Sketch menu: Scale tool

What is the Scale tool?

You can use the Scale tool to resize sketch items uniformly or non-uniformly around a chosen center point. Uniform scaling preserves proportions, while non-uniform scaling lets you adjust dimensions independently.

How to use the Scale tool

1. Go to Sketch > Scale.
   For other ways to access tools, visit Accessing tools.
2. Select the sketch items you want to scale.
3. Choose a scaling Type:
   • Uniform – Resize the selection proportionally in all directions.
   • Non-Uniform – Resize the selection independently along the available axes.
4. If needed, reposition the gizmo center to set the center point for scaling.
5. Optional: To scale a copy while keeping the original, turn on Copy . The Copy badge appears blue when selected.
6. Use the gizmo or its dimension labels to adjust the scale.
7. Optional: To adjust settings while the tool is active, select Scale again to open the parameter card.
8. To finish, select an empty area of the modeling space.

Parameter Card and History Settings

The Scale tool includes a parameter card for adjusting settings while the tool is active. Scaling sketch items does not create a separate Scale step in History. Instead, the changes are reflected in the existing Sketch step.

Adjust Scale parameters

While using Scale, select Scale again to open its parameter card and adjust the following:

• Type – Choose Uniform to scale proportionally or Non-Uniform to scale along individual axes.

To learn more about parameter cards, visit Parameter Cards.

History settings

Scaling sketch items does not create a separate Scale step in History. You can still reopen the existing Sketch step to review or modify its settings:

• Plane – Select Edit… or Select… to change the plane or face containing the sketch, then select Done.
• Projection – If applicable, select Edit… to modify existing projections in the sketch.

To learn more about editing modeling steps, visit History.

When to use the Scale tool

The Scale tool is useful for:

• Resizing sketch profiles – Make an existing profile larger or smaller without redrawing it.
• Creating size variations – Adjust a sketch design to fit different dimensions.
• Changing proportions – Stretch or compress sketch geometry along individual axes.
• Scaling around a reference point – Control how geometry expands or contracts relative to a chosen center.

Best practices and troubleshooting

• Use Uniform scaling when you need to preserve the original proportions.
• Move the gizmo center before scaling when the resize should be anchored to a particular location.
• Check existing sketch constraints and dimensions if the geometry does not resize as expected.
