MakerSolid CAD

MakerSolid is a parametric CAD app built for makers, engineers, and product designers. Create models from scratch, import STEP files as editable solids, or bring in STL files as non-destructive reference meshes. Start with a sketch, turn it into a solid, refine the design, and export it for slicing, 3D printing, or use in another CAD workflow. Create prototypes, replacement parts, workshop jigs, hobby projects, and useful everyday objects. Use project variables and unit-aware formulas across supported parameter inputs to create reusable relationships, calculate dimensions, and update your design from one place. Learn directly in the app with guided, hands-on walkthroughs covering sketches, dimensions, feature history, transforms, and core solid-modeling workflows. Sketch precisely: - Lines, rectangles, circles, arcs, splines, polygons, slots, and freehand curves - Smart dimensions for size, placement, spacing, angles, and clearances, plus geometric constraints - Trim, Boundary Trim, offset, fillet, chamfer, extend, mirror, and pattern tools - SVG and DXF import for working from existing outlines - Reference images for tracing and visual guidance - Sketches on standard planes, construction planes, or planar model faces Model solid geometry: - Box and cylinder primitives - Extrude from closed sketch profiles or planar faces, with distance, Up to Face/Plane, Up to Body, Up to Next, and Through All end conditions - Revolve closed sketch profiles around an axis - Sweep and loft through profiles and paths - Hole tools and cosmetic or modeled threads, including standard and custom internal/external threads, multi-start options, clearance allowance, and chamfered ends - Parametric external and internal spur gears with customizable teeth, module, pressure angle, backlash, bore, and placement - Associative Wrap for placing sketch profiles and text onto planar, cylindrical, and conical faces - Fillet, chamfer, shell, draft, and Press Pull - Split, combine, mirror, transform, and linear or circular patterns - Construction planes and axes - Face, edge, body, and closed-profile selection directly in the 3D viewport - Feature history with repeatable edits and suppression - STEP imports that remain editable with solid-modeling tools - Select whole objects and move, rotate, or scale them directly with Object Select and the Transform Gizmo - Import STL reference meshes for positioning, comparison, tracing, and visual context - Parametric external and internal spur gears with customizable teeth, module, pressure angle, backlash, bore, and placement - Coils for springs and other helical solids, with variable pitch, tapering, custom sections, and end treatments - Helix and flat-spiral paths for use with Sweep and other modeling operations - Position bodies precisely using coordinates, reference points, center alignment, face alignment, or placement between bodies, with associative History editing Inspect and present your designs: - Measure model geometry - Use X-Ray Mode and adjustable Section Analysis views - Assign materials and colors to bodies - Preview materials with progressive raytracing - Capture preview images, including transparent PNG output Prepare for manufacturing and 3D printing: - Z-up manufacturing coordinates - STEP, STL, and 3MF export - Local project storage, duplication, sharing, and project thumbnails - Support for Apple Pencil, touch, keyboard, and pointer input Try every visible, stable sketching and solid-modeling tool in Demo. Demo users can keep up to two projects, add up to 10 modeling features per project, and complete two total STEP, STL, or 3MF exports. Unlock MakerSolid with a one-time purchase for unlimited projects, unlimited modeling history, unlimited STEP, STL, and 3MF exports, project duplication and sharing, custom project storage, and clean preview images without the Demo watermark. There are no subscriptions, your design work stays on your device, and you can continue working offline.
