Undet Software Suite

At Maltby Surveys we are currently using the Undet plugin suite across all of our CAD authoring platforms.

This feature packed software is easy to use and quick to load, allowing extremely large data sets to be visualized and worked upon in a very fast and efficient manner.

We have had Undet for a number of years now and it is used by all of our CAD/Revit Modellers on a daily basis providing a vital component in their modelling workflow, and, having used many point cloud tools in the past (Pointools, cloudworx, Recap etc) Undet is certainly the best we have used to date.

The support and communication that the team provide is outstanding, with any issue resolved in a quick and professional manner. The team welcomes feedback and listens to their users by adding additional features where possible.

Undet also have a browser plugin that links to Faro Websharecloud and the Navis viewing platform which, when connected, will provide a link between the online viewers and the cad software. This link allows the user to navigate and create points/lines in CAD by simply clicking in the viewer.

Well done Undet, keep up the great work

Undet solved our point cloud extraction problem brilliantly. We needed a way to extract building geometry from point clouds so that we could design and dimension Energiesprong type retrofit panels. The process had to be fast, easy to use, easy to learn, precise and reliable. Undet does it all.

The plane and corner extraction tools give us the basic building outline quickly with the accuracy we need (+/- 6mm)- even with a non-survey grade scanner.

Two other features combine to make locating the building details fast, reliable and accurate. The first is the ability to increase the visible point cloud density as you shrink the clipping box. The second is the ability to colour the points according to the distance from the clipping plain. Genius!

Review of Undet for AutoCAD by Jersey Laser Scanning

I run a 3D laser survey company which produces as built 3D models and Topographical surveys in Revit. I have just changed my entire workflow from AutoCAD to Revit so still have some level of familiarity with AutoCAD.

I was looking for ground cleaning software that could handle some of the large topographical files I collect. With a number of the products that I fond during my research it was hard to find a blend that wasn’t complicated, prone to blue screening due to memory limitations or with limits of the size of point clouds. Undet for AutoCAD seemed to have what I wanted, didn’t seem to require me to recalibrate my brain to learn something brand new, didn’t appear brutally expensive and had some pretty good guides on their YouTube channel. I used to manually remove unwanted vegetation from point clouds but for properties with overgrown gardens it was becoming disproportionately time consuming, was difficult and wasn’t cost effective for my time spent so decided to make the leap to paying for something that would help. Undet don’t do the ground cleaning software for Revit at the time of writing this review but allegedly it will soon be available. Once I have the mesh from Undet (which I use in AutoCAD Civil 3D) I then import into Revit and create a Revit Topo.

Undet for AutoCAD review from my perspective
– I needed something that removed everything except the bare ground surface incl trees, cars, plants, long grass, properties etc. I must confess Undet for AutoCAD does that very well. It does benefit from some help by me cutting out the really obvious vertical surfaces of properties before I ask it to clean and then create a mesh surface. This is due to some natural creep up in elevation as the algorithm clearly tries to average out the height changes. Marius from the Undet team got back to me immediately with some tweaks to help improve this very quickly and they work well. I really appreciated someone telling me the answer without having to trawl forums.
– The Undet Team were very good by giving me a week of trial run. I ran out of time due to a client with a time constraint and didn’t complete all the testing I needed and asked for another week which they gave me straight away. On top of the product actually working it was probably this level of them being prepared to be flexible and helpful that clinched the deal for me.
– They had a month by month option for Undet for AutoCAD costing $120 which was at the upper limit of what I was prepared to pay ( I would have rated it 5 stars and raved about it if it was $100) but it is very convenient to decide if I need it each month as doing good detailed topos with contours from sites with heavy vegetation appears to be a unique selling point at the moment. When it becomes less fashionable I can save my cash for when a job comes up.
– The software carried through all the DGPS geolocation I applied that I was worried about losing during the process, so big tick from me.
– There is a deformation analysis tool which you can tune by colour and level to give a heatmap of elevations. Very cool, quick and useful for structural engineers or ground work guys who want to check on the integrity of a surface (horizontal, vertical or otherwise)
– Keen to test how to join meshes together to make 3D meshes but if it works as well as the rest of the product then it should be fine.

Thumbs up from me, looking forward to see if they manage to translate the same product into Revit.

Undet drives productivity for Siteline Geomatics

We have used Undet for a year now and have found the improvements in our workflow to be significant. The interface is very user-friendly and highly intuitive and the software incredibly stable, allowing us to work with far larger data sets within the AutoCAD environment than was previously possible.

