The distribution environment may be operable to access a CAD model associated with geometry and generate a tessellated model including geometric object(s) that establish a tessellation of the geometry. The geometric object(s) may be operable to display the tessellation in a viewing window of a user interface according to views associated with respective view identifiers. Each of the views may be associated with a respective depiction of the geometric object(s) in the user interface. The distribution environment may be operable to determine transaction parameter(s) associated with a smart contract. The transaction parameter(s) may include a view access parameter specifying one or more of the view identifiers. A method of distribution for a tessellated model is also disclosed. ## Claims ### Claim 1 A system for distributing a tessellated model comprising: one or more processors coupled to memory; wherein the one or more processors are collectively operable to execute a distribution environment, and the distribution environment is operable to: access a computer-aided design (CAD) model associated with geometry;
