AutoCAD geology models can now be dynamically updated from edited fence diagrams.

A new version of the Keynetix HoleBASE SI Extension for Civil 3D will revolutionise the way engineers enhance geology ground models from edited section and fence diagrams. The new features have taken two years to develop, as part of the Keynetix and British Geological Survey (BGS) “BIM for the subsurface” project, funded by Innovate UK.

Interviews with Keynetix customers and BGS staff highlighted that many engineers and geologists found it easier to draw in 2D to help them develop 3D models.

Dynamic 3D geology models

Keynetix software already created dynamic sections, based on changes to the 3D model, but the interviews showed users also needed sections to drive the model creation.

This is exactly what Keynetix has done. With the new release, users can use the generated sections and fence diagrams, update them and see the edited information dynamically incorporated back into the 3D model.

“Judging from feedback from clients, I believe this is another game changer,” said Gary Morin, Technical Director at Keynetix. “It will allow them to better visualise and understand subsurface data which, due to time constraints, previously could only be afforded on the most prestigious projects.

“The introduction of these features is very timely, as more organisations are using 3D fence diagrams to share complex subsurface geological information with the wider team, BM environments and clients. I look forward to helping users make the most of these new features over the coming months.”

Fence Diagrams

Fence diagrams, sometimes referred to as 3D sections, were added to the HoleBASE SI Extension for Civil 3D in 2017. Now, any edits to sections will automatically update the 3D fence diagram and the AutoCAD Civil surfaces.

“The work that Keynetix has done on this new release has allowed the geological modelling aspect of a project to be placed back in the hands of geologists. The easy-to-use interface means a model can be constructed without much AutoCAD knowledge. This is a great step forward for the product and industry,” said BGS Team Leader of Geological Modelling Systems and Innovate UK team member Holger Kessler.

“Working with Keynetix has been a great experience; they are easy to work with, proactive and professional. We are pleased to see the BIM for the subsurface project deliverables becoming available,” added Rachel Dearden, BGS Hydrogeologist, who is leading the BGS team for the Innovate UK project.

Free workshops and one-to-one consultations

Gary Morin will be holding free training sessions and one-to-one consultations on the new features and other Civil 3D and BIM-related questions at Geotechnica 2018 at the Warwick Exhibition Ground.
