Hello CADTech,
AutoPLANT reads class.ini whenever component insertion is made in AutoPLANT. Adding classes in Specgen enables to add the components on it. Also, defining criteria i.e. adding more fields helps narrow down to the requirement.
Please note "Where clause" is read from speckey.ini file as a search criteria.
A dialog like below Ex: "flange selection" will be shown which helps to select the appropriate component.
