There should be clear boundaries between different format specifications: a specification for 3D topology objects (constrained and unconstrained), a specification for 2D objects (constrained and unconstrained), a specification for technical drawing objects (multiple specifications each tailored to a specific type of drawing), a specification for BIM, a specification for FEM, etc.ĭevelopment platform vs User-ready bundles It's a mashup of multiple tools and addons without a consistent vision. There should be a difference between objects that are shareable pieces (local coordinate system), objects that exists in a 3D space (global coordinate system), objects that exists on paper (2D coordinate system with scale) and objects that don't exist neither on paper nor in 3D (references, labels, descriptions, databases, materials)įreeCAD lacks any sort of file format specification. There's no clear separation between different groups of objects. Make a clear separation between user facing UI/forum/documentation and the development one. Handle the toponaming issue or at least warn the user when it surfaces Not be religious about the parametric approach.
