I work with the latest versions of 2D and 3D CAD systems, if necessary I have the conversion tools to import and export patterns to and from other well-known systems such as Geminicad, Assyst, Gerber, Lectra, Investronica etc.
Because sustainability is important to me, I prefer to supply the patterns as much as possible digitally. Plotting of course can also, this happens always on recycled paper.
Via the "virtual fitting" of the 3D pattern on a avatar, you can skip various passes of sample making, resulting in time savings and less material consumption.
In fact, my complete business operation runs on 100% of renewable energy produced by our own solarpanels.
