Geodesic structure

A contemporary sketch model

Every number below is a modern illustrative assumption. The historical drawing supplies a question; the source model is an exercise in reasoning about it.

force = 2000 N in 1000..4000 "Assumed axial force from external load analysis"
area = 100 mm^2 "Assumed strut cross-sectional area"
allowable = 50 MPa "Illustrative material stress allowance"
stress := force/area [MPa]
margin := allowable/stress
check material: stress <= allowable
check marginBudget: margin >= 1.5
sweep Load: force = 1000, 2000, 4000 N

Model limits

Single-member axial stress only; not a dome stiffness solve, FEA, buckling check or code-compliant building design.

Explore it with your agent

Create a Study, inspect the installed capabilities, and use this source as a starting point. Ask the agent to explain the equations and assumptions, then replace illustrative inputs with measured evidence for your own design.

This example includes a scalar sweep. Use napkin_sketch to add the model and napkin_run to inspect the sweep; the source editor’s scalar comparison view is for simple scenarios.
