CALCMOI,<normalx>,<normaly>,<normalz>,<rightx>,<righty>,<rightz>,<sysno>
calculates the second moment of area for the current active model
normalx – x of the normal of the original cut plane in global coordinated
normaly – y of the normal of the original cut plane in global coordinated
normalz – z of the normal of the original cut plane in global coordinated
rightx – x of the local right in global coordinates
righty – y of the local right in global coordinates
rightz – z of the local right in global coordinates
sysno – the system number where the local system will be stored
