Mô tả: Autodesk Land Desktop and Civil Design Tutorial 1-85 Autodesk Land Desktop Tutorial Nha Trang 04-2008 Duy Cò Autodesk Land Desktop and Civil Design Tutorial 2-85 Welcome to the Autodesk Land Desktop tutorial. This tutorial has 20 lessons about projects, points, labels, surfaces, volumes, and alignments. You can work through these lessons sequentially, or you can do one lesson at a time. Every lesson, except for the first one, has a tutorial drawing and an accompanying dataset. Click ⇒ at the top of this tutorial window to move to the next task. Tips for Using this Tutorial You'll use the Land Desktop 2004 menu palette when working with all of these lessons. The quickest way to load the Land Desktop 2004 menu palette is to type MLD and press ENTER at the command line. -You can close the Project Workspace (dockable window on the left of the AutoCAD screen) because it is not used in the tutorial. -The tutorial window stays on top as you work with Autodesk Land Desktop. If you do not want the tutorial window to stay on top, select OptionsKeep Help on TopNot On Top. -Working through these lessons will result in alteration of the project files. Backup copies of these project files can be found in the c:\Program Files\Land Desktop 2004\Landtut folder. If this lesson has been previously run, copy these unaltered project files to the \Land Projects 2004 folder when starting a new tutorial session to ensure that the sequence outlined in each lesson can be followed properly. LESSON 1: Working with Projects One of the first requirements of working with Autodesk Land Desktop is that your drafting and designing environment (your drawing file) must be linked to a project. A project is simply a storage area for a drawing's associated data, which can include points, surfaces, alignments, pipes, parcels, and survey observations. Project data is not stored in the drawing, but in separate folders on your system. To work through this lesson follow these steps 1 - Start Autodesk Land Desktop if you have not already done so. 2 - On the Projects menu, click Menu Palettes to display the Menu Palette Manager dialog box. 3 - From the Menu list, select Land Desktop 2004, and then click Load. Working through these lessons will result in alteration of the project files. Backup copies of these project files can be found in the c:\Program Files\Land Desktop 2004\Landtut folder. If this lesson has been previously run, copy these unaltered project files to the \Land Projects 2004 folder when starting a new tutorial session to ensure that the sequence outlined in each lesson can be followed properly. Creating a New Drawing and Project Start a new drawing and create a new project to store associated data. 1 - On the File menu, click New to display the New Drawing: Project Based dialog box. 2 - Enter Lesson_1 for the Name. 3 - In the Project and Drawing Location section, verify that Project Path list displays \Land Projects 2004\, and then click Create Project to display the Project Details dialog box. 4 - In the Initial Settings for New Drawings section, from the Prototype list, select Default (Meters). 5 - In the Project Information section, enter Project_1 for the Name. 6 - Enter Project for Exploring Land Desktop Startup for the Description and Training for the Keywords. 7 - In the Drawing Path for this Project section, verify that Project "DWG" Folder is selected. 8 - Click OK to return to the New Drawing: Project Based dialog box. 9 - In the Select Drawing Template section, from the Template list, select aec_m.dwt. 10 - In the Project and Drawing Location section, verify that the Project Name list displays Project_1 and the Drawing Path list displays \Land Projects 2004\ Project_1\dwg\. 11 - Click OK to create the new drawing and project. Setting Up the Point Database Nha Trang 04-2008 Duy Cò Autodesk Land Desktop and Civil Design Tutorial 3-85 Specify the parameters for formatting the point database. 1 - As the Create Point Database dialog box is displayed, verify that the Point Description Field Size is 32 characters. There is an additional field in the point database for point names, which stores alphanumeric point numbers or unique point names that may be used interchangeably with point numbers in many point commands. The point number field for the point database is still the primary field by which points are sorted and grouped. 2 - Select the Use Point Names check box, and then verify that the Point Name Field Size is 16 characters. 3 - Click OK to continue. Setting Up the New Drawing Specify the parameters for the new drawing. 1 - As the Load Settings dialog box is displayed, verify that the Path is \Program Files\Land Desktop 2004\Data\Setup. 2 - In the Load a Drawing Setup Profile section, from the Profile Name list, select m500.set (Metric, 1:500), and then click View to display the View Drawing Setup Profile dialog box. The coordinate zone, text style, and drawing border listed need to be changed for this drawing, so in the following steps you will make the appropriate edits to the drawing setup. 3 - Click OK to return to the Load Settings dialog box, and then click Load to load the m500 setup profile. 4 - Click Next to display the Units dialog box and verify the units settings. 5 - Click Next to display the Scale dialog box and verify the scale settings. The horizontal drawing scale affects block insertion and the size of text that is automatically created. The vertical drawing scale controls only the default vertical exaggeration of profiles and cross sections created by Autodesk Civil Design. 