When picking points during these steps, use simple snaps ( End, Near, Point, Midpoint, Center, Intersection, and Quadrant) for greater precision.
Mesh vertices do not have to be turned on when using the Vertex snap. Use the CullControlPolygon to disable snapping to vertices on the back side of mesh objects. The Tan object snap is not effective for the first point for a command. Ellipses have quadrant points at the ends of the ellipse axes if the ellipse is oblique in addition to those at the construction plane extremes. The quadrant points of circles and arcs are at the extremes in each construction plane axis direction. Snap to the point on a curve that is at the maximum x or y point relative to the current construction plane. Snap to a point object, extrusion point, control point, edit point, block, and text insertion points.Īlso snaps to centers and corners of rectangular lights and block insertion points even if control points are not displayed. To snap to mesh wires, the SnapToMeshes command has to be enabled. Widgets alignment ¶ By default, the widgets are centered horizontally ( widgetalignmentALIGNCENTER ). The less trivial ones are explained here. It offers many parameters to let you adapt the behavior and the visual aspects of the menu. The Perpendicular object snap is not effective for the first point of a command. The pygamemenu.Menu is the base class to draw the graphical items on the screen. Snap perpendicular to a curve, mesh wire, or surface edge. 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. Multiple persistent object snaps can be set in the Osnap control.Īll object snaps behave similarly, but snap to different parts of existing geometry.įor example, the End object snap finds the endpoint of a curve. 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. The menu versions turn the object snaps on for one pick only.įor persistent object snaps, use the Osnap control.
