AutoCAD - Use A Different Scale For X, Y & Z

AutoCAD provides a SCALE command that can be useful when we want to scale a drawing by a constant factor. On some occasions, we may want to use a different factor for each axis. A typical example is when we have a model where the dimensions in the plan are in millimetres but the elevations are specified in metres, and we want to convert it to metres for all three axes.

The following simple workflow will help us achieve that goal:

  • Select the entities that you want to scale and type BLOCK in the command line to convert them into a block.
  • Give it a name and select all the relevant options, making sure that Scale uniformly remains un-ticked.

  • Press Ctrl + 1 if the AutoCAD PROPERTIES palette is not showing, and select the newly created block.
  • In the Geometry section of the block properties, change the fields Scale X, Scale Y and Scale Z to the values you require:

The block will automatically update to the scale factors that have been selected. If you don’t want it to stay as a block, you can just select it and type X in the command line. That will explode the block and the original entities will come back to the drawing, now scaled with the factors previously selected.
