Reattach Sketches

A sketch can be reattached to a different planar face, datum, path, or even a different orientation. This change can be a powerful command when the positioning of a feature needs to be moved. Of course, there are tools like synchronous modeling that can adapt features after creation, but adjusting the location of the sketch will properly fix the feature from its foundation.

The first step is to make sure the sketch is independent or only controlling the feature you want to adjust. If the sketch is internal to the feature, then the sketch will have to be made external within the model history.

When editing the sketch there are two options: Edit Parameters and Edit with Rollback.

Editing Parameters will allow for editing within the Direct Sketch.

Use the Direct Sketch group when you want to:

  • Create or edit a sketch in the Modeling, Shape Studio, or Sheet Metal applications
  • See the effect of sketch changes on the model in real-time

Editing with Rollback will allow for editing in the Sketch Task Environment

Use the Sketch Task Environment when you want to:

  • Edit an internal sketch
  • Experiment with sketch changes, but retain the option to discard all the changes
  • Create a sketch in other applications

In this situation we want to select Editing with Rollback.

The next step is to select the reattach button to engage in the original sketch plane selection dialogue.

In the reattach dialogue, the type of sketch(1), the method(2), the orientation(3), and the origin(4) can all be adjusted.

Now finish the sketch and make sure the rest of the model rebuilds correctly.

Editing the foundational sketch can sometimes have unwanted consequences on dependent features.

To easily jump around in the model history, consider using the feature replay resource. Enable the Feature Replay Group by choosing the Ribbon Options Drop-down arrow on the right of the Ribbon Bar. The Feature Replay functions are tools to step through the features used to create a model.

Enjoy!
