Requirements and load paths
Confirm the job, trace real forces to their supports, and orient profiles for the critical direction.
Free modular frame design tool
Find the weak assumptions before they become expensive aluminum.
A practical 10-point review for engineers, machine builders, labs, and integrators designing extrusion frames, guards, carts, fixtures, and test stands.
- Fillable and printable PDF
- Two-minute first pass
- Vendor-neutral guidance
Preliminary review
10 checks
- 01 Requirements written down
- 02 Load paths identified
- 03 Critical deflection checked
- 04 Racking controlled
Expose risk before detailed CAD
Long unsupported spans
Moment-loaded joints
Uncontrolled racking
Manual BOM errors
What it catches
Ten questions that force the design to explain itself.
Stiffness and stability
Review span, deflection, joint demand, racking control, base conditions, and tip risk.
Interfaces and execution
Protect clearances, simplify assembly, and make sure the model, cut list, and purchasing BOM agree.
The output
A fast go, revise, or pause decision.
This is not a substitute for engineering calculations or a guarding and code review. It is a structured first pass that shows where deeper work belongs.