We are now able to import an entire scan project into CAD, no longer wasting time pre-processing it into smaller chunks nor loading and unloading them whilst drawing – everything is readily available at our fingertips. Visually, the quality of the data is crisp and the colour control options vast. The colour ramps are fully customisable to suit the user and colour can applied on a project, sub-group, or individual scan basis. This not only improves visibility of the data, but has proven hugely beneficial in the interrogation of it, allowing us to assess the accuracy of crossover data between scans quickly and easily within CAD. Similarly, the flexibility offered by the clipping tools and the fact the regions are auto saved for re-use until deleted, mean the user has maximum control over the data.

Recently we scanned a substantial hotel, converted from adjoining large Victorian properties, resulting in what can only be described as a “rabbit warren” of a building. This included a number of stairwells, some of the ones away from the public areas being very tight and winding. We were able to very easily isolate these areas, switching on only a selection of scans, viewing them in 3D and utilising colour controls to make sense of them. Any confusion or visualisation problems previously caused by crossover data have been all but eliminated. Conversely, by reducing the visual density of the point cloud, we could work on extensive floor plans or cross sections with a huge spread of data visible all at once, enabling us to generate the significant line-work very quickly.

Using Undet has helped us to improve our models and to reduce the time spent in creating them considerably, allowing us to reduce costs and improve on delivery times. The time spent in producing models is now typically 30% less than it was previously.

With Undet we can easily create classes and scan groups e.g. scans inside and outside the railway. This allows us to turn off areas of point cloud data that are not required and concentrate only on the area of interest. The resulting display is both quicker and more detailed.

The ease of handling within Undet when creating point cloud view sections has helped us to create models in a much more timely and efficient manner but the tool that has most impressed is the SmartBoard. With SmartBoard you can easily create profiles or cross sections with the required depth; an offset step can be managed. This can be useful for creating profile sections or measuring bridge heights.

Meshing and creating surfaces are also really quick and easy with this software. The parameters can be altered to create the surface to meet your needs. The True Scan View Navigation inside AutoCAD is another advantage of this software. You can easily check how accurate your model is compared to the scan view.

To sum up, the main value of this software is its efficiency and ease of use when working with point clouds in AutoCAD. You can save time and reduce costs on projects. A great and useful tool.

quotes iconRoger Thurston

UNDET has a fantastic usability factor and has the ability to manage a high point count without performance issues. In short, UNDET is simple, practical and applicable.

We use UNDET on a daily basis. One particular example of how we use the software is when we scanned a local school with a Leica P20 scanner, totalling nearly 100 individual scans. Following the registration process, we utilising UNDET to help us to separate scans of each floor plan together with the building’s exterior in order to process the external elevations.
UNDET makes sense when viewed from a technical perspective, but the software also makes commercial sense to us as it has given us huge advantages in terms of time-saving benefits as we can now process large point counts with significant time reductions. The software is less disruptive to our work flow and has fewer software conflicts, meaning we can work faster and much more efficiently.

The Undet for SketchUp extension has given a massive boost to our company

The Undet for SketchUp extension has given a massive boost to our company in terms of productivity, product quality, and efficiency. We build bespoke frameless structural glass extensions to fit snugly against buildings, which are seldom flat or even, using multiple glass panels weighing up to 800kg each, which either fit or they don’t. We used to measure everything carefully by hand the old-fashioned way, but how ever hard we tried we often had to remake wrongly sized panels which cost a fortune.

Since using Undet for Sketchup in February 2018 everything is so much easier, and so far, we haven’t remade a single panel. We now capture a buildings geometry as a point cloud using a Faro 3D laser scanner which we can import easily into SketchUp using the Undet for SketchUp extension irrespective of its size.

We then create a highly accurate surface mesh using Undets Feature Extraction Tools and take sections where the glass sits enabling us to draw our glass profiles with incredible accuracy. The difference using the Undet for Sketchup extension is simply staggering in terms of speed, accuracy, and cost, and we cannot thank Undet enough.

A bonus is that the software keeps improving, and any early bugs have now been eliminated.

Undet for Sketchup - Works Like a Charm

I’m grateful to the Undet team for developing such a useful piece of software and recognizing Sketchup as a significant design tool worthy of a plugin.
I use Undet every day to create Sketchup models from my laser scanners e57 files. The newly released “Scenes” functionality is super slick and enables me to record cloud point limit boxes and other cloud settings on top of SU’s scene settings, which allows me to juxtapose my cloud and model just right for unique visuals and return to the state when needed.
The CAD team is also fantastic at converting point cloud data to Sketchup 3D models with layers and detail levels specified by the client. Marius is responsive and wonderful at asking questions and requesting examples of your CAD & modeling work to ensure the final model meets your expectations.
Keep up the great work!
