ESA Motion
Engineering software, made practical

Design. Calculate. Automate.

ESA Motion is a growing collection of practical engineering tools for makers, fabricators, designers, and engineers — built to turn 3D concepts into things you can actually build.

From reference geometry to fabrication data.

FrameDesigner combines interactive 3D frame design with fabrication-aware geometry, automatic joint calculations, bend data, notch visualization, measurements, and manufacturing output.

Reference geometry
3D reference geometry

Work around imported 3D models

Load multiple STL, OBJ, GLTF, and GLB-style reference models. Position, rotate, scale, hide, and inspect them independently while the frame remains dimensionally separate.

Frame design
Tubular frame design

Round, square & rectangular tube

Create members joint-to-joint, move and split tubes, add multi-bend geometry, apply symmetry, select standard or custom tube sizes, and control profile clocking.

Joint intelligence
Automatic joint and notch calculation

Automatic notch calculation

Physical joints are discovered from geometry and recalculated as the structure changes, including miter, cope, terminal, multi-contact, straight-host, and compound bent-host conditions.

Fabrication
Tube fabrication specifications

Tube-by-tube build specifications

Review stock length, chord length, fabrication order, bend sequence, bend CLR and angle, end-cut operations, developed length, and per-cut tolerance for each member.

Visualization
Interactive fabrication preview

Interactive fabrication preview

Inspect the selected tube in an orthographic 3D preview with neighboring members, raw-stock extensions, bend highlights, notch contours, and unfolded Notch 1 / Notch 2 views.

Output
FrameDesigner export and output

Export the design for the next step

Generate fabrication PDFs and export frame geometry through JSON, STL, OBJ, and STEP-related solid-CAD workflows, including straight and bent members with notch reconstruction.

Engineering tools for people who build.

Each ESA Motion application is focused on a real design or fabrication workflow. FrameDesigner starts with tubular frame design, and the platform will expand with more tools for mechanical design, calculation, simulation, and automation.

FrameDesigner

Import 3D references and create fabrication-aware tubular frames with joints, bends, profiles, notches, measurements, and export tools.

Automation

Utilities that connect calculations, engineering data, repetitive workflows, and machine-ready output.

In development
An Esacode platform

Software for engineers, makers, and fabricators.

ESA Motion is developed by Esacode, LLC. The goal is straightforward: create modern engineering software that is fast to access, easy to understand, and useful from the first minute — especially for builders who need practical design and fabrication tools without heavyweight CAD workflows.
