The fourth part; Training content

1. How to draw curves with functions in cad? First, compile the data table according to the function in EXCEL, then copy the generated data, and paste the generated data with PLINE command in CAD. Second, when drawing, it is best to put different kinds of graphics and lines on different layers, especially large ones. In this way, when modifying, you can turn off the layers that don't need to be modified, leaving only the layers that need to be modified, which is much simpler. So I think it's good to build more similar floors, otherwise a mistake in one place will be big, especially complicated. Third, the operation of creating graphics 1 and dynamic graphics blocks ◇ Selecting the visibility of multiple graphics defines multiple appearance shapes that can contain special symbols. After insertion, the user can choose which appearance shape to use. For example, a block can contain multiple faucet views, multiple installation dimensions, or multiple valve symbols. When inserting a dynamic block with multiple different insertion points, you can traverse the insertion points of the block to find a more suitable insertion point. This can eliminate the need for the user to move the block after inserting it. ◇◇◇◇◇◇◇◇◇◇◇◇◇◇◇◇◇◇◇◇◇◇◇◇◇◇◇◇◇967 Editing block geometry Specifying grips in a dynamic block enables users to move, scale, stretch, rotate and flip some geometry in the block. Editing blocks can force you to specify between the maximum and minimum values, or directly select values from a fixed list of defined attributes. If there is a screw block, it can be stretched between 1 and 4 drawing units. When the screw is stretched, the length increases in increments of 0.5 units, and the thread will automatically increase or decrease during the stretching process. Another example is a numbered block with a circle, text and a leader. The user can rotate the leader around the circle, while the text and the circle remain in the original state. The third example is a door. Users can stretch the width of the door and flip the direction of the door axis. 2, data input and object selection ◇ View and input data near the focus of the line of sight. Users can dynamically view dimension values, such as length and angle, when creating and editing geometry, and switch between these values by using the TAB key. Users can use the newly set switching function in the status bar to enable the dynamic input function. A new label has been added to the sketch setting dialog box, which provides style, visibility and appearance for setting dynamic input function. ◇ Zooming and Translation For example, if the range is zoomed and the smooth conversion is started, the user can see that the graph dynamically changes from the partial view to the whole graph. Smooth view conversion helps users maintain visual orientation in graphics. Further improvement, the whole zooming and panning process can be treated as a single operation by setting. This setting is set in the User System Settings tab of the Options dialog box. It only takes one step to return to the previous view, which really saves time and effort. ◇ Selecting an object When the user's cursor scrolls over the object, the object will be highlighted, so that the user can see which one is selected, and a flipper will appear to flip the highlighted object. Another advantage of this is that you can judge whether a group of graphics is a single object (such as a polyline) or a single object (such as a line segment) without selecting an object. When multiple objects are selected, the translucent selection window can clearly see the object selection area.

Users can modify the object selection behavior by using the new controls provided in the Selection tab of the Options dialog box.

The fifth part; Training results

When I finished this training report, I carefully checked the part drawings I had drawn before, revised some shortcomings in detail, and then saved them on my mobile USB flash drive for printing tomorrow. This CAD training has benefited me a lot, not only consolidating the knowledge in the previous books, but also improving my own operation in CAD and deepening my hands-on ability in the process of drawing. At the same time, I also improved my understanding of CAD. The smooth completion of the big homework also thanks to Ouyang's guidance and correction. I'm grateful for that. At the same time, I also realized that as a civil engineer, it is not enough to just design a mold drawing. More importantly, I know how to use and control them, so that they can better serve the society and people.

The sixth part; Training experience:

In this week's training, we mainly practiced plane graphics and part drawings, and part drawings mainly practiced shafts, brackets and boxes. Plane graphics mainly let us review the basic instructions we have learned in class, while drawing part drawings is to improve our engineering practice ability and drawing recognition ability. Up to now, we have learned both manual drawing and mechanical CAD drawing. As we know, compared with CAD drawing, manual drawing is more particular, the lines are difficult to be unified, and the workload is heavy. Special tools, such as T-square and curve board, are needed to complete a complex drawing. And CAD drawing has the advantages of convenient operation, small workload, uniform lines and good visual effect. At the same time, we also know that drawing a CAD drawing needs the basis of manual drawing, and it is difficult to draw a qualified CAD drawing without the basis of manual drawing. Therefore, CAD training is not only a test of our CAD courses, but also an effective review of manual drawing.
