Scale

Scale resizes an object with precise control over dimensions, proportions, and unit conversion. You can scale uniformly, lock specific axes together, or resize each axis independently.

How to Use

  1. Select an object
  2. Click Scale in the Transform group of the toolbar
  3. Choose a Scale Type, then enter the sizes or percentages you want

You can also scale objects in the viewport by clicking and dragging the scale corner controls on a selected object.

Parameters

Scale Type

Choose your own size, or one of four unit conversions:

  • Custom (default) - Enter your own sizes or percentages. Choosing Custom after a unit conversion keeps the part at its current size, so you can adjust from there
  • Inches to mm - Makes the part 25.4 times bigger: for a model drawn in inches that came in too small
  • mm to Inches - Divides the size by 25.4
  • mm to cm - Makes the part a tenth the size
  • cm to mm - Makes the part 10 times bigger

Undoing a Scale Type change gives the part back the size it had before. This works the same on every Scale, including those in designs saved by earlier versions.

With a conversion chosen, the panel shows the resulting Width Percent, Depth Percent and Height Percent as read-only values, and the rows below are hidden.

Scale Method (Custom only)

  • Direct (default) - Enter the Width, Depth and Height you want, in mm
  • Percentage - Enter Width Percent, Depth Percent and Height Percent of the original size

Lock Proportion (Custom only)

  • None - Scale freely: each axis changes on its own
  • X Y - Width and Depth stay locked together; Height changes on its own
  • X Y Z (default) - Width, Depth and Height all change together, keeping the part’s proportions

Dimensions

  • Width - Size along the X axis
  • Depth - Size along the Y axis
  • Height - Size along the Z axis

Tips

  • Use “Inches to mm” if you imported an STL file that was designed in inches and appears too small
  • With Lock Proportion on X Y Z, changing any one dimension updates them all
  • The object’s base position is maintained during scaling so it stays on the workspace surface
  • You can type exact values for precise sizing, or use the sliders for quick adjustments
