Block limits

The Limits area specifies the physical extents of the block. You can lock specific X, Y or Z limits (Max, Min or Length) to prevent the value/s from being changed whilst adjusting the model limits.

• Unlocked — When displayed, you can edit the value.
• Locked — When displayed, you cannot edit the value. If you try to re-calculate the Block Limits by entering a specific or Expansion value, the Locked values remain unchanged.

  Click the button to toggle between Locked and Unlocked .
