Haochen CAD multi-line segmentation technique

In our process of drawing with CAD software, pruning is a very common command, which is generally used to trim off the extra parts at the intersection of primitives. So, how can we efficiently trim the primitives? Here? Let's take a look at the use of the trim command (using the software for Haochen CAD2012, you can log in to Haochen CAD official website to download: http://www.gstarcad.com/cad_7_74.html).

1. Intersection primitive trimming

For two or more intersecting primitives, we generally select one of the primitives as the trimming reference line, and the other primitive is trimmed according to the reference line ( As shown in Figure 1), this method is more commonly used in early CAD drawing, but because it always requires a single choice of trimming reference, it can not meet the needs of customers for fast drawing.

2, Quickly trim the primitives at the intersection

The principle is similar to the method described above, but the difference is that you do not need to choose this method. Referring to the primitive, as long as the object to be trimmed is selected by the <quo;tr” command, the primitive will trim off the extra primitive with reference to the intersection point (see Figure 2).

3, enhanced cut

In the Haochen CAD extension tool, there is an enhanced cut function. It can be based on the existing objects in the graph, such as polylines, lines, circles, arcs, etc., select the side of the primitive boundary that needs to be trimmed, and you can quickly trim the object (Figure 3).

In short, Haochen CAD's trimming function is increasingly diversified, and the operation is very simple. You can trim multiple elements at once, so you may wish to try it yourself.
