In O-Calc Pro version 5.03, an additional plugin became available for use. This plugin, available from the plugins download website, allows a user incorporate an existing .pplx file into the .pplx file of another pole, as an additional version.
First, ensure that this plugin has been downloaded/installed, per the Installing Additional Plugins in O-Calc Pro YouTube video or wiki page.
Once this plugin is enabled, model your pole as normal.
To utilize this plugin, navigate to the File drop-down menu and select Add New Pole as Version, which can be found right below the list of previously opened poles.
