EVR - v14


evr                             <input_filename> <output_filename> {+} {MATTCHATT}

Function

This utility reads an Eagle PLO or PLX file with the purpose of cleaning it, optimizing the interaction with the device and also reducing the size of the final PLO or PLX file.

Description

This operation of this utility removes the redundant vectors and arcs from a plot file, also optimizing the order of data for faster plotting.   If requested, it also converts arc polylines into true arcs/circles.

The different features of this optimization are:
1. Remove redundant vectors, that are overlapping lines.
2. Remove redundant arcs, that are overlapping arcs.
3. Transform collinear vectors in one single vector.
4. Transform concentric arcs in one single arc.
5. Transform segments representing an approximated arc into the proper arc item.

Parameters

input_filename

the name of the plot file (default extension PLO) to optimize.

 

 

output_filename

the name of the resulting plot file.

 

 

+

 

Advanced algorithm for arc conversion, The default is the base algorithm, faster but less precise.
 

MATTCHATT

Enables the ability to avoid merging vectors or arcs with different layers or attributes. When this primer is specified, items are merged only if layer and user-defined attributes are coincident.

Examples

EVR Origin.plo Result.plo +
EVR Origin.plo Result.plo

EVR Origin.plo Result.plo MATCHATT

EVR Origin.plo Result.plo + + MATCHATT

Notes

EVR  enables handling of the new PLX format that includes attribute definition for items (ref. #4917).  The new PLX format is obtained from the DUMP command with the SET PLOT=ETCH option enabled.

 

The latest evr.exe utility version is V12.3a aligned to Eagle V14 and compatible with new PLX files.
