Scale (R3SCALE)

Command: R3SCALE

Scales selected entities from one unit to another. Use this when geometry has been drawn or imported in the wrong units and needs to be converted to match the rest of the drawing.

Usage

1. Type R3SCALE or click Scale in the ribbon
2. Select the objects to scale
3. Pick a base point
4. Choose the from unit (what the geometry is currently in)
5. Choose the to unit (what it should be)

R3SCALE calculates the scale factor automatically and applies it.

Example

Geometry drawn in international feet needs to be converted to metres:

• From: Feet
• To: Metres
• Scale factor applied: 0.3048

Notes

• The original entities are scaled in place — there is no copy made
• Use UNDO (Ctrl+Z) to reverse if the wrong units were selected
• This command is equivalent to using SCALE with a manually calculated conversion factor, but without the arithmetic
