Image RemovedIf SpinFire Ultimate 2D measurements are off because of incomplete CAD data or the wrong units were used to import, Calibrate Drawing gives users an easy way to make a quick measurement, indicate the length of the measurement so all future measurements for the workspace are calculated based on that calibration.

To calibrate a drawing

1. Open a 2D model.

2. Click Calibrate Drawing from th 2D toolbar.

3. You must make a measurement and tell SpinFire Ultimate what that value is. Choose a distance that is known.
   Select to measure between two points or measure the length of an edge.

4. Click PICK.

5. Select the two points or the edge.
   SpinFire Ultimate populates the Distance on paper field and Distance on drawing field with the measured distance.

6. Calibrate the measurement by changing one or more of the followng fields.

   1. Type of measurement
      Select between Direct, X-axis aligned, or Y-axis aligned.

      1. Direct - calibrates based on the actual measurement

      2. X-axis aligned - calibrates based on the x-axis delta

      3. Y-axis aligned - calibrates based on the x-axis delta

   2. Distance on drawing
      Change the value in the Distance on drawing field if known or change the units of the Distance on drawnig field.

   3. Calibration factor
      Change the calibration factor as a multplier of the measured distance. Use a value greater than 0 to multiply aganist the Distance on paper value.
      
      When APPLYis clicked, the Distance on drawing field shows the calibrated value.

7. Click APPLY or OK.

8. After the OK button is clicked, the Calbration Factor appears n th lower left corner of the screen.
