XS_MAXIMUM_NUMBER_OF_PLANES_TO_NAME
Category in Advanced options dialog box
Modeling Properties
Use to define how many planes Tekla Structures names when the planes are used, for example, in defining distance variables. The default value is 400.
When the maximum number of planes is reached, Tekla Structures stops naming the planes and uses the name Undefined plane for the rest of the planes.
This advanced option is model specific and the setting is saved in the options database.
