THE PARAMETRIC LOOP

Sketch it. Constrain it. Build it.
Change your mind.

01

Sketch

Draw lines, arcs, circles, and splines with your finger or Apple Pencil. Start with the geometry your part needs.

02

Constrain

Add dimensions and geometric constraints to define your design and keep related geometry working together.

03

Build

Extrude, revolve, loft, and refine your solids. Move from a precise sketch to a part you can make.

04 / EDIT

Keep every decision editable.

Revisit a sketch or feature, adjust its parameters, and rebuild your model from that point forward.

INCLUDED FREE

The tools to finish a part.
Room for your next one.

Keep creating local projects, bring in STEP files, and choose the STL quality your print needs. These tools are part of Arc3D’s free offering at launch.

Unlimited

Keep every project.

Create as many local projects as you need. Save each idea and keep refining it.

.step

Bring your CAD files.

Import STEP parts and export solid or surface geometry to keep working across CAD tools.

.stl

Choose your print quality.

Use Draft, Standard, Fine, or custom tolerances. Set units and export one file or a file per body.

Sketch precisely. Dimensions, constraints, Trim, Offset, Mirror, and projected edges. Work from calibrated reference images.

Build and refine. Extrude, Revolve, Loft, Fillet, Chamfer, Shell, threads, and booleans.

Keep it editable. Feature history, rollback, named parameters, and formulas.

OPTIONAL RADIAL MENU

Shortcuts for
power users.

Use the tool rail for everyday modeling. When you want a shortcut, press and hold on the canvas to open the radial menu. Its commands change with your selection.

The top face of an adjustable camera mount highlights blue. Sketch in the radial menu opens a sketch on that face. Two circles are drawn on either side of the center slot. Both circle profiles are selected and cut through the plate, leaving two open holes.

PARAMETERS PANEL

Set a dimension once.

Give dimensions names and reuse them across sketches and features. In the Desktop Speaker, formulas use cabinet height to calculate where the woofer and tweeter sit.
