The Scale Ruler application serves as a straightforward tool for displaying measurements across various units. However, users should be aware of the following limitations:

  • The precision of the displayed scales cannot be guaranteed.
  • Calibration and PPI (pixels per inch) values will revert to default settings when the model is modified.
  • It is advisable to set the PPI value only when the model has not been determined.
  • After altering the PPI value, it is essential to recalibrate the application.

How to Use:

Select Mode:

In an UNLOCKED state, users can choose their desired measurement unit, magnification ratio, and reduced scale, which will then be displayed on the ruler.

Free Mode:

In UNLOCK mode, dragging the screen allows the user to set a scale ranging from 1:1 to 1:100. Holding down the scale value opens a keyboard for manual entry of scale measurements. Users also have the option to lock the scale using a toggle switch. Note that advertisements may appear during the unlocking process, which will cease after making an in-app purchase.

  • "Initialize" button: Resets adjustments to a specified value while applying the change to the ruler display.

Caution: Calibration values will reset with any changes to the model.

PPI (Pixels per Inch) Setting:

If there is uncertainty regarding the model in use, it is recommended to verify its PPI value prior to setting it within the application. The steps include:

  • "OK" button: Saves and updates the entered PPI value on the ruler display.
  • "Initialize" button: Resets the PPI value to a predetermined measure and reflects this on the ruler.

Caution: The PPI value will be reset upon changing the model.
