Having trouble with recalculate when editing revolution roughing tool-paths.

1. Setting the 4th axis and cutting region.
2. Tool-paths created with Four-axis 3D Tool-path Roughing.
3. Recalculate the Revolution Roughing tool-path. The dimensions of the cutting region are automatically reset to the stock model before the process re-calculates, which leads to an error.
