【Resources】GDCad-Viki** version – software for drawing single-line diagrams of industrial pipelines (a classic choice, truly useful)

Thread Content

GDCad is a very useful software for drawing pipeline single-line diagrams; it can be used right after extraction. Download address: http://d.namipan.com/d/GDCad-Vik...1f1662313283a522300. Instructions for use: Drawing settings – Coordinate and initial elevation settings. 1.1 When the program opens a new drawing, an initial setup dialog box will appear automatically. In this dialog box, in addition to the program’s copyright notice, there are three parameters to be set: the two angles between the X and Y axes and the horizontal rightward vector line, as well as the elevation of the starting point of the initial pipe segment (initial elevation). Generally speaking: 1.2 The angles between the two coordinate axes and the horizontal line can use the program’s default settings, which are both 30°. 1.3 The initial elevation is determined based on the specific conditions of the pipes that are to be drawn. The default value of the program is 0. This initial elevation value will serve as the basis for the program to automatically calculate elevation values during subsequent pipe drawing. 2 Auxiliary Lines 2.1 Auxiliary lines refer to the direction auxiliary lines and length auxiliary lines that assist in displaying the direction and length of a pipe segment when the user draws it. 2.2 Direction guide line: The program automatically determines a direction guide line for the pipe segment drawn by the user, based on the axis orientation set in the initial dialog box and the position of the user’s cursor. This rubber band wire will determine the direction of the drawn pipe segment. 2.3 Length guide line: A rubber band-like line drawn by the program based on the position of the current user cursor and the starting point. This rubber band line will determine the length of the drawn pipe segment (pixel length). 3 Setting of image size 3.1 On the task bar at the top of the program’s interface, click the corresponding page setup button; this will bring up the page setup dialog box. Select an option and confirm it. 3.2 This program currently supports A3 and A4 paper sizes. 3.3 When the sheet settings are changed, the drawing frames in the sheet will be automatically adjusted accordingly. 3.4 Before printing the drawings, please check whether the printer’s drawing settings match the size of the paper format. 3.5 Adjusting the image size is merely to accommodate the size of the pipeline diagrams; whether using A3 or A4 paper, the paper orientation in the printer settings should be set to landscape when printing the drawings. 3.6 When printing various reports, regardless of the image size setting at the time, the paper size in the printer settings should be set to A4 in portrait orientation. 4 Setting of graphic line width 4.1 On the task bar at the top of the program’s interface, click the corresponding button for setting the line width; this will bring up a dialog box for setting the line width. In this dialog box, it is possible to set the graphic line width for main pipes, branch pipes, fittings, valves, and other objects separately. Once the settings are made, simply click OK. 4.2 If the line style of the objects being drawn is also to be specified, its line width should be set to 1; otherwise, the setting for the line style will be ineffective. 5 Setting of graphic line styles 5.1 In the task bar at the top of the program’s interface, click the corresponding button for setting the line style, and a dialog box for setting line styles will appear. In this dialog box, it is possible to select the line style to be used for drawing main pipes and branch pipes. 5.2 First, select the object types on the left side of the dialog box (multiple selections are allowed). 5.3 Then, on the right side of the dialog box, select the line style. 5.4 Final confirmation is required. 5.5 In the current version, the line style settings are only valid for pipeline objects (main pipes and branch pipes). 6 Setting of Graphic Colors 6.1 In the task bar at the top of the program’s interface, click the corresponding color setting button to bring up the color setting dialog box. In this dialog box, it is possible to set the drawing colors for all graphic objects. 7 Settings for the text (numbers) indicating pipes 7.1 The text used to indicate a pipe is primarily meant to show the length of that pipe, with the unit being millimeters (mm); this value may differ from the pixel length in the graphic. The program automatically calculates the pipe length based on this text (length value). If the indication consists of other text (other than half-width numerical values), or if no indication is given or it is blank, then the length of that pipe segment will not be calculated (or it will be 0). 7.2 In graphic drawing, after the user selects the start and end points of a pipeline (a forward-plying pipeline) on the diagram, the program will display the attribute table for the drawn object. By editing the input fields for the text items that can be modified in this attribute table and confirming the changes, the entry of the labeling text for that pipeline can be completed. 7.3 Once a pipe has been completed, if its text label needs to be modified, one can first click the attribute modification button in the task bar. The program will then automatically activate the snapping function, allowing the user to select the pipe segment that needs to be modified. After selection, the attribute table for that pipe segment will appear, and the remaining operations are the same as before. 8 Setting of the size for pipe fittings (elbows, tees, valves, etc.) 8.1 On the task bar at the top of the program interface, select the corresponding button for tees or elbows; this will bring up the setup dialog box for tees, elbows, and valves. By adjusting the drawing parameters for these elements, it is possible to change the size of such objects in the diagram. 8.2 Since this setting will be effective for all such objects, it should be applied before the first such object is drawn. 9 Settings for capture methods 9.1 On the task bar at the top of the program’s interface, select the corresponding capture setting to bring up the capture settings dialog box. 9.2 Capture is an automatic search function provided by programs to ensure that, when creating graphics, the starting point of a new object is connected to the ending point of the object it is connected to; or, during editing, to show which graphic objects the current cursor position applies to. The program uses different capture flags to display various capture modes. 9.3 There are three ways to capture targets: endpoints (marked with squares), midpoints (marked with triangles), and the nearest point (marked with crosshairs). 9.4 The setting of the capture method can be done at any stage of graph creation, and any combination of the three methods can be used (depending on the requirements at the time of graph creation). 9.5 In addition to these three capture methods, the program also provides a solder joint capture filtering function, which allows for the capture of only solder joints. Once this function is selected, the program enters automatic capture mode, during which only solder joints are captured, while all other objects are ignored. 9.6 During the drawing process, the program automatically activates (or deactivates) the capture function based on the user’s current drawing needs. The user should use the displayed capture indicators to determine the points that will be connected, and can also change the capture mode according to their own preferences. 9.7 The capture distance refers to the distance from the current cursor at which the program performs capture, that is, the effective radius of capture (in pixels). 9.8 Marker size refers to the size of the displayed capture marker (in pixels). 9.9
