No problem, just a little experience measuring earthworks from working it out with manually drawn cross sections and HP45 calculator (quite a few years ago) to using LSS. It helps to understand what is going on before blindly accepting a computer printout. Glad to be of help.

PujanG There are many methods of calculating earthworks volumes but they all take the same principle. Area = length x width Volume = area x height Given that we use 3D coordinates expressed as X, Y and Z, they are always dimensioned at right angles to each other from an origin. Therefore as...

Mmmmm... XP, AutoCAD, video drivers... There is an issue with NVidia graphics drivers when running XP on (some) computers built for later Windows systems. All sorts of problems manifest themselves with this and much time and effort has been used to try and sort it. This was even found on a...

You can download and install a very useful utility from www.scriptsheets.com. A simple fix for people who don't have "file insert" and can be set-up to provide very detailed drawings from calculated results in Excel. Enjoy...

Kickers are generally a starter shape of a wall or column approximately 150mm (6") tall cast on a slab or foundation to position shutters and restrain against movement. Shutters are formwork to define the shape of the concrete pour. We are curious to find out how the construction accuracy...

Keep us informed how you get on and what accuracies you are achieving in the final positions of elements.

There must be a way of captivating the shutters during pours. If the shutters have a notch, then the installers will require these positions marked out. If ther are no kickers then is the column fixed by starter bars or dowel bars? or is there a recess in the floor to receive each column? The...

What specification are you working to? The general method is to accurately set out and construct a "kicker" for each column (a starter shape of the concrete element about 100 to 150mm high). The shutters can be set to this kicker and kept vertical by plumb-bob. The concrete gang will make up...

You probably need to install the correct driver for the Leica cable before use. These are usually avaiable from a Leica reseller. The TPS 1200 uses the GEV189 cable and cannot be recognised if the driver is not installed. I would suggest contacting a Leica dealer who's support line should...

Why can't you use the custom format "hh:mm:ss.000" to achieve your goal. Ian

Sounds like a comms error. Perhaps a call to a Topcon rep will reveal a more specific reason and suggest a solution.

Just a quick addition Our corporate IT policy dictates that we are restricted to Windows XP Pro SP3. This has exposed a bug in NVIDIA graphics drivers which dramatically slows down the production of graphics - so beware.... So much for splashing out on a top flight "CAD spec" mobile workstation.

Also this method can determine your DEFAULT settings for units, text styles, dimension styles as well as layers etc. regards, Ian

You need to set up your template file (.dwt) used for start-up. Identify your template file by choosing Tools>Options>Files>Template Settings>Default Template File Name for QNEW and open that dwg. In model space: Type UCS World (to set the UCS to World UCS) Type Plan Current (to set the...

Attributes to blocks are completely user definable so your examples are referenced to the items of information the author of the block set up. Whether the attribute should be visible is again down to how it was set up in the first place. This (to my knowledge) can only be assessed when a block...

ACAD attributes can also be invisible. These are still part of the block information but are not plotted. You can extract the attributes into a table, spreadsheet or database for BOQ etc. regards Cherrypicker

Often wondered if this is something to do with the clipboard overload combined with undo capability. I normally close Excel down, restart and it seems to work OK then. Anyone else have a solution?

Modify > Object > Attribute > Block Attribute Manager.... or at the Command prompt, enter BATTMAN hope this helps....

Just another stab--- Have you taken enough readings on each face to compensate any errors in accuracy of the vertical circle of your instrument? If you are usually low it would initially suggest an error in your instrument if the readings are only taken on one face. good luck...

"What flavor of CAD?"... I forgot to mention the cylinder is assumed to be vertical (or data exported from AutoCAD when the UCS is aligned to indicate it as such). This is broadly the technique I use to illustrate surveyed deviations from a true cylinder using the most suitable features from...
