3D Engineering, Data Modelling & Visualisation




3D Engineering

Civil Modelling for Road & Rail Infrastructure, Land Development, Coastal, Mining, Metros and Tunnelling.

3D Data Modelling

Large scale data models, Point Clouds and LiDAR, GIS or localised survey.

We specialise in data communication. What would you like yours to say?

Geotechnical Data

Need to create or model geotechnical data? Develop geological surfaces? Or embed your data into CAD or BIM workflows?

3D Visualisation

Design analysis, construction process, stakeholder buy-in, high impact communication and presentation:

We build in 3D because that’s the way the real world is – we like keeping it real.

BIM & Wide Area 3D Modelling

Our data skills mean we can efficiently develop complex 3D models over wide areas with thousands of objects – whole city models.

This image shows 13,000+ 3D buildings from CAD & GIS mapping data, and a TIN ground surface built with 50,000+ raw 2D & 3D objects.

Big scale modelling for full BIM integration.

Enzdata is a boutique 3D CAD & BIM Consultancy with strengths in data processing, particularly civil infrastructure and geotechnical data workflows.

Broad project experience, wide data vocabulary and deep CAD, GIS and BIM capability. Practical civil engineering design and modelling, high impact 3D virtualisation, specialised data management solutions and impeccable presentation standards.

We aim to produce great work, and be great to work with.

How can we help?


3D is what we do.
Accurate virtual construction. 2D to 3D conversions from CAD, electronic data, or even from a sketch – the way it used to be.
If you want to see it, we can do it.


Dynamic 3D Civil design & modelling for infrastructure, mining, land development, construction.


Information Modelling for design communication, project collaboration, costs & quantities, management.


Databases, data management, AGS4, geotechnical CAD and BIM.


Engineering data analysis, systems and workflows; CAD/data interaction, extraction. Data virtualisation (‘analog to digital’).


Spatial data analysis, large datasets, GIS to CAD data conversion.

We’ve been pushing data in, out, and through CAD environments for decades.

Our highly-tuned 3D CAD, GIS and BIM modelling skills will help you design, analyse, visualise and manage your project.

We’re always up for a conversation!

Kent Langdon is the director of Enzdata Limited.

Kent has been in Civil & Geotechnical Engineering since 1993. He had spent roughly half his career in New Zealand geotechnical CAD and Civil Engineering, and the other half in UK based geotechnical data management and 3D modelling, before establishing Enzdata in 2009.

Kent enjoys Enzdata’s workflows because they tend to be both highly creative and technically challenging. He seeks quality in both modelling-accuracy and visual presentation, and is always looking for better ways to do things. Not only that, but he takes great satisfaction when given opportunity to pass on that knowledge, process, and passion to others.

For more detail on Kent’s work history, please ask for a CV via the contact form, or refer to his Linked In profile.

Kent is married to Sara and they’re kept very busy with three young children. Kent’s other passions include music, church and good red wine.

Geotechnical Data


We are geotechnical data experts. Since 2001 we have been working with geotechnical databases, geotechnical data, and data presentations – so whether you need to create, analyse, present or distribute geotechnical data – we can help.

Geotechnical BIM

Integration of geotechnical data within Civil 3D & BIM workflows.

Geotechnical Databases

We use Keynetix HoleBASE SI Professional information system to store, interrogate and analyse our geotechnical data. Talk to us about optimising your geotechnical data workflows.


We have 14 years experience with the AGS data transfer standard. AGS4 enables the electronic transfer and storage of geotechnical data regardless of software system. We have the expertise to help you provide AGS to your colleague, client, governing agency, or contractor.

Civil & BIM

Geotechnical data – boreholes, down-hole test data, sample and lab data – directly inside the CAD or BIM environment.

Kent has a unique skill set as he understands geotechnical data management and is highly proficient in AutoCAD
Civil 3D and HoleBASE SI. It is always a pleasure to recommend Kent to our customers via our Technical Specialist
Network as I know Kent will exceed the customer’s requirements for 3D visualisation or Civil 3D training. Kent is
simply one of the best AutoCAD Civil 3D users I have worked with.

Roger Chandler

Managing Director, Keynetix Limited

Keynetix Technical Specialist

We have been identified by Keynetix as an expert in the field of engineering & geotechnical data. Enzdata have been using Keynetix products HoleBASE 3.1 and KeyHOLE for AutoCAD since 2001, and more recently we’ve upgraded to the industry leading HoleBASE SI Professional along with its Excel and Civil 3D Add-Ins. We also do great things with the humble hero of their software range – KeyAGS for Excel.

We offer consulting services and training to those who seek to improve their geotechnical data workflows, work with AGS data, and how best to utilise their industry leading HoleBASE SI products.