6 - Click Next to display the Zone dialog box. 7 - From the Categories list, select UTM, NAD 83 Datum, and then from the Available Coordinate Systems list select UTM with NAD 83 Datum, Zone 11, Meter; Central Meridian 117d W. 8 - Click Next to display the Orientation dialog box and verify the orientation settings. 9 - Click Next to display the Text Style dialog box, from the Style Set Name list, select mleroy.stp, and then click Load to load the mleroy text style. 10 - From the Select Current Style list, select L100. 11 - Click Next to display the Border dialog box. 12 - In the Border Selection section, select Scaled Block, and then in the Custom Block section, click Browse to display the Select a Custom Block dialog box. 13 - From the list select pm_841x594.dwg, and then click Open to return to the Border dialog box. 14 - Click Next to display the Save Settings dialog box. If this is a drawing setup that you would like to use on a regular basis, enter a profile name and save the setup. 15 - Click Finish to complete the drawing setup process. 16 - As the Finish window is displayed, verify your final drawing settings, and then click OK. Your drawing is now set up with the correct parameters. Reviewing the Project Directory Structure Take a look at the project directory structure with Windows Explorer. 1 - Open Windows Explorer and navigate to the Land Projects folder. 2 - Expand the Land Projects 2004 folder to view the separate project folders. 3 - Expand the Project_1 folder to view the separate folders that store different types of project data. All point data is contained in the cogo folder, including Microsoftâ database (.mdb) files for point groups, description keys, and user-defined external data references. The dwg folder contains the drawing files associated with the project and the .dfm files (which are ASCII text files that contain default drawing settings). Nha Trang 04-2008 Duy Cò Autodesk Land Desktop and Civil Design Tutorial 4-85 The survey folder is where raw files downloaded from data collectors are stored, as well as field book, observation database, and traverse adjustment files. This folder is empty until you use Autodesk Survey to populate the folder with these files. Additional folders are automatically created when you use Autodesk Land Desktop to work with surfaces (dtm), alignments (align), parcels (lots), and volumes (er). Additional folders are automatically created when you use Autodesk Civil Design to work with pipes (pipewks), hydrology (hd), and sheet manager (cd). This concludes the project creation lesson. In the next lesson, you'll learn about changing the project settings. LESSON 2: Changing Project Settings Copy projects to use project data with other drawings. Change drawing settings to specify new annotation, object creation, and calculation defaults. To work through this lesson follow these steps 1 - Start Autodesk Land Desktop if you have not already done so. 2 - On the Projects menu, click Menu Palettes to display the Menu Palette Manager dialog box. 3 - From the Menu list, select Land Desktop 2004 and then click Load. The default location folder for project files is c:\Land Projects 2004. If you opted to install these files in another location instead, specify the appropriate project path. Working through these lessons will result in alteration of the project files. Backup copies of these project files can be found in the c:\Program Files\Land Desktop 2004\Landtut folder. If this lesson has been previously run, copy these unaltered project files to the \Land Projects 2004 folder when starting a new tutorial session to ensure that the sequence outlined in each lesson can be followed properly. Copying a Project and Re-associating the Current Drawing A portion of the Lesson-2 tutorial drawing must be worked on as a separate project. Since some of the important data is not stored in the drawing but is stored in the project files, a copy of the project is required. You can not copy an active, current project. To copy a project, start a new session of Autodesk Land Desktop and, before starting a named drawing or associating it with a project, open the Project Management dialog box and use the Copy option. 1 - From the Projects menu, click Project Manager to display the Project Management dialog box. 2 - In the Project section, from the Name list, select Tutorial1, and then click Copy to display the Copy dialog box. 3 - In the Copy Project To section, enter TutorialC for the Name. 4 - Enter Building site - Northwest corner for the Description, and then click OK. The copied project has the same directory structure as the original project, with the same files populating each folder. 5 - As an AutoCAD message dialog box is displayed, click Yes to change the project association and to return to the Project Management dialog box. 6 - Click Close to close the Project Management dialog box. Use the following steps to open the Lesson-2 tutorial drawing. 7 - On the File menu, click Open to display the Open Drawing: Project Based dialog box. 8 - From the Project Name list, select TutorialC, from the Select Project Drawing List, select Lesson-2.dwg, and then click OK. Changing Drawing Setup Parameters Change the horizontal drawing scale and see how text height is affected. At the current horizontal scale of 1:500, the 2MM text style is 1 drawing unit high. The plot scale for a 1:500 scale drawing is 2 with plotting units in millimeters. This results in 2MM text style being plotted with a 2 mm height. 1 - On the command line enter ST to display the Text Style dialog box. Nha Trang 04-2008 Duy Cò Autodesk Land Desktop and Civil Design Tutorial 5-85 2 - From the Style Name list, select 2MM, in the Font section, enter 1 for the Height, click Apply, and then click Close to continue.
