QCAD: Free and open-source AutoCAD alternative

Learn how to select drawings in qcad using single-click, shift-click for multi-select, solid and dashed window selections (inside vs touching), double-click for connected entities, and keyboard delete, undo, and redo.

Master precise drafting in QCAD by configuring auto snap options, using reference points, endpoints, midpoints, and intersections, and toggling free snap for unrestricted point placement.

Discover how to organize drawings with layers in QCAD: create and edit layers, assign colors, line weight and line type, switch active layers, and move entities with the property editor.

Measure distances and angles in QCAD using the info menu, including point-to-point distances, angle checks, polar position, and coordinate retrieval.

Learn how polylines combine line segments and arcs into a single object in QCAD, and how to mix them, measure polygonal area, and explode back to lines.

Learn to construct a tangent between two circles using an arc, a universal technical drawing technique applicable in any software, with QCAD, AutoCAD, or Rhinoceros.

Explore drafting with shapes in qcad by creating a small architectural room, setting metric units, offsetting walls by 0.15 m, and using rectangles, polylines, and hatch to define walls.

Explore how to break segments in QCAD using breakout segment and breakout manual, including removing lines, setting break points, and exploding polylines for editing.

Master creating and using blocks in QCAD to group drawing elements into reusable instances with a defined insertion point. Insert, edit, and explode blocks to update references across your drawing.

Learn to configure the library browser in QCAD by adding library sources with DXF blocks, restart QCAD, and insert external blocks into your design via drag-and-drop, with layers auto-created.

explore the miscellaneous tools in QCAD, including draw options for construction lines, text along arc, and text aligned leader and leader from selected text to annotate curved objects.

In QCAD, add missing wall by drawing a line in the walls layer and offset it 0.075 for a 0.15 thickness, using auto trim or a breakout segment at intersections.

Discover how to create a page layout in the QCAD community edition for printing to PDF, including scaling a page, adding a border and a title block, and auto centering.

Explore QCAD Pro, the perpetual license version with one year of updates, and learn to open and save DXF and DDG files via Open Design Alliance converters and layer management.
