How to quickly bid the horizontal height in CAD?

You can first draw the elevation symbol with CAD, then use the shortcut key "att" to add the definition attribute, select "Verify" in the attribute flag, add the elevation value in the "Default Text", and then click in the "Insert Coordinates" to select the location of the elevation value on the elevation symbol. In the end, all the selections are made into blocks, and the next time you use them, you can directly insert the elevation symbol, and if you want to modify the elevation value, you can directly double-click the elevation value, and you can modify it.

Well, the eldest brother is already very detailed, give points

Click "Dimension" - "Linear" to mark the first dimension, and then press Enter to continue labeling.

1. First of all, click the toolbar on the left side of the open drawing file and select Symbol Dimension - Elevation Dimension.

2. Select the style of the elevation annotation in the pop-up elevation annotation, and set it to self-elevation.

3. Then set the location of first. Click Enter manually, and then click Enter 0 in the floor mark.

4. After the setting is completed, click the 0 position in the graph.

5. After setting 0, then click the right mouse button; Then click the elevation label in the menu bar again to enter the elevation dimension.

6. Finally, if you want to modify the elevation annotation that has been marked, you can directly double-click the left button to enter, and this is done.

You can't just find an average of all the levels, right? It is usually divided into blocks, but then there may be many points of elevation to be averaged together. You can program an autolisp program to solve it.

OpenCanvas is a drawing software, not an OC for computing

The construction plane is a specific plane in the CAD three-dimensional space, which is generally the XOY plane in the three-dimensional coordinate system. The construction plane is mainly used to place 2D objects and align 3D objects. Typically, the 2D objects you create are located on the construction plane, and the grid is displayed on the construction plane.

As shown in the figure below. If you do not specify the z-axis coordinates when entering the lead and go to the 3D drawing, or if you use the cursor to pick a point directly on the screen, the z-coordinate of the point will be consistent with the elevation of the construction plane.

By default, the construction plane is the XOY plane in the 3D coordinate system, that is, the elevation of the construction plane is 0. It is also possible to change the elevation of the construction plane, and you can draw directly on a plane parallel to the XOY plane.

The elevation refers to the default Z-coordinate demolition value in CAD, and the default elevation value is 0When you enter only the x,y value of a coordinate point in the command line, or use the cursor to pick up a point on the screen, CAD automatically specifies the z-coordinate value of the point as the current elevation value.

The command prompt for setting the elevation is as follows.

Command: elev

Specify the new default level <>:

Specify the new default thickness <>:

When the coordinate system changes, CAD automatically sets the elevation to zero and saves the elevation value in the system variable elevation, which can be directly modified to change the current elevation setting.

The elevations in the architectural drawings are very heavy and we can use CAD to annotate them. So do you know how to mark the elevation in CAD? The following is my method of how to mark the elevation in CAD, I hope to give you an answer.

The method of marking the elevation in CAD After the drawing of the basic drawing, we can mark the elevation of the drawing, and the elevation annotation should be drawn in the floor plan, adjust the drawing to a top-down plan, and select "Symbol Annotation - Elevation Annotation".

Figure 1 of the steps to annotate elevations in CADTo annotate the elevation, we need to label first, in the pop-up settings window, we check "Manual Entry", and then enter "%%" in the elevation bar above

Annotate elevation in CAD Step 2After entering "%%", we will move the mouse to the appropriate position of Hetan Noise, and the system will automatically appear in the prompt style, select the appropriate position to click the mouse to confirm the input.

Figure 3 of the steps to annotate elevations in CADAfter determining the elevation annotation, we will let the random annotation of other locations, check off the option of "manual entry", and the system will automatically annotate other locations according to .

Annotate elevation in CAD Step 4After the elevation annotation is completed in the appropriate position, we have completed the annotation of the basic drawing and elevation, and the elevation marked on the top-down floor plan will not be displayed in the elevation, so it should be annotated separately when drawing the elevation.

Annotate elevation in CAD step 5

The specific steps are as follows:

1. Open TENGEN drawing and CAD drawing, open the drawings that need to be marked to be marked, and TENGEN drawing has corresponding commands for elevation drawing, which is convenient for the formation of drawings.

2. Select the drawing command "Symbol Annotation - Elevation Annotation" in the left Tianzheng mapping toolbar, the system will pop up the corresponding setting window, and click OK after the setting is completed, you can enter the elevation drawing.

3. In the setting window of elevation annotation, select the style of elevation and other information, and the system will default to the elevation annotation based on the coordinate axis of the drawing.

Fourth, after determining the appropriate position, click the mouse to determine the position, pull the mouse up and down to determine the direction of the number of labeling, after the determination of the mouse click again to determine the direction of labeling.

5. After the direction and position of the elevation annotation are determined, start to set the length of the annotation, drag the mouse to adjust the length of the line, and click the mouse after completion, you can determine and output the group and elevation, and the determined elevation is marked as a green line.

Sixth, the use of CAD to draw the floor plan, so the elevation numbers basically need to be modified, first in the required position for annotation, after the completion of the annotation, press the space bar to exit the elevation annotation command.

7. When you start to modify the annotation data, you only need to double-click the annotation number to automatically enter the annotation modification command, and you can enter the relevant data information for modification.

8. If you need to enter the standard annotation of ", you need to double-click the elevation annotation graphic to enter the setting window of the annotation. In the "Floor Level" field, enter "%% and click OK when you're done."

9. After determining the modification of the elevation, it will automatically return to the drawing page, and you can see that the modified annotation display is not %%, but the standard annotation of ".

[Elevation] indicates the height of each part of the building, which is the vertical height of a certain part of the building relative to the datum (the zero point of the elevation), and is the basis for vertical positioning. The elevation is to mark the corresponding height of each part of the building, which is based on the elevation system of the Yellow Sea, Bohai and Zhuji, and also has the relative elevation of the building itself. Except for the building-related elevation, the others are generally only marked with size, and the standard of elevation is determined according to the thickness of the surface layer in the building floor practice.

The elevation is divided into absolute elevation and relative elevation according to the different datum selections.

Absolute elevation]: It is the elevation of the datum as the zero point stipulated by a country or region, and the average sea level of the Yellow Sea near Qingdao in summer is used as the zero point of the elevation in China; The calculated level is called the absolute level.

Relative elevation]: The starting point of the elevation is taken as the starting point of the elevation with the main ground height of the first floor of the building as zero, and the calculated elevation is called the relative elevation. Relative elevation is further divided into building elevation and structural elevation.

Building elevation: In the relative elevation, the elevation including the thickness of the decorative layer is called the building elevation, which is written on the decorative level of the component.

Structural elevation: In the relative elevation, the elevation excluding the thickness of the decorative layer is called the structural elevation, which is written at the bottom of the component and is the installation or construction height of the component. Structural elevation is divided into structural bottom elevation and structural top elevation.
