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. Download for a free 30 day evaluation and contact us for a quotation or if you have any technical questions. See the press release below.

An important new KTF release is now available. A new on-line help system has been introduced, a revised menu and some new functions contribute in making this our most comprehensive and easy to use version so far. KTF 7.5447 is for BricsCAD V14 (just one of six supported platforms).

AutoTURN Pro 3D for BricsCAD V14 has been released by Transoft Solutions for advanced swept path analysis.

The new Ordnance Survey digital height product OS Terrain® 5 is recommended for not just ZTV but for a broader range of ground modelling projects.
