What do CAD xrefers do and how do I use them?

Generally in the building, different majors are drawn in different drawings, but some majors will use the drawings of other specialties, so they use external references, for example, if you do HVAC, the specific position of the pipeline needs to be used as a reference, and the external reference can be easily dismantled and loaded, which is convenient for the management of drawings and drawings. This major is placed in one folder, and other majors are placed in the corresponding folder, and if necessary, use the reference. For example, HVAC equipment, water pipes, and air ducts can be done in different diagrams, and water pipes and air ducts will refer to the equipment diagrams.

Xrefs are a useful thing. As the name suggests, it is a reference taken from the outside. Reference, that's a thing that can only be seen.

The most direct understanding is that you are designing a thing, but you have to open another diagram to see some data in it, and so on, always in exchange, how inconvenient, so CAD will help you introduce the concept of reference, you can directly refer to the diagram you always see, is it much more convenient.

The diagram that comes in cannot be modified, how good it is, and I am not afraid of being misoperated.

<>2. The "XRef" panel will pop up, as shown in the figure, we click the "Attach" button in the upper left corner, pop up the menu, and select "Attach DWG" (according to the graphic format you refer to, you can choose your own, and the DWG is to refer to the drawing on someone else's CAD drawing).

3. Then, we select the drawing we want to refer to, and after selecting it, click "Open".

(conducive to the automatic connection of drawings in the future), click "OK", and the xref is set.

The CAD drawing opening prompt does not have an external reference, which is caused by a setting error, and the solution is as follows:

2. The "XRef" panel appears, as shown in the figure, click the "Attach" button in the upper left corner, if you want to refer to **, click "Attach**", if it is other CAD drawings, then click "Attach DWG". Let's take other drawings as examples.

3. Click to attach the dwg, the "Select Reference File" option box appears, we select the drawing that needs to be referenced, and click "Open".

4. The "XRef" panel appears, as shown in the figure, it is best to select "Relative Path" in the path type, so that the reference base map can be automatically identified. Click OK and the xref is ready.

Summary. The method and detailed operation steps are as follows:

1. The first step is to open the CAD software, and then click the "Insert" - XRef option in turn to go to the steps below.

2. The second step, after completing the above steps, click the "Attach" option in the upper left corner, if you want to refer to **, click "Attach Image", if it is another CAD drawing, then click the "Attach DWF" option, take other drawings as an example, go to the steps below.

4. Fourth, after completing the above steps, select the "Relative Path" option in the "Path Type" option, and click the "OK" button. In this way, the problem is solved.

How CAD embeds inserted XRefs into CAD.

The method and detailed operation steps are as follows:

1. The first step is to open the CAD software, and then click the "Insert" - XRef option in turn to go to the steps below.

2. The second step, after completing the above steps, click the "Attach" option in the upper left corner, if you want to refer to **, click "Attach Image", if it is another CAD drawing, then click the "Attach DWF" option, take other drawings as an example, go to the steps below.

4. Fourth, after completing the above steps, select the "Relative Path" option in the "Path Type" option, and click the "OK" button. In this way, the problem is solved.

The display is incomplete because the drawings are not in the same folder, and they need to be placed in the same folder, and the specific steps for CAD to load XRef drawings are as follows:

The materials that need to be prepared are: computer, Tianzheng 2008.

Take win7 system and Tianzheng 2008 version of wax oak as an example:

1. First open Tianzheng 2008 and click to open the "XRef" in the insert.

2. Then click the first icon in the upper left corner of the pop-up window, and select to open the XRef sheet you want to load.

3. Then click on the pop-up window to select "Attachment Type".

4. Then click to open the option below the Road King type and select "Relative Path".

The correct steps for CAD to add xrefs to a drawing are as follows:

Tools Raw materials: Lenovo YangtianM4000E-06, Windows10,.

1. In the CAD menu bar, open the "Insert" drop-down menu.

2. In the insert menu, select the "External Reference" function.

3. On the XRef interface, click the "Attach DWG" icon.

4. Select "Attachment Type" in the reference type column, and click OK to join the drawing.

Advantages of CAD software:

1. Precision and accuracy: CAD software allows the use of precise mathematical and geometric algorithms to create and design. Compared to traditional hand-drawn designs, CAD is able to provide greater precision and accuracy, reducing errors and measurement biases.

2. Visualization and real-time preview: CAD allows designer Bi Min to visualize the design graphically. Designs can be previewed on-screen in real-time, enabling designers to quickly evaluate and modify designs for better results.

3. Convenient modification and: CAD software provides convenient modification and function. Handwritten sticker elements can be easily moved, copied, rotated, and scaled, making design changes and modifications faster and more flexible.

4. Rapid design iteration: CAD makes design iteration more efficient. Tongzhou Yu CAD software, designers can quickly try different design schemes, and estimate the effect. This speeds up the design process and shortens the development cycle.

The differences are: different dependencies, different updates, and different insertions.

First, the subordination is different.

1. Blocks: Blocks are saved inside the drawing.

2. Xrefs: Xrefs are independent external drawings that are referenced.

Second, the update is different.

1. Tile: Once the user inserts a tile, the tile will not be updated with the change of the original drawing.

2. XRer: Once the user inserts XRer, the XRaffer will be updated as the external drawing changes.

3. Insertion is different.

1. Block: When inserting a block, you can browse other drawings, but all the data of the inserted drawing will be read and saved to the current drawing.

Very easy to deal with, the steps are as follows: select the block, blow it up, and then blow up the block, if this block contains two layers (layer 1 and layer 2), we change it to another reserved layer, modify it (such as layer 3), so that we can clear it with the pu command, but the important point is that layer 0 and the currently selected layer cannot be cleared. The "defpoints layer" is an invisible layer and is not visible when you print it.
