Parametric, all the way down

Every feature keeps its inputs. Change a sketch dimension or a named parameter and the model rebuilds from its history.

Sketches that behave

Geometric constraints and dimensions are one model, solved live. Type 1/4", 6mm or wall + 2 anywhere a length goes.

From model to machine

Flat outlines and nesting for the laser or router today; a CAM workspace for mills and lathes is in development.

Cahaba Studio: Start from a scan — **Start from a scan**Bring in the mesh from your 3D scanner, noise and all. Here, a worn pillow block bearing housing.

Cahaba Studio: Find the faces in it — **Find the faces in it**Auto Regions sorts the scan into the planes and cylinders the part was made from.

Cahaba Studio: Trace a section — **Trace a section**Cut through the scan and get a sketch of clean lines and circles, ready to dimension and extrude.

Cahaba Studio: Check it against the scan — **Check it against the scan**The rebuilt solid colored by how far the scan sits from it: green is within tolerance, warm is proud.

Cahaba Studio: Sketches with dimensions — **Sketches with dimensions**Constraints and dimensions hold the shape. Change a number and the geometry follows.

Cahaba Studio: See it before you commit — **See it before you commit**Previews show material being added in green and removed in red, with the values right beside the model.

Cahaba Studio: A history you can edit — **A history you can edit**Every step stays editable: reopen a sketch or a feature and the rest of the part rebuilds.

Cahaba Studio: From model to toolpath — **From model to toolpath**The solid rebuilt from the scan, set up with the spindle along its bore: facing, a contour, the bore and a chamfer, with the stock that is left. CAM is experimental in this release.

Works with Claude

Model by conversation.

Cahaba Studio has a built-in MCP server, so an AI assistant can sketch, constrain, extrude and measure in your open document while you watch. Every change it makes lands in your undo history.
