Sketch Studio
parametric 2D sketching with simple 3D
Parametric 2D sketching with design variables, extrude and revolve to simple 3D parts, and STEP or STL export, in the browser.
Product pages are in English.
Highlights
- Named design variables and expressions drive points and dimensions across the whole layout
- Lines, arcs, circles, rectangles and fillets in an assembly of components on their own planes
- Edit the solid in 3D: pull a face, offset a wall, move a hole, round or chamfer an edge
- Import a STEP file, sketch on a planar face and convert its projected edges into geometry
- Export STL or STEP with true arcs, or publish a part to other Twinsys tools
A question it answers
Can I lay out this bracket profile driven by a single length variable, pick it up off the real machined face of an existing STEP part, and get an STL of the extruded shape?What you put in
Design variables and expressions, sketch entities (line, arc, circle, rectangle, corner fillet, construction and infinite reference lines), a sketch plane and placement marker per component, extrude depth or revolve, and optionally a STEP file with a selected planar face.
What you get
A parametric 2D sketch with dimensions and snapping, a product tree (assembly → components → curves → surfaces/solid), a 3D preview, STL export, save/load of the project as JSON, and 3D face and edge picking with direct edits — pull a cap depth, offset a straight wall, round an edge — that write back into the parameters rather than into the mesh.
