3DPrinting
3DPrinting is a place where makers of all skill levels and walks of life can learn about and discuss 3D printing and development of 3D printed parts and devices.
The r/functionalprint community is now located at: !functionalprint@kbin.social or !functionalprint@fedia.io
There are CAD communities available at: !cad@lemmy.world or !freecad@lemmy.ml

TNI is not about planes. It is about the linearity of the tree, the truncation of infinite numbers, and the loops the tree must patch on in order to break a linear branch of the tree. These breaks create a cascade of problems that are not possible to address because the information required is missing once the initial reference is created and truncated at the register level. It is not a single reference issue. All references down tree are relative and themselves often truncated. Breaking the tree is always the wrong thing to do. Yes it can be done as a hack to do something quickly, but that is just a hack. Stacking hacks is terrible design. This is the difference between a good designer and the bad. It is all about a linear tree and π.
I can design without any reference planes and just offsetting my sketches. I never use faces or import 3d geometry. I am very intentional about what references I import and those I do not. I also make some sketches as references only, and these are used to alter other sketches down tree. All of this is TNI centric.
