As for the cut angle processing of steel construction materials, as shown in Figure 7, it is a conventional cut angle setting interface for steel construction materials. It mainly uses the side length ratios of different cut angles to build the factory in advance. The required cut-off angle size list 71 is for the user to input the starting position value of the cut-off angle and the required cut-off angle size code in the programming page 72 to complete the preparation of the cut-off angle processing program. However, for this kind of cut-off angle size created by the aspect ratio, the required cut-off angle size list 71 must be created in the setting first, which is quite troublesome and time-consuming, and the angle setting of the cut-off angle is limited to 45 degrees or less. , It cannot be displayed if it exceeds.

As shown in Figure 8, another conventional cut-off angle setting interface for steel construction materials. This cut-off angle setting interface uses the method of marking the coordinate position to first build the required cut-off angle coordinate point list. 81, and it is also available for the user to input the starting position value of the cut-off angle and the required cut-off coordinate point code in a programming page 82 to complete the preparation of the cut-off processing program. and This way of marking the position of the coordinate point has no angle limitation in setting, but the parameters required for the coordinate position are quite complicated in setting, so there is also the problem that the setting is too troublesome and time-consuming.

In addition, the above two conventional methods are used for the cut-off angle setting interface of steel construction materials. The relevant parameter input is only presented in text and numbers. In addition to the situations where input errors are prone to occur, the parts that have been written are more due to It is presented in words and numbers, which is not easy to understand at a glance, so it is difficult to review the correctness of the programming, and it is extremely inconvenient to use.

In view of this, how to solve the above-mentioned problems is the primary problem to be solved by the present invention.

Preferably, the workpiece preview area simultaneously displays orthographic vector views of three different faces of the steel structure to be processed. And further, after selecting one of the orthographic vector views in the workpiece preview area, then selecting one of the truncated angle position graphics, and inputting the longitudinal and transverse length dimensions of the desired truncated angle, and then performing vector calculations The corresponding truncated area mark can be displayed on the selected orthographic projection vector view.
