You can configure the Modeling Toolbar for each model type separately.
● You can insert object symbols.
● You can restrict the object symbols displayed to the number you require.
You can only remove object symbols that are not used in the model. If you remove object symbols that are used in the model, the modeling toolbar will be split at the end. The object symbols that you have removed from the modeling toolbar but which are used in the model are listed underneath the separator bar. Object symbols that are placed below the separator bar will automatically be removed as soon as the last object with this symbol is deleted from the modeling area.
