### Master Data

For each part master data may be created. These data are filed under variables and saved for the respective part.
The variables of master data are created automatically upon request (icon in window Part-Info). You may put in or modify the corresponding data via input mask at any time. The number, kind and name of the master data which can be created automatically within the parts, are determined via stammd.sys file under the logical directory `$cadstl`. You may add data to this file or modify it.
Further you have the possibility to create additional variables of master data and save data with the command CREATE VARIABLE. Please take care that the name of the variable starts with a '&'.
For further information about and explanations of this topic please see the help text of the command CREATE PART. Please click the bill icon (symbolizes a shaft ) under the command CREATE PART with the right mouse button.
