Save Geometry is an effect for use with Chisel 2.0 or later that converts the contents of a Marathon 2 or Infinity map to a Geometry file. It is a great way to copy elements between maps.

Geometry Files

The Geometry File format is a simple list of interconnected points in text format. There should be a detailed description of the format accompanying this effect. It is designed to be a simple interchange format between PICT, DXF etc and the Place Geometry effect. Why not read PICT and other formats directly? Every application seems to write PICT and DXF differently. Some generate huge numbers of lines, others masses of proprietary tags. The image is in there somewhere, but you can't easily open up the format to edit it. Geometry is text based to allow this. Using Geometry files also allows other people to write converters for their favourite format, or script their application to dump out a drawing as a Geometry file. Supplied with this effect is its sister, Place Geometry, which will place the geometry file you make into another map, and v1.0 of MakeGeometry which can convert PICT files. In the future the MakeGeometry program will also be able to convert DXF files as well as optimise Geometry files for more compact storage.
