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 £380.00 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.


The new KeyTERRA-FIRMA release 8 is now available. KTF 8 includes improved ground modelling with faster model creation and enhanced triangulation. This is also the first version to work with AutoCAD 2018. Existing users with current maintenance can download this best KTF ever from the Downloads page.

KTF 8 is also available to run on BricsCAD V16, BricsCAD V17, AutoCAD 2015 & 2016 and AutoCAD 2017

BricsCAD and KeyTERRA-FIRMA are supplied as perpetual licenses as one off purchases with maintenance options. You are not forced to pay every year to use the software.
