1. Cycle selection
1. Alt+L (linear cycle)
The reason why I call it a linear loop is because it will loop through continuous lines, and it will keep looping as long as the lines are continuous.
Initially select 2 or more, and the function of initially selecting more than one is to indicate the direction of the recognition cycle for computer calculations.
If we only select one initial face, it will be cyclically selected in all directions that can be cycled. As shown below:
It features an upper loop that indicates direction.
2. Alt+R (circular cycle)
Like the linear loop above, we also need to specify the loop direction. If not specified, it will also loop in the direction of the continuous line.
But our instructions here are different from those above.
It is characterized by circular circulation in the vertical direction of the indicated direction. In general ALT+L is more powerful, because ALT+R doesn't work after specifying two directions! As shown in the picture below, there will be no response to alt+R, but there is no problem with alt+L.
3. The difference between alt+R and alt+L in online selection
We have an alias for alt+R online level selection, called parallel selector, as shown in the figure below:
This feature can just be used by us to select the two sides of the line to be connected, as shown in the figure below, after we select the line below, we can quickly select the line above that is parallel to the line through alt+R (it will not be Multi-choice):
while alt+L is the same as double-clicking a certain line when selecting an online level, we can select a continuous line connected end to end by double-clicking, or by selecting a small section of line and then alt+L :
4. Cooperate with the mouse cycle selection
Press and hold shift to move the mouse to select the object where it moves.
Click an object, hold down ctrl, and double-click the adjacent object to complete the circular selection.
Click an object, hold down ctrl, and double-click an interval of n objects, then there are n consecutive objects.
2. Interval selection
1. Choose one every other
For interval selection, we use the dot loop oppsite in the loop selection, here you can set the number of intervals, the default is 1, of course, we often use this is enough.
Initially select 2 faces, set the dot gap to 1, and the default value is enough.
2, choose two every other
As shown in the figure below, how to operate when selecting two and one apart?
The default value of dot gap cannot be 1 at this time, but should be set to 2 by default. Is it unexpected? ? ?
The initial selection is three faces
3, choose two every two
Set the dot gap to 3, the initial selection is 3,
4. Choose one every three
The initial selection is 4, and the dot gap is set to 3
5. Summary of surface interval selection
The number of your initial selection should be 1 greater than the number of the final selection. If your final selection number is greater than 1, and the interval number is also greater than 1, then the corresponding initial selection number and interval number should be increased by 1.
6. Line interval selection
The interval selection of a line is different from that of a surface. Click a line segment to start the interval selection. No matter how many intervals are in the middle, you only need to select a line segment as the start, as shown in the figure below: The article may be updated at any time, please indicate the original article when
