The detail that caught me off guard is the maker's claim that the whole process takes only a few clicks. A woven 3D relief sounds like heavy modelling work, yet the tutorial presents it as a short, routine sequence.
It begins with vector preparation in 2D CAD. The relief profiles are two sine wave lines set out of phase with each other. The toolpath vectors are evenly spaced horizontal lines with short vertical ticks, and vertical drive rails cross those horizontal lines in the arranged geometry. Once the geometry is imported into the CAM environment, the Extrude and Weave function is opened: the vertical drive rails are selected, then the wave profile, and that generates a woven 3D mesh. The horizontal lines are then picked to serve as the cutter toolpaths. A Profile Toolpath is set up with a cutter matching the relief width, and the option to project the toolpath onto the 3D model is switched on. A 3D simulation shows an end mill running along each horizontal trajectory while conforming to the relief, and from there the toolpath is ready for machining.
The tutorial opens and closes on the physical result: a prototype panel machined from MDF carrying an undulating, woven ribbon texture.
Some context worth having: the maker spent many years in ArtCAM and only recently began learning Aspire. Aspire felt easy after ArtCAM because the principles are very similar, though ArtCAM still seems simpler to them. This was also a first attempt at this kind of operation in Aspire, worked out intuitively while going along. One loose end remains: Aspire was left out of the post title, and that title can no longer be corrected.
