1. When you choose to modify the font height directly in the feature, you only modify the font height of the selected note; Unchecked items will not be modified. If you want to modify all labels in a drawing or an area, you can quickly select them and then modify them in the properties.

First, open the characteristics of CAD (Ctrl+ 1), or click the icon in the toolbar to realize it.

2. Select the note to be changed, and click to select a smaller number (for a larger number or a certain area, you can use multi-selection for quick selection). At this point, you can see that in the left feature, the height of the text below the text is displayed as 2500.

3. Change the text height directly to 1000 here, and you can see that the marked text directly becomes smaller. Fill in the text height according to the required height. This modification can only change the modified label. If you want subsequent labels to be marked according to a certain word height, please see the second method.

4. The second method is to modify the standard text height directly by modifying the annotation style. After modification, all the standards of this style are directly modified, and there is no need to select a label. Click Label → Label Style to enter the Label Style Manager.

5. In the Label Style Manager, select the label that needs to be modified, and then click Modify. If you don't know which label style to modify, you can click the style, and then click Properties. See others.

6. When modifying the annotation style. Click on the text below the text appearance to check the text height, which is 2500 before modification (the same as in the feature). Now change it to 1000. Then click OK-Close.

7. At this time, you will find that the marked text becomes smaller. After that, this label is based on the revised style standard. This method cannot be used to modify a standard whose features have been modified in the first step. Complete the renderings.
