Blender 04 ring cutting and offset ring cutting tool full solution (edge loop principle + full resolution ring cutting and offset ring cutting tool)
1 Principle of loop edge transfer
1.1 Fundamentals
Prerequisite: When Blender Preferences→Input→Mouse→Simulate 3-button mouse is not turned on
① alt + left click on a side: the row/column of the side will be selected
② ctrl+alt + left click on a side: the side and the side will be selected Associated with it
(as shown in Figure 1)
1.2 Principle
Program principle :
For a quadrilateral, when a side of the quadrilateral is selected, there will be two adjacent sides, and the remaining side is the side opposite to the selected side. Thus, you can use this method to select a side to find its corresponding side-by-side;
choose a side to change to a, and there are three sides (bcd) connected to it...but two (bc) are in the same plane as a, thus d is the transfer direction.
Based on the above principles, the tool "circumcision" is obtained.
2 two chestnuts
Circumcision shortcut key: [ctrl+r]
2.1 eg1
(As shown in Figure 2): ① was originally cut out by connecting two points with shift+j, and ② can be quickly obtained by using the circumcision tool (ctrl+r).
2.2 eg2
I hope to get the effect (as shown in Figure 3) (when ctrl+alt+left click) merge the vertices to the point of the two circles
Result: (as shown in Figure 4)
3 circumcision tool
3.1 Basic operation of circumcision
Ring cutting shortcut key: [ctrl+r];
mouse wheel increases/decreases "cutting times";
after selecting "cutting times", the cutting is limited to a certain range of the object, to close the range (as shown in Figure 5) alt or c,
Get a cut that defies the range (as shown in Figure 6);
If you directly right-click to cancel the sliding, it is the original cutting.
PS: For the above sliding cutting, press the ctrl key for adsorption movement, and press the shift key for fine-tuning movement.
3.2 Ring and slide (bottom left toolbar)
Smoothness effect (as shown in Figure 7);
The coefficient controls the slip. If you want to defy the range, turn off the "clamp";
when performing ring cutting like (Figure 4), if one side is non-linear, it will be cut according to the effect of the two lines. If you want to follow one of the sides for circumcision, turn on " Uniform " and follow the other to start " flip ";
UV Editing: (turn on the upper left "UV Selection Synchronization") "Correct UV" → synchronous slip.
3.3 Offset ring trimming
Similar to chamfering , but when encountering a non-linear line, the effect of cutting is similar to ring cutting (as described in 3.2); the
special option "capping end point": it is if you select a part of the line segment! Chamfer (ctrl+b) ! A cap (as shown in Figure 8) will be generated when using the "Offset Ring Trimming", but by default there is no cap, if you want to use it, check the "Cap End".
