You can refer to the following steps to adjust from 1: 1 to 1:300. Although the values are different, the operation method is the same.

1. At first, we finished drawing the scale map, but at this time, the scale obtained by labeling is 1: 1, which does not meet the labeling requirements.

2. Click the label menu, and then select the label style from the menu. A label style manager will pop up, and you can choose to modify it in the style manager.

3. Select the main unit menu page in the Style Manager and adjust the measurement unit ratio from 1 to 300.

At this point, we are drawing a line with the unit of 100 on the map, and then marking it.

5. You will see 30,000 mark units. The following figure shows the effect of the tag.
