User Overrides

Overrides can approximate the setup of an ISOGEN .DDF file.  Using the following rules the iso output will mimic the look of a defult .DDF file.  The following sections from the .DDF do not translate to the overrides:

PIPELINE-ATTRIBUTES-DOTTED

There is no equivalent controls in the overrides.txt file.

FITTINGS-UNDIMENSIONED-BRANCHES

There is no equivalent controls in the overrides.txt file.

BEND/ELBOW-REPRESENTATION

Overrides.txt does not of the items in this section.  The symbols for bends and elbows would need to be edited in the .cell file.

MISC-ITEMS

Overrides.txt does not of the items in this section.  Edit the seed file to affect changes Dimension text, Dimension lines, etc…

LAYER-NAMES

Level Names are defined in each rule and will be generated if a rule is used.

DDF Rules

Add the following rules to the overrides.txt as discused in the following wikki or download the sample file here Sample Override file: How to User Overrides for Isometrics Components
