The most common hole punching methods, techniques and precautions are summarized below. Except for Boolean operations, the rest are all performed in the editable polygon mode. All the punching holes here are round holes as an example, because the difficulty of round holes is relatively greater.

1. Boolean
The most common and easiest to think of is the non-duality operation to punch holes. To punch a hole at a specified position also needs to be combined with a snap alignment tool. There are two kinds of Boolean tools, one is ordinary Boolean and the other is super Boolean proboolean.
Comparing the difference between the two booleans, it is clear at a glance. Use Super Boolean!
2. Projection
Use the graphics merge in the compound object to project the shape that needs to be punched to the surface of the object, here I call it projection.
Select Shape Projection
Obviously, we see a projected circle on the box
and we can get a clean round hole.
Three, push and pull
The so-called push-pull method is just my personal habit of naming, that is, hold down the shift key and push the dough piece to the opposite side of the object to punch a hole. Sometimes you need to push it to the opposite side and then pull it back to complete the hole. Graphics are often directly connected to edges, which is not demonstrated here.
1. Push to the opposite side
2. Effect demonstration
4. The bridge tool can also open holes
After we have obtained the faces of the shape we want to punch on the two opposite faces of the object, we can directly use the bridge command to complete the punching, as follows: At this time, if the shape on the opposite face is also in the selected state, at this time
we Click the "Bridge" command directly, and you can open holes according to the shape, as follows:
This method is suitable for the situation where both surfaces have the same shape and the shape is selected, and it is different from the push-pull method mentioned in the third part above. Yes, the push-pull method only has graphics on one side, which can be selected according to the situation.
Five, point cutting angle
Select the point level in the polygon editor, and then select the command chamfer, and pay attention to setting the parameters. The higher the subdivision, the better the smoothness of the circle.
If you consider the tightness of the wiring, it is recommended to connect the four vertices and the center point before making the corner cut, as shown in the figure below:
We can compare the corner cut before the connection between the four vertices and the center point, and we will find that the corner cut here The subdivision is only 2, but the circle is already very smooth, so it is very rewarding for us to do more auxiliary work.
6. Graphite GeoPloy
Choose GeoPoly in the graphite tool to complete the round hole. We first construct a square on the surface where the hole needs to be punched. If it is not a square, the naturally punched hole will not be round. This can be done according to your own needs. The more subdivided grids, the better. sleek.
ctrl+backspace, remove the selected point, we can get a square surface, at this time we can use
Seven, cycle tool
In the graphite tool, find the loop (don’t look in the wrong place)
and click the drop-down arrow, a LoopTools will appear, and a Loop Tools setting box will pop up after clicking, and there is a circle at the bottom, click to make a The square becomes a circle.
If you want the circle to be smoother, you must subdivide the square into more points in advance. This is also the defect of this method of making round holes, it cannot adjust the subdivision smoothness.
