Regarding the CAD layout, I would like to ask what is the function of the layout in CAD?

Question: How can I synchronize the layout of drawing or modifying in model space?

Method:1In layout, also known as paper space, create a viewport with the Viewport command.

2.Double-click the left mouse button in the viewport to activate the layout, where you can see the model space, zoom in, zoom in, and modify it.

3.Set the ratio of paper space to model space, such as 1:100. Scale setting can no longer be done with the scale command, otherwise the scale will have to be set.

4.Modify the operation in the model space, and the paper space is changed synchronously; Double-click the left mouse button in the paper space viewport to enter the model space, and you can also modify the operation, and the model space will also change.

5.Double-click the left mouse button in the paper space viewport to enter model space, and double-click the left mouse button outside the viewport to enter paper space.

6.Operations performed in paper space are not visible in model space.

You should use the layering function of CAD, draw different categories in different layers, this will be very convenient, if the painting is done but not layered, you can use the Yanxiu toolbox to layer, it is also very fast.

If you feel that there are too many things in the model space and you can't see clearly, then freeze the layer where some unwanted things are located.

After the inside of the model was changed, the layout was also changed.

Isn't there a back button?

Viewport objects can be created and placed in a layout, and title blocks or other geometry can be added. You can create multiple layouts in a drawing to display different views, and each layout can contain different plot scales and paper sizes. The layout displays the exact same drawing as it is printed on the paper page.

2. Click on the layout at the bottom of the command bar (that is, the layout next to the model), and a blank file will be generated.

3. Next, enter the command: MV in the command bar, and then press the enter key, at this time, the crosshairs will change to a drag-and-drop shape.

4. Select a point arbitrarily, then drag and pull the mouse to form a layout box, release the right mouse button, and <>

5. Move the mouse to the box of the layout, and then double-click, the frame line becomes thicker, it means that the layout is done, and you can copy the diagram in the model.

For large maps that need to be processed with graphic segmentation, it is more convenient to work with them in the layout: (Take the route segmentation topographic map as an example) Step 1: Create a new layout.

Step 2: Page Setup.

Step 3: Add a frame.

Step 4: Create a new viewport: View --- viewport--- Create a new viewport (one viewport, two viewports--- Step 5: Drawing Model--- Find the shape you want to work on under the model.

Step 6: Rotate in CAD layout (an important step).

1. In the layout, after entering the viewport simulation space (that is, the graphic is activated, you can select elements in it): ucs enter;

z enter; 45 (required angle, e.g. 45) enter (you can also set a direction yourself, so that it is easier to grasp what kind of angle you want);

plan ；

Enter; Enter;

2. Use the mvsetup command to rotate the view

At the Command prompt, enter mvsetup;

Enter a (Align);

Enter r to rotate the view;

Select the viewport you want to rotate the view;

Specify the base point of rotation;

Specify the angle of rotation;

The entire view is rotated in the viewport, how CAD will enter the graphics in the layout 1.

Generally, UCS is used, which is more convenient, and each viewport is independent and does not affect each other. This saves you the trouble of turning around in the graph model and then laying it out!

Note: The rotation angle is based on the model space position.

Step 7: Handle the Graph Scale: View the Viewport Properties--- Process the plot scale in the custom scale (1:1000 graphics in the model is processed as 1:2000 graphs, custom as.

Note: After processing scale'Graphics cannot be scrolled with the mouse, and placement adjustments can only be adjusted with the command p.

Step 8: Viewport Clipping: Treat a rectangular viewport as a polygon viewport with viewport clipping.

The command is vpclip

The CAD viewport shortcut menu also has a shortcut key, which is a command to trim an existing viewport, that is, you can trim a normal rectangular viewport into a polygon viewport (a good command).

Partially hidden commands in CAD.

When there are too many CAD graphics in a picture, the machine reflects significantly slower. In particular, pasting and copying a large number of complex graphics is particularly slow.

This problem can be solved by the local hiding function of the CAD.

wipeout”。After input, you can delineate an area with multiple line segments, and the graphics in the area are hidden. After deleting the drawn multi-line segments, the hidden shape is displayed again. A very practical command. ;
