Information, tutorials, and tips for LibreCAD, an open-source CAD program.

LibreCAD vs QCAD

LibreCAD vs QCAD

On the surface QCAD and LibreCAD and every other 2D CAD software is the same, offering the same basic tools, user interface, and supported file formats. The small differences will either have you praising the software developers or cursing them as you spend your precious time fiddling with the quirks. In 2011 LibreCAD was forked from QCAD version 2. In the software development community, forking is the process of duplicating a project and having it be developed by a different group of engineers.
LibreCAD Drawing Units

LibreCAD Convert Drawing Units

Fixing the unit type of LibreCAD drawings is simple, not fixing it will cause lots of problems down the road. Depending on whether you want the drawing to remain the same physical size or to just correct setting the wrong unit type, there are two ways to go about it. Fixing Incorrect Unit Type If you started a drawing without realizing it was drawn while set to the wrong unit, changing to a different unit is easy.

LibreCAD Custom Hatch Patterns

Add style to your LibreCAD drawings by creating and using custom hatch patterns. LibreCAD comes packaged with 62 patterns – I counted – that will work for most cases. But there have been times when I needed a unique hatch pattern. Creating your own hatch patterns is literally the same as creating any other design inside of LibreCAD. By convention, patterns have the origin of 0,0 and do not exceed 100,100.
