Snap Mode Toolbox
The tools in the Snap Mode toolbox are used to set different snapping modes.
All tools in a toolbox are not always visible by default. To see all tools, right-click in the toolbox and select Show All from the menu.
With Snap Lock on, each snap mode setting has an effect on tentative snap points. When you enter a tentative point on or near an element, the following occurs:
|Snap Mode (or override):||Tentative point snaps to:|
The nearest of the Element keypoints on the element. This is the most generally useful of the snap modes.
Intersection of two elements. (Two tentative points are required, although more can be used.) The first tentative point snaps to one element, and that element is highlighted. The second tentative point snaps to another element, and the two segments used to find the intersection of the two elements are displayed in dashed lines. (If the two elements do not actually intersect, but projections of the elements would intersect, the segments include projections of the elements to the intersection.) You can continue snapping until the desired intersection is found; the last two tentative points define where the intersection snap lies.
An existing element — the edge of the element being placed is constrained to be tangent to an existing element. The tentative point dynamically slides along the element to maintain the tangency as you move the pointer to finish placing the element.
An existing element — the line you are placing is constrained to be perpendicular to the element — the tentative point slides dynamically along the element in order to maintain the perpendicularity as you move the pointer to finish placing the element.
Multi-snap mode 1 by default is Intersection, Keypoint, Nearest.
