![]() The image will currently only be shifted and or scaled. Image Transform: This option moves a given Image in a backcloth by clicking on two locations within the image, and then providing new coordinates for the identified points.Report: Generates a text report on the values and errors within a given Transformation.Reverse: Applies the inverse of a selected Transformation, effectively undoing it.Apply: If a coordinate transformation has been created and saved within the project, this option allows a selected transformation to be applied to the current CAD database.However any objects on layers that are turned off will NOT be moved (Replaced in 4.30). Offset: Allows a fixed delta Easting and Northing to be applied to the entire CAD database.So essentially this tool shades two possible situations. Once the parameters have been accepted, the plot will be generated. If this is left at zero, and an eye ht offset applied to the Origin, then the analysis is "What can be seen from the origin" If however an offset is applied to this value and the origin left at 0, then its a "Where can the origin ground level be seen from" Height Offset: This is the height appended to the last position on the section.To make the process render "What can be seen from here", add onto this value a suitable eye height and leave the Height Offset at 0. Origin Level: This is the ground level the sections emanated from.The Visibility Parameters dialog then has two variables: Pick the one which relates to the visibility zone to be calculated. Having selected this option you are presented with a list of radial section databases. Ideally for this tool to work and plot a dense pattern the radial sections should be taken at least 1deg apart. Visibility Analysis: This is a quick tool to shades zones of visibility using radial sections to calculate what is and what is not visible.Boreholes Chart: Click here for more info.Transformation Values: This option allows you to select one or two points and then enter what the co-ordinates of the first point should be.Transform Coordinates: This option allows you to use 2pt or 2D transformations depending on how many points are being used.Grid Commit: Generates a user-definable grid inside a selected area or viewport. ![]()
