The graphic help defines all the modifiable parameters. Some of the parameters are of geometrical type (screw diameter) and some of functional type (tapping depth). You may scroll a leading parameter (D1 in this case) defining the standard components from the catalogue. If you key-in for the leading parameter data which exists in the catalogue it will also be recognized and all the standard parameters will be retrieved. You may select a standard component by catalogue number from the Catalogue box. You may type in alphanumeric data thereby creating non-standard components.

The parameters in this button define the clearance dimensions for the screw holes. D1 = 0.5 means that the diameter of the hole for the screw will be 0.5mm larger then the nominal dimension of the screw. D2 = 0.5 means that the diameter of the hole for the screw head will be 0.5mm larger the nominal diameter of the screw head. You can change the default clearance dimension and click the Save button to save the new values as defaults for subsequent sessions. The save button is disabled as a default. It is strongly recommended that only a system administrator will enable this button. In order to enable the save button type (moldbase-ui::setadmin t) in the Enter Command Line. In order to disable it again type (moldbase-ui::setadmin nil)

The system creates all the relevant holes, with defined clearance dimensions, in Plate3 and in the core insert in one step. Notice that the counter bores for the screw heads were deepened in order to fix the problem of the "short" screw selection.
