Orbit, inspect, and verify every joint before a single piece of tube is cut.
3D Assembly View

See exactly how every tube fits.

Orbit and inspect your assembly from any angle before making the first cut. Solid or skeleton render mode.

Bends and Branches

Build complex assemblies that are difficult to model by hand.

Draw multi-bend runs and attach branches anywhere along a tube — including directly on bend arcs.

Instant Build Packet

Walk into the shop with every cut already planned. PRO

Every tube listed with length and end treatment. Includes printable cope & miter templates, 3D model export, and G-code for plasma or CNC cutting.

No Guessing. No Rework.
FitUp handles the geometry so you can focus on the build.

3D Layout

Place tubes in a live 3D scene and see the whole assembly take shape before cutting a single piece.

Draw Mode

Sketch your layout point by point. Snaps to grid and existing endpoints for clean, accurate joins every time.

Bend Runs

Add radius bends to any tube run and see the arc geometry update instantly. No manual calculations.

Branches on Bends

Attach branch connections anywhere — including directly on bend arcs. Drag to reposition freely.

Automatically calculate every tube length.

Every piece listed with length, angles, and end treatment — calculated automatically from your layout.

Print full-size templates that wrap directly around the tube.

Export a printable 1:1 cope template for any branch joint. Wrap, mark, and cut.

3D Model Export

Export the full assembly as STL or OBJ — ready for 3D printing, CNC, or sharing with your fabricator.

G-Code Export

Generate plasma or CNC cutting paths for every cope and miter. Seam-aligned and zero-referenced for your machine.

Live Dimensions

Toggle overlays to see offsets, lengths, and arc positions on any selected piece at a glance.

Save & Reload

Save your assembly to your account or export a local file. Pick up exactly where you left off on any device.

How It Works

1

Lay Out Your Assembly

Click to draw tube runs or place individual pieces. Add bends at any point and watch the 3D model build in real time.

2

Add Branches

Click any tube to attach a branch. Drag it to the exact position — on straight sections or directly on bend arcs.

3

Joints Calculate Automatically

Miter cuts at endpoints, cope angles where branches meet pipe — all recalculated instantly whenever you adjust a piece.

4

Print Your Shop Packet

Export a ready-to-print PDF with every tube length, end treatment, cope template, and miter template — everything you need to cut and fit up.

Know every cut before you touch the saw.

Free to use. Pro unlocks assembly reports and cut templates.
