![]() ![]() For example, when using 30, you get snap points at 30%, 60% and 90%. If the percentage is less than 50, the curve is marked with multiple snap points. The curve is marked with temporary black points that are automatically snapped to. Snap to a curve a percentage from the end. Snap to and track over a surface until the command completes. To track over the whole polysurface, see the OnPolysrf object snap. The cursor changes shape to indicate that you cannot pick. Note: If you are tracking over a polysurface, the marker is restricted to the single selected face. This means how close you have to move the cursor to the point before the marker jumps to the point. You can set the Snap radius for object snaps. Only Cen, End, Int, Knot, Mid, Near, Perp, Point, Quad, Tan, and Vertex object snaps can persist. Use persistent objects snaps to maintain an object snap through choosing several points without having to reactivate the object snap. As the cursor passes over an object, the appropriate object snap displays. More than one object snap can be active at the same time. When activated, the end object snap constrains the marker to the endpoint of the curve closest the cursor. All object snaps behave similarly, but snap to different parts of existing geometry.įor example, the End object snap finds the endpoint of a curve. Multiple persistent object snaps can be set in the Osnap control. Object snaps can persist from pick to pick, or can be activated for one pick only. When an object snap is active, moving the cursor near a specified point on an object causes the marker to jump to that point. When Rhino asks you to choose a point, you can constrain the marker to specific parts of existing objects by turning on object snap modes. The object snaps constrain the marker to an exact location on an object such as the end of a line or the center of a circle. For persistent object snaps, use the Osnap control. ![]() Note: The menu versions turn the object snaps on for one pick only. ![]()
