# HOOPS Communicator 2021

HOOPS Communicator 2021 is based on HOOPS Visualize 2021, HOOPS Exchange 2021, and HOOPS Publish 2021.

## Enhancements

New Measure Operators

- Area of a polygon on a plane
- Angle between two lines
- Total distance of a polyline
- Distance between two points

Reduced file size from DWG conversions. Text outlines are now rendered in the Web Viewer, rather than stored in the Stream Cache file after conversion. This results in a smaller Stream Cache file.

New performance flag added to Converter. A new flag has been added to Converter named `--sc_editable` with a default value of `False`. If set to `True`, two copies of the mesh data will be generated: one for streaming and another for editing. In previous versions, this was the default behavior.

Only set this flag to `True` if you intend to edit the mesh data.

3MF Import and version 2.0 now supported. HOOPS Communicator 2021 now supports 3MF formats up to version 2.0 and can read (Import) the file format in addition to write (Export).
