Tools

Draw
Line, polyline, circle, arc, ellipse, rectangle, polygon, point, multi-line text, leader, hatch, solid fill, blocks.
Modify
Move, copy, rotate, scale, mirror, stretch, trim, extend, offset, fillet, chamfer, array, explode, join, grips, 3D rotate, 3D mirror, copy and paste.
Measure
Linear, aligned, radius, diameter, angular and ordinate dimensions. Editable dimension text. ISO lettering.
Precision
Typed coordinates, ortho, alignment tracking, dynamic input, direct distance entry, command completion and fourteen object-snap modes switchable one at a time.
Organise
A modern layering system: the layers rise as a stack of tracing plates beside the cursor, each showing what is on it — point at one to see its layer alone, click to draw on it, right-click for its properties. Named layers, visibility, locking, colours, line types, ISO lineweights, a text height per layer, per-object colour, line type and lettering, sheets and layouts, paper space.
Electrical
A second bench for schematics: IEC 60617 symbols with pins, wires that follow the parts they join, junction dots and hops where wires cross, wire numbers, parts list and wire list as CSV.
HelCAD's electrical bench: a relay start circuit with a 24 V source, fuse, start button, relay coil, latching and main contacts, a motor and a run lamp, every part designated and rated, the wires joined with dots
Electrical designing couldn't be any easier with HelCAD

3D

  • A working plane: three points, an object's plane, or moved along its normal
  • Lines, profiles, circles and arcs drawn on it
  • Extrude, revolve, sweep, loft, push-pull
  • Box, cylinder, sphere, torus, wedge, cone, pyramid, wall, slice
  • Solid text: a word as one solid per letter, counters as holes, ready to print
  • Boolean operations: subtraction, union and intersection
  • Edge fillets on solids
  • Exact fillets, chamfers and shells (Open CASCADE)
  • STEP import and export
  • Solids lit and shaded, hidden lines removed, shadow on the ground
  • Orbiting view, above and below the ground
  • Binary STL with manifold validation
  • 3MF with millimetre units
  • Wavefront OBJ mesh export
