◦ The string format is A x B x LG.
◦ The rotational symmetric part outline string is formatted as DM x LG.
◦ The gray box displays the volume of the bounding box.
◦ The number of digits is defined by the option NR_DIGITS_COMMON.
◦ The preview box shows the top and side projections on which the analysis result is based.
5. Use Convert outline result to to convert the result into INCH or MM.
6. Use Calculation Method to switch between calculation method.
◦ Best fit—Algorithm tries to detect whether component is cylindrical or cubical.
◦ Cubic—Outline is calculated for a cubical shape.
◦ Cylindrical—If a cylindrical shape was detected, the outline is calculated for the cylindrical shape.
7. Click OK to save the model outline as a parameter and close the dialog box, or click Cancel to close the dialog box without saving the results.
