CL900 tablet for survey

November 3, 2011

Tablet PCs come and tablet PCs go but the problem of the field PC remains the same. What we need is a reliable, daylight readable and portable device that will run CAD all day long so that we can see what we are doing as we do it. Not much to ask, and as the tablet wars hot up things should be getting better for the practitioner.My workhorse is the Motion Le1600 which will run most of what I need, will power up all day long on 3 batteries and has a just about daylight readable screen.

We have been friends for years. We get on. There is nothing wrong with it, its a great teaching tool, but it’s too long in the tooth to hold up AutoCAD 2012 or Windows 7 so well…and it’s starting to feel heavy compared to some of the newer kit that’s begining to appear. Its logical replacement is the Motion J3500 but, being of reduced means, I have decided to look at what can be done at the budget ‘netbook’ end of the market and this is where I met the remarkable CL900.

Suddenly, after using these things for years, there is a rash of apparently cheap Android/ Ios/HP OS tablets available on any high street (well retail park anyway) for well less than a grand. Having tried to do something useful with the beguiling iPad I feel I have learnt the ‘if it isn’t Windows…. it isn’t Windows’ (or to put it another way if you can’t run proper CAD on it it’s an expensive door stop) lesson the hard way. A quick look at what you can run on an Android unit and the lovely cheapness doesn’t look so good.So if I have to lug a tablet around the world (and believe me, I do) what do I expect it to do?

The essentials are CAD, Bluetooth, Serial Comms (USB or Dsub9) email and internet, I also need to be able to write reports, read and write PDF, handle images to a degree (more on this later) and present PowerPoints. It may well be madness to expect the Intel Atom (even at 1.5Ghz with 2GB of ram?) platform to manage all this so let’s start with getting to grips with CAD on a netbook- can it work?

With only 1.5Ghz prosessing speed and a max of 2GB ram you would think any current release of CAD (they only get bigger and slower don’t they!) would be a non-starter on the CL900- but if all you neeed to do is build wireframes and line drawings current release BricsCAD v10/11 holds up well ( yes it’s a bit slow to start…nothing new there!) and so I’m all set to find out if it will do a good days work.

As you would expect with a light weight processor and solid state HD package power uptake is good and the battery warnings don’t begin to bleat until at least 8 hours runtime!

3 stations and 1137 points plotted into CAD and 49% battery left on its first field day is a very good result…I’m begining to like this!

The battery life for field survey is very good indeed. We did a full days worth and didn’t need to deploy the external battery pack: with a Powerbank MP3450 a comfortable 10 hours runtime should be easily achievable.

The outdoors screen view is ok, its not the best but its workable. CAD runs ok if you accept its going to be a bit laggy with regens, opening up and the obvious graphics grief with image files.

Now the other stuff I want it to do….

I can’t expect this little chip to push photos around in Photoshop so I have installed ‘Advanced JPEG Compressor’ to get the basics of crop and web-ready done. It’s very efective and reasonably priced too.

Writing reports is just about doable in Word (the old hardware of keyboard & mouse wins really and the single USB port is a bit of a handicap here).

Camtech supplied the CL900 and are most helpful with technical support so far (which has involved testing removal of the Ntrig interface for me: a potentially risky manoeuvre in the 1st instance).

So if you want a field tabet that will run TheoLt all day long the Motion CL900 is a good bet, its not lightning fast but it does the job. It’s light, well made and is a good example of a ‘Windows ipad’ (aWipad?) -Steve Job’s legacy may yet be a wide acceptance of the tablet form-something I believe needs to be a bit more than a locked down content browser, the CL900 isn’t quite an ipad for windows but its very close.

Over the past 9 months we have been updating you with this blog hosted on this wordpress site. It was clear this was a major success so this has now been moved to the main TheoLt.com site under News & Articles.

We look forward to seeing you there..


Unwraping Cylindrical Shapes

June 22, 2011

Following on from our previous post announcing PhoToPlan Release 7, here is a video showing the new unwrapping function introduced in the “Ultimate” version. Please contact us for more information.


Ortho Image from PointCloud’s

June 18, 2011

Following on from our previous post announcing PointCloud Release 7, here is a video showing one of the new (and probably most useful) functions.

Then ortho image is easily created from a laser scanned point cloud in AutoCAD. The image is to scale and can be imported to any program that handles raster images. Draw easy elevations, great for printing or annotating for a deliverable. Contact us for more information.


PhoToPlan 7 is now available

June 15, 2011

We are pleased to announce that the latest version of kubit’s PhoToPlan software for AutoCAD is now available for download.

The new features include:

  • Support of AutoCAD 2012 and Autodesk products based on AutoCAD 2012.
  • New higher level product “PhoToPlan Ultimate”.
  • Generation of Ortho Photos from orientated images. Included in the “Ultimate” variant only.
  • Fit cylinder with just a few clicks in two orientated images. no need for marked points on the cylinder . Included in the “Pro” and “Ultimate” variants.
  • “Flatten drawing“ – project geometry to a UCS. For delivering 2D drawings from 3D wireframe.
  • “Unwrap Cylinder” – from at least one orientated image and points on the cylinder PhoToPlan will create a flat image of the surface of the cylinder. Included in the “Ultimate” variant only.

  • Create UCS from the “Dual image Draw” commands. Once defined, facades may be digitised using only a single image and with fast commands for switching between parallel planes using images only, digitising of elevations has been significantly  speeded up.
  • Improvements to the image orientation workflow. Controlling the viewports and view is vital for fast modelling. Release 7 eases this with a number of new commands.
  • Support for “Ribbons” in AutoCAD 2010 to 2012: an alternative for the classic menu and toolbars (actually takes less space than showing all toolbars)


PhoToPlan Release 7 supports All 32 bit and 64 bit versions of Windows 7, Vista and XP (Windows 2000 is no longer supported).

Each of these new features will be examined in forthcoming posts.

Release 7 is provided free of charge to existing users on subscription but please remember to request your upgraded license before installation.

A free of charge trial may be downloaded here.


Deviation Analysis and Error Mapping for kubit PointCloud

June 14, 2011

This video makes use of kubit PointCloud’s tools for analyzing variations from a defined surface. Also useful for error mapping, kubit PointCloud’s multi-section tool aids in detecting the deviation from a defined plane.


Multiple Slices and Polygon Fitting in PointCloud Pro

June 6, 2011

Kubit USA have been producing YouTube Videos showing many of the powerful features of PointCloud Pro for AutoCAD.

In this movie we automatically extract profile lines from a laser scanned tunnel using kubit PointCloud Pro for AutoCAD. Multiple slices are taken along a defined path and lines are fitted to the profile slices with the kubit “Polygon Fit” tool. These profiles can also be used easily to create a model using traditional AutoCAD modelling commands:
