What is KeyHOLE?
KeyHOLE is the ideal application to produce drawings and visual imagery quickly and cost effectively. Working seamlessly inside AutoCAD, KeyHOLE provides the powerful open modelling tools the engineer needs, and that essential connectivity between CAD and your data.
This means you can have the benefits of the world's most powerful drawing package without the prolonged learning curve usually required to release its potential. The initial investment will quickly repay itself by shorter lead times and more effective use of human resources: engineers and technicians. And there'll be more time for branding and smartening up drawings for final presentation. You'll soon be producing the highest quality output, while keeping production costs low. Your competitors will hate it, but your clients will love you. The role of CAD in Site Investigation
What KeyHOLE can do for you?
KeyHOLE connects directly to your HoleBASE data and enables an astonishing range of drawing options, from multiple cross sections to 3D visualisations. Here are some of the main features of this extraordinary package: -
Plotting Hole Locations
This can of course be done in AutoCAD without KeyHOLE: simply create a block to represent the symbol and then insert it many times by entering the co-ordinates. However, it can be a lengthy process and prone to typing errors resulting in wrong locations.
Because KeyHOLE is linked directly to your hole data, this process is fully automated, plotting all the hole locations in a just a couple of seconds. But that's not all: KeyHOLE adds elevation and other intelligent data to the block's attributes, giving it greater value and more usefulness than a simple AutoCAD entity. The symbols used to represent locations are sensitive to the hole type. As well as the standard symbol sets provided with KeyHOLE, you can easily create your own.
Section Diagrams
Although most civils-trained CAD technicians are very experienced at section drawing, it is a necessarily time-consuming business because of the need to transpose horizontal distances and projections into a vertical plane. By fully automating this process KeyHOLE reduces the time taken to a matter of seconds and eliminates the risk of human error.
Moreover, KeyHOLE can exploit ground-modelling data to create interpolated sections of the ground - something the most skilled technician would be hard-pressed to achieve at all.
Plotting Depth Related Data
One of the most common requirements for site investigations, this process can take even an experienced technician many hours to complete. Whether you require the information on the site plan, or on section diagrams, KeyHOLE handles it quickly and effortlessly.
Plotting XYZ Point Data
In order to give the engineer a quick and flexible method of identifying critical areas of the site, KeyHOLE enables the plotting of any data related to hole records as point locations. This can be virtually any numeric data held in HoleBASE, for example: moisture contents, depths of water strikes, thickness of peat, or as shown here, chemical concentrations.
Contamination Plots
The interpretation of soil and groundwater chemical test results can be a very tricky process and accurate analysis requires specialist skills. The mere presence of a determinand may or may not be significant, depending on factors such as distribution, concentrations, and present or intended land use. The main difficulty for the environmental scientist is assimilation of large data sets from many locations, and isolating hot spots and significant trends.
KeyHOLE has a number of tools to make it easier to visualise the factual data but does not attempt to analyse or interpret the recorded results. The overriding principal is that human analyst at all times remains in control of how data is interpreted and presented.
In addition to this, data can be processed by HoleBASE to produce an interpolated model of the contaminated layer, according to given determinands and trigger levels. This is then displayed in KeyHOLE to produce volumetric reports and graphics.
Digital Modelling
The term Digital Modelling refers to the process of forming a virtual 3-dimensional surface from data arranged in columns of X Location, Y Location, and Z Value. There are a number of digital modelling applications using a variety of algorithms to create models. Many of these are predictive and can actually change the data in subtle and indiscernible ways. KeyHOLE 6 employs the KeyTERRA-FIRMA modelling engine and so uses the TIN method (Triangular Irregular Network) most favoured by engineers. TIN has no predictive algorithms and only uses the data presented to it. This is vitally important when dealing with site investigation data.
There is a wide range of data sources that can be modelled, including Raw data from tables or text files, pre-processed data from HoleBASE, or directly from AutoCAD entities: blocks, points, lines, and polylines.
Of course, it is sometimes necessary for the engineer to interact with the modelling process in order to incorporate specialist knowledge such as geological faults and terrain features not picked out by the data. KeyHOLE therefore allows the user to specify break-lines or pseudo points to force changes in the model.
What can a Digital Model do for you?
Given that virtually anything can be modelled, a number of useful outputs are available, from calculated volumes of certain soils, to 3D visualations. Here are some of the options:
Contours (water, thicknesses, concentration, soil properties etc)
Isopache Colour plots
Slope & Flow Analysis
Interpolated Sections
Embankment Interfaces
Contour Plot from Model
3-Dimensional View
KeyHOLE - The perfect site investigation companion for AutoCAD
In addition to the specific functions listed here, a wide and comprehensive range of manipulation tools and utilities are provided to make otherwise quite difficult tasks easy. Here are just a few of them:
Reverse direction of polyline
Convert 3D polylines to 2D
Create AGS data from entities
Change symbols used to display boreholes
Edit legend codes and assign hatch patterns
Annotation of Contours
And remember there are great discounts if you order AutoCAD with your KeyHOLE, and the support is included.
