Entity snaps enable you to quickly select exact geometric points on existing entities without having to know the exact coordinates of those points. With entity snaps, you can select the end point of a line or arc, the center point of a circle, the intersection of any two entities, or any other geometrically significant position. You can also use entity snaps to draw entities that are tangent or perpendicular to an existing entity.
You can use entity snaps any time the program prompts you to specify a pointfor example, if you are drawing a line or other entity. You can work with entity snaps in one of two ways
When using entity snaps, the program recognizes only visible entities or visible portions of entities. You cannot snap to entities on layers that have been turned off or to the blank portions of dashed lines.
When you specify one or more entity snaps, an entity snap target box is added to the crosshairs. In addition, an icon appears adjacent to the crosshair indicating the active entity snap. When you select an entity, the program snaps to the snap point closest to the center of the target box.
TIP If you type the name of the entity snap, you need to type only the first three letters.
One difference between IntelliCAD® and AutoCAD is that with IntelliCAD, you can type the entity snaps directly, instead of having to precede it with the osnap command. For example, to turn on center snap, you type center instead of osnap center. IntelliCAD uses all the same snap settings as AutoCAD, plus one more: a planview intersection snap. The planviewint command snaps to the point where entities would intersect if they were at the current elevation.
