The measurement function is an essential feature in CAD drawing software, and calculating areas using CAD is a task that is carried out frequently. A common phrase you’ll hear is: \"Give me a CAD drawing; please measure the total area of this apartment layout, or calculate the area of the bathroom in this layout.\" Well, when it comes to measuring the area of bathrooms in an entire floor plan, we are touching on the topic we want to introduce to you today: how to quickly measure the area of specific parts in CAD drawings using CAD viewing software? For example: In this entire CAD drawing, we only want to quickly measure the area of the bathroom. How should we do that? Let’s take a look together! First, we open the CAD drawing of the bathroom whose area we need to measure, and locate the area that is to be measured, as shown in the figure below. Next, we need to activate the area measurement function to carry out the measurement. The location of this function in Haochen CAD ViewKing for computers is: Extended Tools → Measurement Functions → Area Measurement, as shown in the figure below. After activating the area measurement function, we select the various vertices of the area we want to measure on the drawing, thereby forming a closed shape, as shown in the figure below. Once the selection is complete, we press Enter, and the area of that region is displayed in the dialog box at the bottom of the interface, as shown in the figure below. The yellow dashed box represents the area we have selected for measurement. From the measurement results, it can be seen that the area of this region is 9620. If I were to say that the area of this bathroom is 9620 square meters, you surely haven’t seen such a large bathroom before, right? Even though it’s a villa, this bathroom shouldn’t be this big, right? Actually, what you said makes sense – 9620 m2 is definitely incorrect. So where lies the problem? Take a close look at the scale of 1:100 on the drawing; that’s where the problem lies. We forgot to perform the scale conversion. The default unit in the computer version of Haochen CAD is mm, so we need to convert it to meters. As a result, after applying the scale conversion, 96.2 m2 is the actual area of this bathroom. At this point, some friends might say that a 1:100 ratio is relatively easy to work with. But what if the ratio is something like 1:55 or 1:21 – irregular ratios – wouldn’t it be more complicated to deal with those? Actually, our desktop version has a function for setting the measurement scale, allowing us to set it directly there; this way, we don’t need to perform any further scale conversion on the measurement results. Location for setting the measurement scale: On the computer version, go to Advanced Tools → Measurement Settings. Here we adjust the measurement scale; since the original drawing uses a scale of 1:100, to ensure accurate measurements, we need to reverse this ratio by setting it to 100:1. After making the adjustment, click OK. Once the scale is set, we can proceed with the measurement, and the result will be the standard value we’re looking for, as shown in the figure below. It’s actually quite simple, but using the wrong method can make things rather complicated. That’s all for the tutorial on quickly measuring the area of a specific part in a CAD drawing using CAD viewing software~ Isn’t it very simple?
