Macro Convert 021

Description

This macro opens a file dialog to allow to choose a FreeCAD file and converts it to 0.21 format (replace AttachmentSupport property to Support). A new file with extension .021.FCStd is created so the original file is not modified.

Usage

Run the macro and select a FCStd file when the dialog pops up.

Install

Through Addon manager.
