BricsCAD is the fantastic alternative to AutoCAD and can be purchased directly from us here in the UK. Developed by Bricsys NV in Belgium, BricsCAD is .dwg based, has a high level of compatibility with AutoCAD and with a licence costing from as little as £335.00 is amazing value for money. BricsCAD V14 Pro is a great platform for KTF and hundreds of other "add on" applications and costs from £460.00.
