Changing a Sketch Support

You can change the position of a sketch by changing its support. Changing a sketch support amounts to editing the absolute axis definition of the sketch.

In this scenario, you will edit the absolute axis definition of Pocket.2/Sketch.3 by making it associative to Pocket.1. This will ensure that, when moving Pocket.1, Pocket.2 follows Pocket.1 without requiring you to edit the geometry of Sketch.3.

About Changing Sketch Supports
  1. From the tree, right-click Sketch.3, and select Sketch.3 object > Change Sketch Support.


    Important: If a message appears, informing you that if you change its position, the sketch may become inconsistent or over-constrained, simply click OK. The Sketch Positioning dialog box appears.
  2. If Move geometry at the bottom of this dialog box is selected, clear it. This will prevent the geometry from moving when performing the next operations in the dialog box.
  3. Select Positioned in the Type box. This positions the sketch using the origin and orientation of the absolute axis.
  4. Make sure Pad.1/Face is selected as the reference element for the sketch support (Reference box).
  5. At this point, select Move geometry to specify that, from now on, the geometry should be moved when the sketch position is modified.
  6. Select Swap to swap H and V directions. The new sketch position is previewed in the work area.


  7. You are now going to make the absolute axis associative with Pocket.1. Clear Move geometry once again to ensure that the geometry does not move according to the newly defined axis.
  8. In the Type box in the Origin area, select Intersection 2 lines.
  9. You will now specify the reference element for the origin. To do this, make sure the Reference box is active, and select a horizontal edge of Pocket.1 as shown below.


  10. Now, select a vertical edge of Pocket.1 as shown below.


  11. In the Orientation areas, leave the Type box set to Implicit and the Reference box set to No Selection.
  12. Click OK.
    The absolute axis definition of Sketch.3 is modified and the position of the pocket is changed.



  13. From the tree, double-click Sketch.2 to edit it.
  14. On the sketch, double-click the offset value as shown:


  15. In the Constraint Definition dialog box which is displayed, enter a new value, 55 for example, and click OK.

    The constraint is updated, and Sketch.2 is moved accordingly.

  16. Exit the Sketcher app.

    As you can see, Pocket.1 has been moved, and Pocket.2 is still positioned according to the absolute axis you defined for Sketch.3.
