Compound Paths in the 8.2.1 Update
In this tutorial I show how changes in 8.2.1 make for a much better experience when working with bezier data brought in from Adobe Illustrator which has compound paths. The updated handling of this data makes for easier modeling and can help improve render performance (polygons render faster than bezier structures generally). In general it’s better to use the Thickness function when giving imported bezier profiles thickness instead of the bezier extrude tool when render performance is important. This is because polygon data is faster to render than complex bezier regions and this tutorial demonstrates this.
