apply in the tertiary direction.
Shows all the frame systems from the catalog rule in the range of the selected plate. This option is only visible when the Shrinkage Type is Global Axis.
Select an axis corresponding to the frame system selected in the Frame System select list to represent the Primary Direction. This axis can also be picked in the Primary Direction step. This option is only visible when the Shrinkage Type is Global Axis.
Select an axis corresponding to the frame system selected in the Frame System select list to represent the Secondary Direction. This axis can also be picked in the Secondary Direction step. This option is only visible when the Shrinkage Type is Global Axis.
Select a factor for the amount of extra material to apply in the primary direction.
Select a factor for the amount of extra material to apply in the secondary direction.
The units displayed in the primary and secondary factor fields are determined by the Slope setting on the Units of Measure tab of the Options dialog box. Click Tools > Options to display this dialog box.
If no shrinkage is needed in the secondary direction, use a Secondary Factor of 1.00.
