![]() ![]() In this case we wish to Draw a grid and we will use DOTS. This will use the settings we chose and allow us to generate a Grid for the drawing. Now that the options are set as desired, we can run the GRID command under the Modelling menu. If you find you do need them then please refer to the on-line help for more details on the options. The rest of the dialog box can be ignored by most of our customers as the options are very specific to the type of work you are doing and most do not require the options. This allows you to control which survey point to reference the grid to. The example above shows it using a point of 0,0. If you Enable the Grid Registration then you can specify a base point that the grid will be forced to go through. Grid Registration when not enabled, will see the Grid start in the lower left corner and fit the grid in as best it can but the grid will not match and specific survey points. Turn the Auto off and specify the X and Y spacing manually. The program will give you an arbitrary spacing that will normally not be what you need. If Cell Size is set as Auto, then you do not know what the Grid spacing will be. This allows us to control the spacing between the grid lines and where the grid lines start so they can match your survey datum. The 2 important sections of this dialog for drawing a Grid are, Cell Size and Grid Registration. Under the Modelling menu ->Configuration Settings ->Grids. Lets look at the defaults available to control the Grid. Now we have a Surface ready to create a Grid. If you have Breaklines to extract then follow the same procedure as we did for points, using the same surface name. Simply pick on ok and then select all the points in your drawing. This will ask you for the surface name to use, and defaults to GROUND. To create a surface (I am going to show you a simple way that may not always be the correct way for your data), go to the Modelling menu ->Extract From Drawing ->Extract to Surface. Before we look at a few of these options we need to remind you that to use this Grid command you first need to create a surface using Modelling. The Modelling Grid command has Many options that can affect how the Grid appears on screen. That would be 20 feet in imperial jobs or 20 meters in metric jobs. How much space should there be between each grid line in both the vertical and horizontal direction? The example above used 20 in each direction. Grid drawn as lines crossing the entire Grid area (shown with labeling at axis ends only as described in"b"above) Is the Grid to be drawn as lines crossing the entire Grid area or by drawing short line segments forming small crosses at each intersection of the axis? Grid label at the end of each axis only (shown using small crosses as described in"c"below) Grid label at each Axis intersection (shown using small crosses as described in"c"below) You can use the 2 Pick buttons to allow you to visually pick or, with the use of object snaps, allow you to accurately pick the locations desired to control where the grid will be drawn on screen.ĭo you want to label the grid at every axis or just on the end of each axis line? You specify the lower left corner to start drawing the grid at and the top right corner to stop drawing the grid at. There are four sections to this dialog box: The following dialog comes up on screen for you to fill in as desired. The Mapping Grid command is found under the MicroSurvey pulldown menu ->Drawing Utilities. ![]() We can then add them to our Survey Database so they can be staked out in the field. ![]() If this command is used in conjunction with a Surface then we can Drape the points onto the Surface and have them take on the elevation of the surface at that point. If it was 3D then all of the new points have the same elevation. The new points will be copies of the original so if it was 2D then the others are 2D. This command allows you to start with a simple point and create a Grid of points by specifying the number of rows and columns along with the spacing for each. The Grid is not labeled and if you need to upload points to a collector to stake the Grid out in the field then you will need to add the dots to our Survey Database. The Grid is in full 3D and can be drawn as lines or dots. ![]() This is a powerful 3D command allowing you to draw a Grid over a job based upon a Surface. This command does not deal with elevations. You can label each Grid intersection or only the ends of each Grid line, your choice. The Grid can be drawn to look like little plus signs or full Grid lines across the entire job. If all you need to do is draw a grid on top of your drawing as a visual reference then this command will do just that for you. Posted by Jason Poitras on 14 July 2015 10:18 AM ![]()
