This dialog is used to maintain the relative position of two solids or two user-defined features.
You can constrain a solid to be a fixed distance from:
- another solid.
- a user-defined feature on another solid.
You can constrain a user-defined feature to be at a fixed distance from:
- Another user-defined feature that is in the solid tree.
- A solid that is not the parent of the user-defined feature being constrained.
- A user-defined feature on a solid that is not the parent of the user-defined feature being constrained.
Note: You cannot define circular constraints. The following constraints would not be valid:
Use the Solid and Feature drop-down lists to define the reference for the object to be constrained. The reference can be another solid or a user-defined feature on another solid. When scaling, the constrained object is scaled to maintain its distance from its reference object.
Solid - Select one of the available solids from the drop-down list.
Feature - Select one of the available features from the drop-down list.
Projection Axis
Use a projection axis to maintain distance - Click to use an axis of the workplane to maintain the distance. When this option is selected, modify the projection axis by changing the Origin, Axis and Twist options.
Select the projection plane - Select the axis from the drop-down list. The distance is maintained along the selected axis.
Axis - Click the button of the axis to be changed. Enter the axis information using the Direction dialog.
Twist - Click the button of the axis you wish to twist. Enter the twist value using the Calculator dialog.
Decide the best Stitching Margin automatically - If you want to keep the user-defined feature the same size, scaling produces a gap around the feature. A stitch margin stretches the portions of the solid around the user-defined feature to blend the gap generated around the feature, and maintain the closure of the solid.
If selected, PowerShape bases the size of the stitching margin on the size of the gap created.
If deselected, the Stitching Margin option is active.
Stitching Margin - Enter the distance around the periphery of the item being constrained, where stretching would occur when you scale the item. This option is only available if Decide the best Stitching Margin automatically is selected.
Unconstrain - Remove all the constraints on the selected item and close the dialog.
OK - Accept the constraints settings and close the dialog.
