DYNMECH MOTION
From a STEP file to a moving machine — without writing a line of code.
Import your CAD assembly, choreograph S-curve velocities, signal handshakes and collision responses with logic blocks, and export a 3D animation your customer can watch by scanning a QR code.
The machine on the right is a live Motion demo — drag it around.
WINDOWS · MACOS — NO SOLIDWORKS SEAT REQUIRED
What does making a machine demo animation feel like today?
A DAY WITHOUT MOTION
- Buy a full premium 3D CAD suite — five figures a year — just for its motion module
- Hand-keyframe in a rendering tool; acceleration is guesswork, and one speed change means redoing everything
- “B moves only after A arrives” interlock logic is unmaintainable with keyframes
- Export a 2 GB video for the customer — with a fixed camera angle
WITH MOTION
- A standalone app: import STEP and go — works with any CAD
- Parametric motion: change one max-velocity number and the S-curve recalculates
- Signals, waits and interlocks are explicit blocks — the whole logic on one canvas
- Free Player plus QR-code sharing; the customer rotates the view freely
VISUAL LOGIC EDITOR
Choreograph a whole production line like building blocks
16 logic blocks: loops, branches, signal emit/wait, data channels, request–response handshakes. “The gripper picks only after the conveyor arrives” — drop a few blocks, wire them up, done.
- Blocks highlight live during playback — debug your mechanism like a debugger
- Flow Overview draws every signal relationship on one map
INDUSTRIAL MOTION PROFILES
The animation moves the way the machine moves
Constant, trapezoidal, S-curve (jerk-limited) and instant — four velocity profiles taken from real electromechanical equipment, not keyframe interpolation.
- Interrupt responses triggered by collision, signal or distance: pause, slow down, branch
- Smart Target: ten axis-order path strategies for pick-and-place moves
SHARE ANYWHERE
Your customer installs nothing
Export a .dma animation package for the free DynMech Player to play offline, or upload once to get a QR code — a phone scan is all it takes. glTF export brings the animation into web pages and slides.
REACTIVE SIMULATION
The simulation reacts to events
A pusher advances, an obstacle enters its path — the motion pauses and waits, then resumes when the path clears. Or slows down. Or branches. Safety curtains, limit switches and interlocks can all be rehearsed.
AI ASSISTANT
Say it, and the motion is configured ADD-ON SUBSCRIPTION
“Rotate the arm 90° around Z, then move up 50 mm.” The AI assistant writes the motion script and hot-reloads the scene — and it positions mechanisms too: mate this face to that one, leave a 5 mm gap, align the pin to the hole. Available as an add-on subscription.
The stage is empty — ask for a part to begin.
This demo can：create a box or cylinder · set a rotation or translation · choose a velocity profile · recolour · play
It cannot：import CAD, build assemblies, run collision logic or export — that is the desktop app.
Design scope
Motion is a motion choreography and presentation tool, not an FEA or dynamics solver: it does not compute forces, torque loads or structural stress, and its collision handling is bounding-box based — precise interference checking stays in your CAD. Use it to decide, verify and communicate how the machine moves.
FreeCAD users: this is the motion module you were missing
FreeCAD covers modeling; Motion covers movement. File → Export → STEP, then drop the file into Motion. Read the FreeCAD workflow guide →

Frequently asked questions
Can I animate a STEP file without SolidWorks?
Yes. DynMech Motion is a standalone desktop application for Windows and macOS. It imports STEP and IGES files directly — exported from FreeCAD, SolidWorks, Inventor, CATIA or any other CAD — and needs no CAD installation or license on the same machine.
Is DynMech Motion an alternative to SolidWorks Motion?
For demonstrating and choreographing machine movement, yes — and it works with assemblies from any CAD via STEP. It focuses on motion choreography, signal logic and shareable animations rather than force/torque analysis.
How do my customers view the animation?
Three ways, none requiring a paid license: the free DynMech Player plays .dma packages offline with a free camera; an online share link with QR code opens on a phone; and glTF (.glb) export embeds in web pages and PowerPoint.
Does the motion look realistic?
Motion uses industrial velocity profiles — trapezoidal and jerk-limited S-curves with configurable velocity, acceleration and jerk — the same shapes real servo drives execute, so cycle timing and the feel of acceleration match the physical machine.
What CAD formats can I import?
STEP (.step/.stp, recommended — assembly hierarchy and colors preserved) and IGES (.iges/.igs). Modified assemblies can also be exported back to STEP.
Is there a free version?
The 7-day trial has every feature. The DynMech Player is free forever, so viewing and distributing finished animations never costs anything. For a free DynMech tool, see CycleView — our cycle-time charting app.
What languages does the interface support?
English and Simplified Chinese ship built in. The UI is fully translatable through open JSON language packs: export the template from Preferences, translate it, drop it in the languages folder, and your language appears in the list — user packs can even override the official ones.
