Detailed explanation of the layout function in CAD software for beginners to CAD drawing

Thread Content

Many CAD drawing beginners will not be able to make good use of these functions if they do not have a thorough understanding of the functions in the CAD software when using Haochen CAD software to draw drawings. Next, let’s introduce the CAD layout function in detail to beginners of CAD drawing! Step 1 of using the CAD layout function: First use the Haochen CAD software to open the drawing, then double-click within the viewport range or use MS commands to enter the model space from the drawing space (please pay attention to the operation method), use zoom and pan and other methods to make the part you need to print appear within the drawing frame (usually we have to consider the final drawing ratio when drawing, so as to reasonably set the size of the text or equipment blocks in the drawing, otherwise the printed text may be too large or too small in the end) Operation step 2 of using the CAD layout function: Double-click outside the viewport range or use the PS command to return from model space to paper space (you can also click the model/drawing cut button on the bottom status bar). Select the viewport first. If you cannot select it directly, use frame selection (frame from left to right) as shown in the figure below. If the viewport coincides with the inner frame line of the frame, the frame line may be selected. If only the viewport is selected, the property box will be as shown in the figure below. If the viewport and other objects are selected, please select "Viewport" in the drop-down box at the top of the property box to display the viewport properties. At this time we can view and modify the characteristics of the viewport, which is mainly used to set the proportion of the drawing. The proportion of the viewport can also be modified in the viewport toolbar after selecting the viewport. As shown below: Step 3 of using the CAD layout function: There are two places we need to care about in the properties of the viewport, one is "Display Lock" and the other is "Custom Scale". “"Display Lock" is used to lock the viewport with the final proportions set, so that the viewport will not be adjusted repeatedly due to misoperation. How to know the custom scale? Usually different industries and different majors have some specifications. For example, architectural drawings are usually at a 1:100 scale, and community water supply and drainage will use a 1:200 scale. In short, a 1:1 drawn graph can be placed exactly on the drawing after being scaled to a certain ratio. Above, the proportion should be determined before drawing. Therefore, after setting the viewport and selecting a fixed proportion, enter the viewport and translate the graphics to the appropriate position. If necessary, you need to drag the grip points (corner points) of the viewport to change the size of the viewport. The proportion conversion method will not be introduced in detail here. If the drawing ratio is determined when drawing, the text height and the ratio of the equipment blocks need to be adjusted appropriately when drawing. For example, the drawing ratio is 1:100, and the text height required for printing drawings is 3mm. If drawing is based on 1:1, the text height should be set to 300, and the block size should also be set according to the requirements when inserting. Nowadays, Haochen CAD software has many professional software, such as Haochen Architectural Software and Haochen Mechanical Software. You can set the drawing ratio when drawing, and the software will automatically adjust the text height and block insertion ratio. The use of layout function is one of the very important steps in the process of using Haochen CAD software for CAD printing, so all beginners of CAD drawing are learning * In the process, you must understand the use of the CAD layout function!
