Release of ezdxf v1.3.0

[mozman]

Release v1.3.0

• Changelog: Version 1.3.0 - 2024-05-01

• New output backends for the drawing add-on

  • GeoJSONBackend
    • Creates a JSON-like output according the GeoJSON scheme.
    • All DXF entities are resolved into lines, polylines and polygons.
    • Curved shapes are flattened to polylines and polygons.
    • The properties are handled as a foreign member features.
  • CustomJSONBackend
    • Creates a JSON-like output with a custom JSON scheme.
    • All DXF entities are resolved into lines, polylines and polygons.
    • This scheme supports curved shapes by a SVG-path like structure and coordinates are not limited in any way.
    • This backend can be used to send geometries from a web-backend to a frontend.

• Selection Tools

  • The ezdxf.select module provides entity selection capabilities, allowing users to select entities based on various shapes such as windows, points, circles, polygons, and fences.
  • The selection functions bbox_inside() and bbox_outside() work similarly to the inside and outside selection tools in CAD applications but the selection is based on the bounding box of the DXF entities rather than their actual geometry.
  • The bbox_overlap() function works similarly to crossing selection in CAD applications.
    • Entities that are outside the selection shape but whose bounding box overlapps the
      selection shape are included in the selection.
    • This is not the case with crossing selection in CAD applications.
  • The selection functions accept any iterable of DXF entities as input and return an EntityQuery container, that provides further selection tools based on entity type and DXF attributes.
  • Tutorial

• New ezdxf.revcloud module

  • The new ezdxf.revcloud module can render revision clouds similar to the REVCLOUD command in CAD applications.
    • 

• New features for ACIS based entities

  • Support for copying of ACIS based entities
    • This adds support for loading these entities by the ezdxf.xref module
  • Support for transformation of ACIS based entities
    • The transformation is stored as temporary transformation and will be applied automatically before export.
    • The applied transformation is a transformed anonymous block that contains that ACIS entity.
