    • BricsCAD is the excellent 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 £390.00 is outstanding value. BricsCAD V17 Pro is a great platform for KTF and hundreds of other "add on" applications and costs from only £500.00. Download for a free 30 day evaluation and contact us for a quotation or if you have any technical questions.

      Most BricsCAD and KeyTERRA-FIRMA licenses are supplied as perpetual licenses i.e. a one-off purchase with maintenance options. You are not forced to pay every year to continue to use the software but invited to renew the maintenance. With current maintenance you will benefit from the latest versions.
